Authorisations

The following documentation explains how to manually submit an AUTH request using our Webservices API.

If you are already processing e-commerce payments using our JavaScript Library (using 3-D Secure v2), you no longer need to manually perform the AUTH request described herein (as the JavaScript Library will automatically perform the authorisation).

This page is written for those processing Mail or Telephone Order (MOTO) payments, Merchant Initiated Transactions (MIT), or other advanced workflows that do not warrant 3-D Secure v2 being enabled.

Requirements

The following content assumes you have obtained the necessary PCI certification to process and submit sensitive cardholder data in the request to our Webservices API.

If you are unsure, please contact our Support Team for assistance.

All businesses within the EEA (European Economic Area) will soon be mandated to use 3-D Secure when processing e-commerce transactions, as part of the PSD2 mandate.

To perform 3-D Secure, you will need to utilise our JavaScript Library. Click here to get started.

ECOM (e-Commerce) Maestro transactions require the implementation of 3-D Secure in order to be processed successfully.

To perform 3-D Secure, you will need to utilise our JavaScript Library. Click here to get started.

In order to reduce fraud, Visa has mandated that all UK-based merchants with a Merchant Category Code (MCC) of 6012 are required to send additional fields in AUTH and ACCOUNTCHECK requests.

Failure to submit these fields may prevent the transaction from being processed successfully, with a “60025” errorcode being returned in the response.

secrand	Alphanumeric (16)	Random string of characters, returned in the response of non-API-based libraries developed by Trust Payments.

Tokenisation from previous request

To submit subsequent transactions with the same details, your system can process another AUTH request, and reference the previously-completed payment’s transactionreference, which is returned in the response. Submit this reference in the parenttransactionreference field of the new AUTH request, and the majority of fields (card details, billing address, delivery address, order reference, etc.) will be re-used when proceeding with the new payment. Please refer to the following example request:

MyBank

The requests outlined in this document will need to be processed manually using our Webservices API.

MyBank is a real-time bank transfer system that operates in Italy. When processing a payment with MyBank, customers will be prompted to select their bank and then to sign in to their online banking account. After reviewing the pre-filled payment details, they can agree to the payment, before being redirected back to your website. Once completed, you will receive confirmation via a URL notification.

Features

Supported customer countries	IT
Supported currencies	EUR
Protect Plus	Supported.
Refunds	Full refunds supported (permitted for up to 365 days).
Chargebacks	Payments are not subject to chargebacks.

Configuration

To enable MyBank on your account, please get in touch with your account manager.
A test sandbox account will be provided, which you will need when testing your implementation.

Process overview

Initiate the customer

Customer agrees to a payment using MyBank on the merchant’s website.
Merchant submits AUTH request to initiate the session, including the successfulurlredirect and errorurlredirect.
Merchant receives AUTH response, including redirecturl.

Redirect to MyBank

Merchant redirects the customer’s browser to the redirecturl.
Customer follows instructions on MyBank’s hosted pages to authorise the payment.
If successful, the browser is redirected to the successfulurlredirect, a page hosted by the merchant that displays confirmation of payment.
If there has been a problem with the payment, the browser is redirected to the errorurlredirect, a page hosted by the merchant that displays an error to the customer.

Payment completion

At a later time, MyBank will contact Trust Payments with confirmation that funds have been settled.
Trust Payments will submit a URL notification to the merchant’s system to confirm funds have settled.
Merchant receives the notification and responds to inform Trust Payments the notification was received successfully.

1. Initiate the customer

When the customer chooses to pay with MyBank, your system will need to perform an AUTH request and, if successful, redirect the customer’s browser to the URL returned in the response.

Handling the response

The settlestatus returned in the AUTH response is used to determine the status of the MyBank payment:

If the settlestatus is “10”, the payment is pending settlement.

The funds have not yet been settled into your bank account.
The next step is to redirect the customer’s browser to the redirecturl to complete the payment.

Funds will not be settled into your account until the customer is redirected to MyBank’s pages, in order to complete the payment. Read on for further information.

When there is an update to the settle status of the AUTH, you will receive a URL notification to inform you that the settlestatus has been updated to either “3” or “100”.
Further information on the notifications can be found below.

