Account checks
An ACCOUNTCHECK request allows a card to be validated by checking the cardholder’s first line of address, the cardholder’s postcode and the security code, to ensure the details entered by the customer are valid. Click here to learn more about the checks performed.
Requirements
- Account checks are only available for certain acquiring banks. Before you begin, please contact our Support Team and ensure your acquiring bank supports this functionality.
- Account checks can only be performed for card-based payment methods.
Failure to submit these fields will result in a “60025” (Invalid request) error being returned in the response.
Update your payment form
You can update your payment form to instruct our JavaScript library to process an Account check prior to performing a standard transaction. This is done by specifying custom requestTypes, as shown in the example below:
<html>
<head>
</head>
<body>
<div id="st-notification-frame"></div>
<form id="st-form" action="https://www.example.com" method="POST">
<div id="st-card-number" class="st-card-number"></div>
<div id="st-expiration-date" class="st-expiration-date"></div>
<div id="st-security-code" class="st-security-code"></div>
<button type="submit" id="st-form__submit" class="st-form__submit">
Pay securely
</button>
</form>
<script src=<DOMAIN>/js/v2/st.js></script>
<script>
(function() {
var st = SecureTrading({
jwt: 'INSERT YOUR JWT HERE'
});
st.Components({"requestTypes":["ACCOUNTCHECK","THREEDQUERY","AUTH"]});
})();
</script>
</body>
</html>

Best practices
When receiving our response, your system will need to perform the following checks on the values returned (where applicable) to ensure the request was processed successfully.
Error code
The errorcode is a fundamentally important field as it displays the outcome of the submitted request. It is returned in every response from Trust Payments.
If the errorcode is “0”, this indicates the request was processed successfully.
It is imperative that you have a process in place to check the final status of the processed request, by looking at the values of the other fields returned.
If the errorcode is “30000”, this indicates a field error.
If you look at the errordata field returned, this typically contains the name of the field that was deemed invalid. You will need to retry the request, ensuring all required fields have been submitted, and that all submitted field values follow our specification.
If the errorcode is “70000”, this indicates a payment was declined by your bank.
We recommend that you show an error message to the customer and allow them to try a different method of payment.
If the errorcode is “60010”, “60034” or “99999”, there has been a problem processing the request and the final status is not known.
This can be due to a communication problem with a bank or third party. In such cases, we recommend informing the customer of the problem and to contact you to query the issue. You will need to contact our Support team, providing a copy of the entire request submitted and response returned, and we will contact the relevant parties to establish the status of the request. In the interest of security, ensure you omit or mask sensitive field values, such as card details.
If the errorcode is not listed above, please refer to our full list of errorcodes for assistance. If you need further help, please contact our Support team.
Settle status
It is important to check the value of the settlestatus when processing an AUTH or REFUND request, as this indicates if Settlement will be performed. Here are the basics:
If the settlestatus is “0”, “1” or “10”, you do not need to take any further actions.
The transaction is currently scheduled to settle.
If the settlestatus is “100”, the transaction has been settled.
You cannot perform any further updates to the transaction.
If the settlestatus is “2”, the transaction has been suspended.
Funds will not be settled without your intervention. Please refer to our settlement documentation for further information.
If the settlestatus is “3”, the transaction has been cancelled.
Funds will not be settled and you will need to investigate the problem and try again. In this scenario, it is useful to look at the accompanying errorcode as this will often inform you of the reason behind the transaction failing.
If you haven’t already, we recommend you read our settlement documentation for further detail on how settlement is performed.
Security response
If the AVS and Security Code Checks are performed as part of the request (as is the case for most AUTH and ACCOUNTCHECKs), you will need to check the three security response fields returned, which are defined as follows:
- securityresponseaddress – Does the first line of the billing address entered by the customer match that found on their bank account?
- securityresponsepostcode – Does the billing postcode entered by the customer match that found on their bank account?
- securityresponsesecuritycode – Does the security code entered by the customer match the value found on the back of their card?
If the value is “2”, the customer entered the correct details.
If all values are “2”, there is no reason here to prevent the transaction from settling.
If the value is “1”, the bank was unable to check the customer’s details.
This may be because the customer has a card issued by a foreign country, and your bank was therefore unable to check their address. You may need to consider suspending transactions that fall into this category to allow you to investigate before proceeding with the payment.
If the value is “0”, the customer’s details were not sent to the bank.
This is because the customer didn’t enter any of the details at all, or that these details were not submitted in your request. You may need to consider suspending transactions that fall into this category to allow you to investigate before proceeding with the payment.
If the value is “4”, the customer entered incorrect details.