If the settlestatus is “3”, the payment has been cancelled.

The payment has been declined, or has encountered an error.
To learn more about why the payment was unsuccessful, you will need to look at the errorcode. e.g. “70000” indicates that the payment was declined. Click here for a full list of error codes.

In addition to the above, we also recommend following our Best practices.

2. Redirect to MyBank

Your system will need to redirect the customer’s browser to the redirecturl, which is a page hosted by MyBank, in order to process the payment. At a later time, the customer will be redirected back to either the successfulurlredirect or the errorurlredirect provided in the AUTH request.

If the customer is redirected to the successfulurlredirect:
The customer successfully completed the required steps on MyBank’s pages.
Recommended actions: Display confirmation that the payment was successful.

If the customer is redirected to the errorurlredirect:
The customer encountered a problem that has prevented them from completing the payment.
Recommended actions: Inform the customer that there was a problem with the payment, displaying sufficient transaction details for the customer to query the payment attempt.

When testing, you will be displayed the sandbox as provided by MyBank. To complete a test transaction, you will need to follow the instructions displayed on screen. Please contact your account manager for test credentials to enter while on the sandbox.

3. Payment completion

Once the customer returns from the MyBank hosted page to either the successfulurlredirect or errorurlredirect hosted on your site, you will need to display either a confirmation or error message respectively.

The settlement process for MyBank differs from the standard process followed with card-based payment methods.

Once a payment has been authorised, funds will be settled at a later time, as determined by MyBank.

The settlement notification may not be sent immediately after processing the AUTH.

In the unlikely event that payment is still pending settlement after 7 days (settlestatus “10”), this will be scheduled for investigation and we will contact you with further information.

Before you begin testing, we recommend that you contact our Support team and request that rules are enabled on your account, which submit URL notifications to your system in the following scenarios:

When a payment is authorised.
When funds have been settled.

Configuring the authorisation notification

We recommend including at least the following fields in your authorisation notification:

Acquirer Response Message (acquirerresponsemessage)
Base Amount (baseamount) (e.g. £10.50 is “1050”)*
Main Amount (mainamount) (e.g. £10.50 is “10.50”)*
Billing Country (billingcountryiso2a)
Currency (currencyiso3a)
Error Code (errorcode)
Live Status (livestatus)
Order Reference (orderreference)
Payment Type (paymenttypedescription)
Request Type (requesttypedescription)
Settle Status (settlestatus)
Site Reference (sitereference)
Transaction Reference (transactionreference)
Transaction Started Timestamp (transactionstartedtimestamp)

*Please choose your preferred format.

Configuring the settlement notification

We recommend including the following fields in your settlement notification:

Settle Status (settlestatus)
Site Reference (sitereference)
Transaction Reference (transactionreference)

Check the notification

You will need to check the contents of each notification received and respond accordingly by following the processes outlined in the “URL notifications” section of our Action types page. In particular, you will need to look at the updated settlestatus value:

On authorisation: If the settlestatus is “0”, “1” or “10”, the payment has been authorised and you are not required to take further action at this time. However, values of “2” or “3” indicate funds are not scheduled for settlement (suspended and cancelled, respectively).
On settlement: If the settlestatus has been updated to “100”, this indicates that the funds have been settled. Alternatively, if this has been updated to “3”, this indicates there has been a problem and the payment was subsequently cancelled.

Cancelled transactions (settlestatus “3”) may be settled at a later time. In situations where the customer has completed the steps required to fulfil the payment, the settlestatus is updated to “100” to indicate the funds have been transferred to your account.

If you have contacted the Support Team to configure settlement notifications (as described above), you will be notified when this occurs.

Testing

You will need to test your solution before you can begin processing live payments. Test transactions are processed through your test Site Reference.

Requirements

You will need to contact our Support team, providing your MyBank test account details. We will then configure your test site reference to connect directly to the MyBank testing environment.

When performing test transactions, the redirect URL returned in the AUTH response will redirect your browser to the MyBank testing environment to simulate a payment. Other than this, the process will be exactly the same as processing live payments.

Refunds

After processing a payment with MyBank, it is possible to pay the customer back by submitting a REFUND request.

Refunds for MyBank are settled immediately (settlestatus “100”).

Requirements

You cannot refund a payment until the AUTH has been settled (settlestatus is “100”).
You cannot refund a greater amount than was originally settled.
Partial refunds are not supported for MyBank payments.

The REFUND request and response for MyBank payments follow the same field specification as outlined in our standard REFUND documentation. Click here for further information.

Testing

Use the credentials provided on this page to test your solution.

When you sign up, you will be provided with a “live” account and a “test” account (the latter is prefixed with “test_”).
When testing, ensure requests submitted to Trust Payments reference your test sitereference.

It is important to thoroughly test your integration using your test sitereference before processing live payments.

Before you begin testing…

Please be aware of the following notes:

Most fields submitted to our test system will be accepted. Any data breaching its defined specification will return an error message.

Any test data that generates a successful response when submitted while a merchant is in test mode, will produce a declined response when a merchant is switched into live mode. In some cases, the test data may return an error response.

Our test system attempts to simulate responses in a similar fashion to the live system. However, depending on your acquirer you may find some responses differ slightly from those given by the test system.

In the interest of security, we recommend against using real payment details when using your test account.

We recommend specifying the main amount “10.50” when testing. Other amounts can be used but may return unexpected responses.

If you’re unsure where to start with your testing, you may find these resources helpful:
- Payment Pages integrations
- JavaScript Library integrations

Test card details

The table below lists test card numbers and customer information that can be submitted to our test bank, along with the responses that should be expected in return.

Do not use these credentials when processing transactions on your live site reference.

While testing, all card types are supported, but when using your live account, you will receive an error if you do not have a valid merchant number for the payment type submitted.

A baseamount of 70000 (£700.00) will always return a declined response from the test bank.
A baseamount of 60010 (£600.10) will always return a bank system error from the test bank.
Using baseamount 1050 (£10.50) will not generate an error.

3-D Secure status testing

To test for different 3-D Secure status values, follow the instructions displayed in the authentication prompt shown on the page (an example is shown below). In the textbox provided, you can enter different PIN values to test for different cases.

Displaying the test ACS page

For Payment Pages:

With 3-D Secure enabled on your site reference, process a payment using one of the card numbers listed above and your browser will display an authentication prompt with instructions.

For JavaScript library implementations:

After your payment form has been updated to reference our JavaScript library, process a payment using one of the card numbers listed above and your browser will display an authentication prompt with instructions.

The authentication prompt will only be displayed for non-frictionless test card details.

Frictionless cards will bypass authentication. In this case, the payment will be processed immediately (without being prompted by the browser for information).

Follow the instructions displayed within the authentication prompt to complete the payment:

Non 3-D Secure

The following card types are not currently processed using 3-D Secure (a form of SCA):

Card type	Authorisation	Decline	Expiry date	Security code
DINERS	3000000000000111	3000000000000012	12/2030	123
DISCOVER	6011000000000301	6011000000000202	12/2030	123
JCB	3528000000000411	3528000000000312	12/2030	123

After the payment has been processed, the error code and status values stored with the processed AUTH are used to convey the final outcome.

When the status is “N”, indicating the customer failed authentication, the errorcode “60022” will be returned.

Testing AVS and security code checks

If you haven’t already, please read our AVS and Security code documentation before testing:
Link to Payment Pages docs / Link to API docs

The following tables list test details that can be submitted to obtain different responses from the AVS and Security Code Checks. These details can be used with most major payment types.

Only the billing premise, billing postcode and security code field values dictate the outcome of the AVS and security code checks performed. As such, entering any details into the other address fields will not affect the outcome of these checks.

Link to Payment Pages docs / Link to API docs

Testing recurring payments

Testing for the acquirer advice code

When processing recurring payments, some acquirers may return an acquirer advice code in the response. The acquirer advice code is a numeric value used to indicate if further recurring payments can be processed for the given card.