By default, we will suspend transactions where the security code entered by the customer fails to match the value on their card. Depending on your preferences, you may also prefer to suspend transactions where the address details do not match (disabled by default).
You can request that Trust Payments automatically cancels transactions when the security response fields have a certain value. As mentioned above, we suspend all transactions where the security code entered by the customer fails to match the value on their card. You can specify the circumstances under which transactions are suspended to match your own preferences (you can even disable such checks entirely). This is achieved by modifying your Security Policy. To discuss changes to your account’s security policy, please contact our Support team.
Request type description
Each response will contain a requesttypedescription. The value of this field returned in the response should always match the value submitted in the request.
e.g. If you are sending an “AUTH” request, ensure the requesttypedescription returned is “AUTH”.
If you receive requesttypedescription with value “ERROR”, the request may not have been processed successfully and you will need to investigate.
Live status
Check the live status value returned is “0” while testing and “1” when processing live payments.
Amount & currency
When submitting an amount and currency, check that the same values are returned in the response.
Response site security
If you are processing transactions using our Payment Pages interface, and have configured URL notifications or redirects to be triggered upon transaction completion, you will need to re-calculate the site security hash using the fields returned and check it matches the corresponding hash returned from Trust Payments. This is to ensure the content returned hasn’t been modified by an unauthorised party. Click here to learn more.
Account checks (API)
If you are unsure, please contact our Support Team for assistance.
An ACCOUNTCHECK request allows a card to be validated by checking the cardholder’s first line of address, the cardholder’s postcode and the security code, to ensure the details entered by the customer are valid.
Process overview
-
- Merchant submits ACCOUNTCHECK request.
- Trust Payments validates the request and contacts the bank.
- The acquiring bank will contact the card issuer to perform AVS and security code checks.
- Trust Payments receives results of the request and passes this back to the merchant.
- Merchant receives and interprets this response.
The customer’s account is not debited when an ACCOUNTCHECK request is performed.
Requirements
-
-
- Account checks are only available for certain acquiring banks. Before you begin, please contact our Support Team and ensure your acquiring bank supports this functionality.
- Account checks can only be performed for card-based payment methods.
-
Failure to submit these fields will result in a “60025” errorcode being returned in the response.
ACCOUNTCHECK request
The fields required in an ACCOUNTCHECK request are the same as a standard AUTH request. The difference is that the baseamount can be “0”. You can also submit any field that you can submit in an AUTH request and these will be inherited by any subsequent child requests.
The following is an example of an ACCOUNTCHECK request:
#!/usr/bin/python import securetrading stconfig = securetrading.Config() stconfig.username = "[email protected]" stconfig.password = "Password1^" st = securetrading.Api(stconfig) accountcheck= { "currencyiso3a": "GBP", "requesttypedescriptions": ["ACCOUNTCHECK"], "sitereference": "test_site12345", "baseamount": "0", "orderreference": "My_Order_123", "accounttypedescription": "ECOM", "pan": "4111111111111111", "expirydate": "12/2020", "securitycode": "123", "billingpremise": "789", "billingpostcode": "TE45 6ST" } strequest = securetrading.Request() strequest.update(accountcheck) stresponse = st.process(strequest) #stresponse contains the transaction response

ACCOUNTCHECK response
The ACCOUNTCHECK response has the same structure as a standard AUTH response, except for the requesttypedescription value returned being “ACCOUNTCHECK”.
Inheritance
It is possible to take the value of the transactionreference field returned in the ACCOUNTCHECK response and submit this in the parenttransactionreference field of a new request, such as an AUTH. The new request will inherit billing and delivery details from the ACCOUNTCHECK (including the card details required for the payment), which means you are not required to submit this information again.

Transaction queries
If you are unsure, please contact our Support Team for assistance.
If you would like to retrieve information on requests and transactions you have previously submitted, you can submit a TRANSACTIONQUERY request.
Process overview
Your system will need to submit a TRANSACTIONQUERY request to Trust Payments. Trust Payments will then return a response containing the requested information, if a matching request has been found.
For example, you can request information on all transactions processed on your Site Reference between 6pm and 9pm, or find out whether or not a transaction has been settled.
Filters
The TRANSACTIONQUERY request consists primarily of filters. Think of filters as search criteria; the response returned will contain information meeting the specified filters.
For example, a filter with orderreference “100100” would return details of all matching requests with that reference (if any exist and have been processed on your site reference).
And specifying a starttimestamp and endtimestamp will return details of all requests processed on your account between the specified times.
Multiple records can be returned in a single response
We recommend being as specific as reasonably possible in your request, by submitting as many filters as required, in order to avoid returning an excessive number of records in the response.
You can also submit multiple values for each given filter. e.g. You can submit a filter for transactionreference values “23-9-1” and “23-9-2”, and any requests matching these values will be returned in the response. (We include an example of this case below)
TRANSACTIONQUERY request
For the TRANSACTIONQUERY request to be processed successfully, you need to submit at least one valid filter.
Request example
#!/usr/bin/python import securetrading stconfig = securetrading.Config() stconfig.username = "[email protected]" stconfig.password = "Password1^" st = securetrading.Api(stconfig) query = { "requesttypedescriptions": ["TRANSACTIONQUERY"], "filter":{ "sitereference": [{"value":"test_site12345"}], "currencyiso3a": [{"value":"GBP"}], "transactionreference": [{"value":"23-9-1"},{"value":"23-9-2"}] } } strequest = securetrading.Request() strequest.update(query) stresponse = st.process(strequest) #stresponse contains the transaction response

Field specification
The following table lists all fields that you can include in the filter when processing a TRANSACTIONQUERY request.
Note that although none of the following filter fields are required, at least one filter must be submitted for the request to be processed successfully. For this reason, all fields have been marked below as conditional.

TRANSACTIONQUERY response
Once you have successfully submitted a TRANSACTIONQUERY request, you will be returned a response that is divided into separate records.
Each record will contain a varying number of response fields, which depend on the request type indicated in the record. For example, if the record has a requesttypedescription of “AUTH“, then you would need to refer to the field specification in the Authorisation document.
Additionally, the response contains a field called found, which indicates the number of records that match the filters specified in the request. If found has a value of “0”, no records have been found using your specified filters.
For example, here is a simplified example of the structure of the response, consisting of 2 records (both are type “AUTH”):

A maximum of 500 records can be returned per response.
The found field will never return a value higher than 500, even if more than 500 requests meet the specified criteria.
Understanding errors
Please ensure you understand the Error Codes returned in the response:
- At the highest level of the response, along with transactionstartedtimestamp and found, there is an errorcode. This indicates whether or not the TRANSACTIONQUERY request was successful. If the error code here is not “0”, the TRANSACTIONQUERY request was not successful. You must address the problem and try again.
- In addition to this, each record will contain their own errorcode. This indicates whether or not the request represented in the record was successful.
- For a full list of error codes used by Trust Payments please click here.
Additional resources
Duplicate checks (API)
When enabled on your account, duplicate checks suspend transactions that are identical to previous transactions processed within the last 15 minutes. This is to automatically prevent assumed duplicate transactions (e.g. If the customer refreshes their browser and inadvertently sends two requests).
To enable duplicate checks on your account, please contact our Support team.
Managing transactions flagged as duplicates
When a transaction is suspended, its settlestatus is set to “2”, and the funds will not be settled into your bank account until you manually update the transaction. You can update the settlestatus to “1”, and this will instruct us to settle the pending transaction in the next settlement batch. Click here for information on settlement.
Emails informing of duplicates
When duplicates are flagged on your account, you will be informed using the email address you provided when you signed up with us. If you prefer, we can arrange these emails to be sent to a different address. Please contact our Support team for assistance.
Fraud checks (API)
Fraud rating
The fraud check analyses all transactions processed on your account and assigns a numerical fraud rating, which indicates the level of risk based on a number of pre-defined criteria.
- Before the fraud checks have been processed, the fraud rating will be “-1”.
- Following the processing of the fraud checks, a fraud rating of “0” indicates that no suspicious characteristics were detected.
- Every suspicious attribute found by the fraud checks will increment the fraud rating. A higher fraud rating indicates a higher likelihood of fraud.
- All transactions with a fraud rating of “2” or higher are collated into a daily email notification sent to the email address associated with your account.
- By default, we will suspend all transactions with a fraud rating of “5” of higher.
You can configure the thresholds that trigger these actions (e.g. in order to reduce the occurrences of false-positives) by contacting our Support team.
Reason codes
Trust Payments performs the following checks on authorised transactions in settlestatus “0” against records for the previous 7 days. If any of the following criteria are met, the fraud rating for the transaction will be incremented. A higher fraud rating indicates a greater chance of fraud, and as such transactions with high fraud ratings may be suspended in line with your Security Policy.
If matched, these criteria will raise the fraud rating:
The following increment the rating by 1:
- X – Same card number has been declined before with different expiry dates.
- E – Email address has been used with different declined cards or expiry dates.
- N – Cardholder name has been used with different declined cards or expiry dates.