Code	Description	Action
0	N/A	No action required
1	New account information available (Mastercard only)	Query customer for updated payment details
2	Cannot approve at this time	Try again later. If you are continuing to have difficulties, please contact your acquiring bank
4	Do not try again	Do not process further recurring transactions
8	Payment blocked by card scheme	Do not process further recurring transactions

Where to find the acquirer advice code

This code is returned in your daily subscription email report.
It’s viewable within MyST by selecting the additional field to be displayed on the transaction search page. It can also be viewed on the single transaction view.
Additionally, for those who have processed a recurring AUTH transaction using the API, the code is returned in the acquireradvicecode field in the response.

How to test for different acquirer advice codes

You can test that your system responds appropriately to different acquirer advice codes by processing transactions with the following attributes:

Visa
Acquirer advice code returned	Card number	Base amount
0	4111111111111111	1050
2	4000000000000671	1002
4	4000000000000671	1004
8	4000000000000671	1008

Acquirer advice code ‘1’ can only be returned for recurring Mastercard transactions.

Mastercard
Acquirer advice code returned	Card number	Base amount
0	5100000000000511	1050
1	5100000000000271	1001
2	5100000000000271	1002
4	5100000000000271	1004
8	5100000000000271	1008

Testing Protect Plus

If you haven’t already, please read our Protect Plus document before testing:
Link to Payment Pages docs / Link to API docs

Use the following baseamount values in RISKDEC requests to simulate the different possible responses from the Protect Plus checks:

baseamount	Possible fraudcontrolresponsecode returned	fraudcontrolshieldstatuscode returned
1011, 2011, 3011	0100, 0150	“ACCEPT”
1033, 2033, 3033	0300, 0330, 0500	“CHALLENGE”
1044, 2044, 3044	0250, 0400, 0600, 0700, 0800, 1300	“DENY”

The fraudcontrolshieldstatuscode and fraudcontrolresponsecode values returned in RISKDEC responses may vary when not using the baseamount values listed in the table, above.

Testing DCC

If you haven’t already, please read our DCC document before testing:
Link to Payment Pages docs / Link to API docs

The card numbers listed in this test section are associated with specific local currencies. During your integration, you can use the following international test card details in order to test your system for successful and declined DCC transactions.

Successful authorisations

Country code	Currency code	Visa Credit	Mastercard Credit
DE	EUR	4500000000000007	5500000000000004
GB	GBP	4300000000002211	5311110000001511

US	USD	4900460000002492	5590470000002402

You can also use an amount of 70000 in the final currency to generate a decline response.

Settlement

The following procedure applies to card-based payment methods. Please be aware that the settlement process for certain APMs (Alternative Payment Methods) may deviate from the below. For this reason it is important that you read the relevant documentation when adding APMs to your solution.

Once a transaction has been authorised, the funds are then reserved against the customer’s account for 7 days. The instruction to transfer the funds is scheduled daily when we submit a batch of all pending transactions to your acquirer.

This process is called settlement and is outlined below:

The initial phase of the settlement process occurs when we submit a file to your acquirer. The file contains all transactions that are in status ‘pending settlement’, and this occurs daily.

When your acquirer has received the settlement file, they commence the process of physically settling the money into your nominated bank account. The time frame of this payment differs between banks, and is not determined by Trust Payments. If reserved funds are not settled, they are released back onto the customer’s card. We recommend that you regularly sign in to MyST to check the status of your payments.

Deferred settlement

Settlement can be deferred for certain transactions. You can request this by modifying the payment request, or transactions may be deferred by our internal fraud system. You should therefore sign in to MyST on a regular basis, to check the status of your transactions.

Settle status

Settle status 0 – Pending settlement

Transaction that has been authorised by card issuer for payment.

Settles automatically.
Can be updated or cancelled.
Does not currently require action from the merchant.
May be suspended by future Fraud checks and Duplicate checks, if enabled.

Settle status 1 – Pending settlement (manual override)

Transaction that has been authorised by card issuer for payment.

Settles automatically.
Can be updated or cancelled.
Does not require further action from merchant.
Bypasses fraud and duplicate checks, if enabled.

Settle status 10 – Settling

Details of this transaction have been sent to the acquiring bank for settlement.