- C – Card details are associated with a very high number of successful transactions.
- V – Cardholder name believed to be randomly-generated (e.g. “ghghghghg”).
- P – Postcode entered did not match that on the customer’s bank’s records.
The following increment the rating by 2:
- S – Security code entered did not match that on the customer’s card.
The following increment the rating by 10:
- G – Card number or billing address has been found in our negative database
The character on the left represents what we call the reason code. Following fraud checks, you can view which of the checks failed (if any), by matching the resulting reason codes with the list above. If any of the criteria are met, we will increment the fraud rating by the number shown above.
Viewing fraud rating and reason codes in MyST
You can view the fraud rating and reason codes (if any) for each transaction in MyST.
Transaction search
Select “Fraud rating” and “Fraud reason” in the optional “Fields” tab when performing a search on the “Transaction Search” page.
This allows you to compare fraud ratings/reasons of multiple transactions that meet your search criteria.
Single transaction view
The fraud rating and reason(s) are also visible in the single transaction view, as shown below.
Updating affected transactions
Sign in to MyST, search for the transaction and click “Update”. Modify the settlestatus of the transaction and click “Update”.
You can also update the settlestatus by submitting a TRANSACTIONUPDATE request.
Allowing transactions to settle
If you have manually investigated a transaction that has been flagged with a particular fraud rating and would like to instruct us to settle the transaction, you can manually override a transaction by updating the settlestatus to “1”. Settlement is performed once a day and all transactions with settlestatus “1” are settled regardless of their fraud rating.
Suspending transactions
If you believe a transaction to be suspicious but it has not been automatically suspended, you can manually suspend a transaction by updating the settlestatus to “2”. Suspended transactions can later be re-enabled for settlement by updating the settlestatus to “1” (as described above). They can also be permanently cancelled by updating the settlestatus to “3”.
Cancelling transactions
If you have manually investigated a suspended transaction and would like to cancel the payment, you can manually cancel a transaction by updating the settlestatus to “3”.
Cancelled transactions can never be settled by Trust Payments.
Negative database
Trust Payments’s internal negative database is a record of card numbers and billing email addresses previously associated with suspicious transactions.
When any transaction receives a fraud rating of “10” or higher, we will automatically add the card number and billing email address to the database.
When you process a transaction that includes a card number and/or billing email address that has been stored in the negative database, the fraud rating is increased by “10”, which immediately suspends the transaction under default configuration. (This requires fraud checks to be enabled on your account) If a transaction is suspended due to an entry in the negative database, it is shown with the reason code “G” in MyST.
Bypassing fraud checks
You can manually flag transactions to bypass the results of fraud checks by including a settlestatus of “1” in the payload submitted within your JWT.
3-D Secure (version 1)
If you are unsure, please contact our Support Team for assistance.
The following documentation explains how to manually perform 3-D Secure using version 1 through our Webservices API.
The process described below only supports 3-D Secure version 1.
We recommend all merchants utilise 3-D Secure version 2 by using our JavaScript Library.
If you are already processing e-commerce payments using our JavaScript Library, you do not need to follow the process described below, as the JavaScript Library will handle the 3-D Secure process automatically.
3-D Secure is a protocol designed to reduce fraud and chargebacks during e-commerce transactions. It allows Mastercard and Visa card issuers to provide an extra level of protection, by authenticating the customer’s identity at the point of sale, sometimes by prompting for a previously-agreed PIN and/or password.
Process overview
- Your system will need to send a THREEDQUERY request using our Webservices API (including the customer’s card details) and interpret the response returned.
- Trust Payments will check whether the customer’s card is enrolled in 3-D Secure.
If the customer is enrolled in 3-D Secure, your system will need to redirect the customer to the card issuer’s server (ACS URL) and handle the customer being redirected to your server (Term URL).
Your system will need to send an AUTH request using our Webservices API and interpret the response returned.
1. Check customer enrolment
To determine whether or not the customer’s card is enrolled in the 3-D Secure scheme, you need to manually submit a THREEDQUERY request using our Webservices API.
THREEDQUERY Request
The following example demonstrates how to structure a THREEDQUERY request:
#!/usr/bin/python import securetrading stconfig = securetrading.Config() stconfig.username = "[email protected]" stconfig.password = "Password1^" st = securetrading.Api(stconfig) threedquery= { "termurl":"https://termurl.com", "accept":"text/html,*/*", "pan": "4111111111111111", "expirydate": "12/2020", "securitycode": "123", "currencyiso3a":"GBP", "requesttypedescriptions": ["THREEDQUERY"], "accounttypedescription":"ECOM", "sitereference": "test_site12345", "baseamount": "1050" } strequest = securetrading.Request() strequest.update(threedquery) stresponse = st.process(strequest) #stresponse contains the transaction response
<?php
if (!($autoload = realpath(__DIR__ . '/../../../autoload.php')) && !($autoload = realpath(__DIR__ . '/../vendor/autoload.php'))) {
throw new Exception('Composer autoloader file could not be found.');
}
require_once($autoload);
$configData = array(
'username' => '[email protected]',
'password' => 'Password1^',
);
$requestData = array(
'termurl' => 'https://termurl.com',
'accept' => 'text/html,*/*',
'pan' => '4111111111111111',
'expirydate' => '12/2020',
'securitycode' => '123',
'currencyiso3a' => 'GBP',
'requesttypedescriptions' => array('THREEDQUERY'),
'accounttypedescription' => 'ECOM',
'sitereference' => 'test_site12345',
'baseamount' => '1050'
);
$api = \Securetrading\api($configData);
$response = $api->process($requestData);
var_dump($response->toArray());
?>
curl --user [email protected]:Password1^ https://webservices.securetrading.net/json/ -H "Content-type: application/json" -H "Accept: application/json" -X POST -d '{ "alias": "[email protected]", "version": "1.00", "request": [{ "termurl":"https://termurl.com", "accept":"text/html,*/*", "pan": "4111111111111111", "expirydate": "12/2020", "securitycode": "123", "currencyiso3a":"GBP", "requesttypedescriptions": ["THREEDQUERY"], "accounttypedescription":"ECOM", "sitereference": "test_site12345", "baseamount": "1050" }]}'
Here is the specification of the fields included in the THREEDQUERY request described above:
Key
| Field name | Type | Length | Request | Description |
| accept | Alphanumeric | 1024 |  |
The exact content of the HTTP accept-header field as received from the cardholder’s user agent. |
| accounttypedescription | Alpha | 20 | |
This must be submitted as “ECOM” (e-commerce). |
| baseamount | Numeric | 13 | |
The amount of the transaction in base units, with no commas or decimal points, so £10 is submitted as 1000. This value must be greater than zero. (Max length may vary depending on your acquiring bank – Contact your bank for further info) |
| currencyiso3a | Alpha | 3 | |
The currency that the transaction will be processed in. |
| expirydate | Date MM/YYYY | 7 | |
The expiration date printed on the card. |
| pan |
Numeric | 12-19 | |
This is the long number printed on the front of the customer’s card.
We return a masked version of this PAN in the response, in the field maskedpan. e.g. “411111######1111” |
| requesttypedescriptions | Alpha | 20 | |
The request type required is “THREEDQUERY”. |
| securitycode |
Numeric | 3-4 | |
This is the three digit security code printed on the back of the card. (For AMEX cards, this is a 4 digit code found on the front of the card)This field is not strictly required field by Trust Payments, but it is highly recommended for the processing of security code checks.Additionally, some banks may decline the payment if the security code is not present. |
| sitereference | Alphanumeric including underscore |
50 | |
The site reference relates to your individual account which you received on setup. If you do not know your site reference, please contact our Support team. |
| termurl | URL | 1024
More info |
|
This field value is a URL of a script/file located on your system that is able to manage customers who are returned to your system. It is used to instruct the card issuer where to send the customer’s browser after they have been authenticated on the card issuer’s ACS. |
| useragent | Alphanumeric | 255 |  |
The exact content of the HTTP user-agent header field as received from the cardholder’s user agent. We strongly recommend you submit this field, as failure to do so may forfeit the liability shift. |

Check the error code field value
If the errorcode value returned in the response is not ‘0’, an error has occurred. If an errorcode other than ‘0’ is returned, please consult the table below and attempt to resolve the issue:
| Error code | Description |
| 0 | Request was successful. |
| 30000 | Invalid field. |
| 60031 | The THREEDQUERY request used a payment type that is not supported by Trust Payments 3-D Secure. |
| other | Other errors will require further investigation. Click here for a full list of possible error codes. |
If you were unable to resolve the issue, you can instruct your system to perform a standard AUTH without using 3-D Secure.