Does not require further action from merchant.
Settles automatically.
Cannot be updated or cancelled.

Settle status 100 – Settled

Transaction has been settled into the merchant’s account.

Does not require further action from merchant.
Cannot be updated or cancelled.
Can be refunded (unless all funds have already been refunded).

Settle status 2 – Suspended

Transaction has been suspended, and will not settle without action from the merchant.

Transactions can be suspended by merchants to prevent settlement, allowing for manual investigation.
Transactions can be suspended by Trust Payments if fraud or duplicate checks (if enabled) raise an issue.
If left in a suspended state for 7 days after the authorisation date, the transaction will be cancelled automatically (updated to settle status ‘3’). This limit is extended to 31 days for pre-authorisations.
The merchant can update transactions in settle status ‘2’ to the following states:
‘0’ – Allows settlement to occur, providing the transaction passes fraud checks.
‘1’ – Allows settlement to occur, bypassing fraud checks.
‘3’ – Manually cancels the transaction.

Settle status 3 – Cancelled

Transaction has been cancelled and will not settle.

This can be due to an error or due to the transaction being declined.
If a transaction is left in a suspended state (settle status ‘2’) for 7 days after the authorisation date, the transaction will be cancelled automatically. This limit is extended to 31 days for pre-authorisations.
Merchants can also manually update transactions to settle status to ‘3’ to cancel them.
Cancelled transactions cannot be updated.

3-D Secure (version 1)

The following content assumes you have obtained the necessary PCI certification to process and submit sensitive cardholder data in the request to our Webservices API.

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.

For a fully authenticated 3-D Secure transaction, in the event of a dispute at a later date the card issuer will usually take responsibility of the chargeback instead of the merchant. The liability issues involved with 3-D Secure transactions can be found in this FAQ.

Process overview

Check customer enrolment

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.

Authenticate the customer

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).

Authorisation

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:

PYTHON
PHP
CURL

#!/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',

  '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 '{

}]}'

Here is the specification of the fields included in the THREEDQUERY request described above:

When reading the field specifications included on this page, please ensure that you reference the relevant code examples for your chosen language.

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. Click here for a full list of available currencies.
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.

THREEDQUERY Response

This section documents how to interpret a THREEDQUERY response, which is used to indicate whether or not the customer’s card is enrolled in the card issuer’s 3-D Secure scheme.

The acsurl, md and pareq fields are only returned in a THREEDQUERY response for enrolled cards.

The md and pareq typically contain values far longer than displayed in the example above and therefore have been abbreviated, for your convenience.

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.

When performing an AUTH request without 3-D Secure, this will result in forfeiting the liability shift.

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. “Y” – Card is enrolled. “N” – Card is not enrolled. “U” – Unable to determine if card is enrolled.
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

Only attempt to authenticate the customer if their card is confirmed to be enrolled in a 3-D Secure scheme.

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).

The size of the ACS page displayed in the customer’s browser is controlled by the ACS provider (cannot be modified by merchants or Trust Payments). As a guideline, Visa and Mastercard both state that the Verified by Visa authentication window should be 390×400 pixels in size

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.

When the customer’s browser is redirected to your server from the ACS, please be aware that some ACS will also include a field called “realPan”, which contains the customer’s card number in plain text. It is imperative that you do not store the value of realPan on your own server.

The following is an example of how to redirect the cardholder to the card issuer’s ACS :

</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:

PYTHON
PHP
CURL

#!/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=="
}]}'

The md and pares fields typically contain values far longer than displayed in the example above and therefore have been abbreviated for your convenience. When submitting these fields, your system must submit their full values, unmodified.

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:

PYTHON
PHP
CURL

#!/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.

Regardless of the errorcode returned in the response, we strongly recommend that you refer to our best practices and configure your system to perform all of the checks outlined.

Here is the specification of the fields that are included in the AUTH responses described above, which are specific to 3-D Secure:

Please note that other fields that can be returned are documented on our page covering AUTH requests.

xid	Alphanumeric	255		The unique identifier for the transaction, assigned by the MPI (Merchant Plug-In) (in this case, Trust Payments).