Check the enrolled field value
If the enrolled value returned in the response is “Y”, the customer’s card is enrolled in 3-D secure. Please refer to the following table for enrolled values:
| Enrolled | Description | Action |
| Y | The card is enrolled in the card issuer’s 3-D Secure scheme. | Send the customer to the card issuer’s Access Control Server (ACS). The URL for the ACS is provided in the acsurl of the THREEDQUERY response. |
| N | The card is not enrolled in the card issuer’s 3-D Secure scheme. | Perform an AUTH Request, including the transactionreference returned in the THREEDQUERY response (example can be found below). |
| U | The card’s enrolment in the card issuer’s 3-D Secure scheme could not be determined. | This typically indicates a temporary problem with the card issuer’s systems. You can configure your system to resubmit the same THREEDQUERY request. If this continues to fail, submit a standard AUTH request using our Webservices API, including the transactionreference returned in the THREEDQUERY response. |
Here is the specification of the fields included in the THREEDQUERY response described above:
Key
| Field name | Type | Length | Response | Description |
| requesttypedescription | Alpha | 20 | |
“THREEDQUERY” is always returned in the response. |
| xid | Alphanumeric | 255 | |
The unique identifier for the transaction, assigned by the MPI (Merchant Plug-In) (in this case, Trust Payments). |
| enrolled | Char | 1 | |
Determines if the cardholder is enrolled in a 3-D Secure scheme.
|
| pareq | Alphanumeric including symbols | 2048 | |
The unique identifier for the transaction, assigned by the MPI (Merchant Plug-In) (in this case, Trust Payments). |
| md | Alphanumeric including symbols | 1024 |  |
Returned if card is enrolled.
The unique 3-D Secure reference for this transaction. |
| acsurl | URL | 1024 | |
Returned if card is enrolled.
The URL of the Access Control Server (ACS) to be used in authenticating the cardholder. |
| threedversion | Numeric | 6 | |
Only returned for accounts with certain acquiring banks.
The version of the 3-D Secure protocol. |
Your progress
Following the instructions above, your system should now be able to determine whether or not a customer’s card is enrolled in a 3-D Secure scheme. If the customer’s card is enrolled, follow the “Authenticate the customer” section below, otherwise skip ahead to the “Authorisation” section.
2. Authenticate the customer
If the card is not enrolled, skip ahead to the “Authorisation” section.
If the customer is enrolled in the card issuer’s 3-D Secure scheme, your system must send the customer’s browser to the card issuer-hosted Access Control Server (ACS) using an HTTPS POST. The URL for the ACS can be found in the acsurl field of the THREEDQUERY response.
On the ACS, the customer will be authenticated, sometimes by prompting for a previously-agreed PIN and/or password. The browser must send data from the termurl, pareq and md in HTML fields ‘TermUrl’, ‘PaReq’ and ‘MD’, respectively (These field names are case sensitive).
Following authentication, the customer will be returned to your servers using an HTTPS POST. You will need to parse this response, as it will contain the ‘PaRes’ and ‘MD’ fields, for constructing the subsequent AUTH Request needed to process the payment.
The following is an example of how to redirect the cardholder to the card issuer’s ACS :
<!DOCTYPE html PUBLIC '-//W3C//DTD HTML 4.01//EN'>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
<title>Processing payment</title>
<style type="text/css">
h3,h3,h4 { font-family: verdana, arial, sans-serif;
font-weight: normal;}
#logo {float: left;}
</style>
</head>
<body OnLoad="document.form.submit();" >
<form name="form" id="form" action="$acsurl" method="POST">
<div>
<input type="hidden" name="PaReq" value="$pareq" />
<input type="hidden" name="TermUrl" value="$termurl" />
<input type="hidden" name="MD" value="$md" />
</div>
<noscript>
<div>
<h3>JavaScript is currently disabled or is not supported by your browser.</h3>
<h4>Please click Submit to continue processing your 3-D Secure transaction.</h4>
<input type="submit" value="Submit">
</div>
</noscript>
</form>
</body>
</html>
Referencing 3-D Secure transactions
In most circumstances, your system will need to store data about the transaction in your database while the customer is being authenticated on the card issuer’s ACS, to be retrieved when the customer returns to your system via the termurl. As the 3-D Secure specification requires that only the md and pares fields are returned to your system, it is recommended that the md field is used to look up any corresponding customer session to complete the transaction.
Waiting for the customer to return from the ACS
Your system will need to consider the length of time it may take for the customer to enter their details on the card issuer’s ACS. The time the customer will spend on the ACS will depend on a number of factors. Longer wait times may occur when the customer is signing up to a 3-D Secure scheme for the first time, or recovering a forgotten password. While your system needs to allow time for the customer to return, it is entirely possible for the customer to close their browser on the card issuer’s ACS and not return at all. There are no specific regulations as to how long your system must wait for the customer to be redirected from the ACS to your Term URL, but we recommend waiting for no more than two hours.
Your progress
Following the instructions above, your system should now be able to redirect the browsers of customers with cards enrolled in a 3-D Secure scheme to the ACS for authentication. Your system can now proceed and submit an AUTH request using our Webservices API to process the payment, by following the instructions below.
3. Authorisation
3-D authorisations are used to seek authorisation for authenticated transactions from your acquiring bank. This is performed by manually submitting an AUTH Request using our Webservices API and interpreting the response returned.
AUTH Request
For enrolled cards only
The following example demonstrates how to structure a 3-D AUTH request when the card is enrolled in a 3-D Secure scheme:
#!/usr/bin/python import securetrading stconfig = securetrading.Config() stconfig.username = "[email protected]" stconfig.password = "Password1^" st = securetrading.Api(stconfig) auth= { "requesttypedescriptions": ["AUTH"], "md":"UEZOVVBqeE5SRDQ4VFVSSVBrRjVXSGhOZFZReVUzVlalBVeE", "pares":"eJzVWFmzosgSfudXdPQ8Gt1sbkzYRhQ7KCjI/sYOsimgoL/+lp7Tp5" } strequest = securetrading.Request() strequest.update(auth) stresponse = st.process(strequest) #stresponse contains the transaction response
<?php
if (!($autoload = realpath(__DIR__ . '/../../../autoload.php')) && !($autoload = realpath(__DIR__ . '/../vendor/autoload.php'))) {
throw new Exception('Composer autoloader file could not be found.');
}
require_once($autoload);
$configData = array(
'username' => '[email protected]',
'password' => 'Password1^',
);
$requestData = array(
'requesttypedescriptions' => array('AUTH'),
'md' => 'UEZOVVBqeE5SRDQ4VFVSSVBtSllOVTlMYVdaUlJXWnZVRTA0UVdwVlJXZFpRo5cEk9',
'pares' => 'eJztWEnTqsi2nfMrKqqGxik6UajwJFCOxLb5BNvgHdPneIihB/fq2eNv777/BdaScGg='
);
$api = \Securetrading\api($configData);
$response = $api->process($requestData);
var_dump($response->toArray());
?>
curl --user [email protected]:Password1^ https://webservices.securetrading.net/json/ -H "Content-type: application/json" -H "Accept: application/json" -X POST -d '{ "alias": "[email protected]", "version": "1.00", "request": [{ "requesttypedescriptions": ["AUTH"], "md":"UEZOVVBqeE5SRDVS1FLVG9aenQrRGhaNk1NPQ==", "pares":"eJztWMmyq7iynfMVFVVDxyk6Y0OX0U1wTQ==" }]}'
For non-enrolled cards only
For cards that are NOT enrolled in the card issuer’s 3-D Secure scheme (or have unknown enrolment), you will need to submit the following fields in order to inherit transaction information needed to perform the authorisation:
#!/usr/bin/python import securetrading stconfig = securetrading.Config() stconfig.username = "[email protected]" stconfig.password = "Password1^" st = securetrading.Api(stconfig) auth= { "requesttypedescriptions": ["AUTH"], "sitereference": "test_site12345", "parenttransactionreference": "1-2-345678" } strequest = securetrading.Request() strequest.update(auth) stresponse = st.process(strequest) #stresponse contains the transaction response
<?php
if (!($autoload = realpath(__DIR__ . '/../../../autoload.php')) && !($autoload = realpath(__DIR__ . '/../vendor/autoload.php'))) {
throw new Exception('Composer autoloader file could not be found.');
}
require_once($autoload);
$configData = array(
'username' => '[email protected]',
'password' => 'Password1^',
);
$requestData = array(
'requesttypedescriptions' => array('AUTH'),
'sitereference' => 'test_site12345',
'parenttransactionreference' => '1-2-345678'
);
$api = \Securetrading\api($configData);
$response = $api->process($requestData);
var_dump($response->toArray());
?>
curl --user [email protected]:Password1^ https://webservices.securetrading.net/json/ -H "Content-type: application/json" -H "Accept: application/json" -X POST -d '{ "alias": "[email protected]", "version": "1.00", "request": [{ "requesttypedescriptions": ["AUTH"], "sitereference": "test_site12345", "parenttransactionreference": "1-2-345678" }]}'
Inheritance
The example AUTH requests shown above (both enrolled and not-enrolled) contain all the fields that are required for submission. All other information required to seek authorisation will be inherited from the previous THREEDQUERY request stored on our system.
We allow the submission of additional fields in the AUTH request that have not been submitted in the THREEDQUERY request (e.g. the customer name, if omitted in the query).
Click here for a full list of fields that can be submitted in an AUTH request.
Here is the specification of the fields included in the AUTH requests described above:
Key
| Field name | Type | Length | Request | Description |
| pares | Alphanumeric including symbols | 1024 | |
Only send if card is enrolled.
Must be the value returned in the pares field of the HTTPS POST from the card issuer’s ACS, otherwise this may forfeit the liability shift. |
| md | Alphanumeric including symbols | 65536 | |
Only send if card is enrolled.
The unique 3-D Secure reference for this transaction. Supplied if enrolled is “Y” |
| parenttransactionreference | Alphanumeric including hyphens | 25 | |
Only send if card is NOT enrolled.
Unique reference of the parent THREEDQUERY request. |
| sitereference | Alphanumeric including underscore | 50 | |
Only send if card is NOT enrolled.
The site reference processing the transaction. |
AUTH Response
The data returned in the AUTH response will depend on both the card enrollment status, and whether or not the customer was successfully authenticated on the card issuer’s ACS.
Your system should be able to interpret the response data in each of the following scenarios.

Managing authorisation response
Your system will need to interpret the AUTH response in order to determine if the transaction was successful. The most important field to check in the response is the errorcode.
| Error code | Description |
| 0 | Cardholder was successfully authenticated on the card issuer’s ACS. Customer’s bank authorised the transaction. Funds will be transferred. |
| 70000 | Cardholder was successfully authenticated on the card issuer’s ACS. Customer’s bank declined the transaction. Funds will NOT be transferred. |
| 60022 | Cardholder was NOT successfully authenticated on the card issuer’s ACS. Trust Payments did not contact the acquiring bank to seek authorisation. Funds will NOT be transferred. |
| 99999 | An error code of ‘99999’ indicates an unknown error occurred, which requires manual inspection. We recommend contacting our Support Team for assistance, providing a copy of the entire request submitted and the response returned. In the interest of security, ensure you omit or mask sensitive field values, such as card details. |

AVS and security code checks
The Address Verification System and security code checks provide you with a further level of security to a transaction, allowing additional checks regarding the validity of the address and security code information supplied by the customer.
Introduction to AVS
A customer’s address is checked against the address that the card issuer holds for that card. The issuing bank will indicate to the acquiring bank whether there is a match between the entered address and the registered card address. The checks performed are focused on the house number and postcode provided by the customer.
Introduction to security code checks
The security code is a three or four digit number printed on credit and debit cards. It is not stored by Trust Payments, and also must never be stored by merchants.
The number is often printed on the back of the card, on the signature strip.
Alternatively, on American Express cards the security code can be found on the front of the card, on the right–hand side, above the embossed card number.
Process overview
Here is how the AVS and security code checks fit into the standard payment process:
Depending on your account configuration, Trust Payments may perform certain actions on the transaction if the results of the AVS and security code checks do not meet a required standard. This behaviour is configured as part of your security policy (scroll down for further information on the security policy).
Requirements
Supported cards and banks
The availability of the AVS and security code check facility is dependent on the acquiring bank and card issuer, although it should be noted that most cards support this functionality.
The ability to conduct address checks is dependent on the location of your acquiring bank in relation to the location of the issuing bank of the card being presented. Most acquirers do support the process but only on locally issued cards. All UK cards and a number of US cards are address checked by all UK acquirers.
Security code checks are performed on all Visa, Mastercard and American Express branded cards worldwide and the results are checked internationally by all acquirers.
Please contact our Support team for further information on supported acquirers and card types.
Required fields
For checks to be successfully performed on the customer’s details, the customer will need to provide their billing postcode, billing premise and their card’s security code.
If this information is not present in the request to Trust Payments, we will return a “Not given” response.
Response codes
There are four different possible responses following AVS and security code checks. Each response is assigned a distinct code, as shown in the following table:
| Code | Description | Comment |
| 0 | “Not given” | Your acquirer was not provided with the information required to perform this check. |
| 1 | “Not checked” | Your acquirer was unable to perform checks on the information provided. |
| 2 | “Matched” | The information provided by the customer matches that on the card issuer’s records. |
| 4 | “Not matched” | The information provided by the customer does NOT match that on the card issuer’s records. |
Together, the AVS and security code checks consist of three total checks, and we assign a response code for each:
- Card security code
- Billing postcode
- Billing premise
Security policy
Your account’s security policy consists of preferences on how we respond to instances where the address (premise & postcode) and security code entered by the customer does not directly match those found on the card issuer’s records. We can automatically suspend transactions that return certain response codes:
To discuss or make changes to your security policy, please contact the Support team.
You can perform AVS and security code checks without debiting the customer. This is achieved by performing an Account Check. Click here to learn more about Account Checks.
