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).
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) are mandated to use 3-D Secure when processing e-commerce transactions, as part of the PSD2 mandate.
To process an e-commerce transaction that is authenticated with 3-D Secure, you will need to utilise our JavaScript Library instead of the solution described below. Click here to get started.
The following content should only be utilised by merchants processing Mail or Telephone Order (MOTO) payments, Merchant Initiated Transactions (MIT), or other workflows that are exempt from the PSD2 mandate.

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.

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.
- For those using Payment Pages, if you’re unsure where to start with your testing, you may find this resource helpful.
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.
For Mobile SDK implementations:
After your Android or iOS app has been updated to utilise our Mobile SDK, process a payment using one of the card numbers listed above and your app 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:


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.

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:

Testing DCC
Please refer to the following resources when testing DCC:

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:
#!/usr/bin/python
import securetrading
stconfig = securetrading.Config()
stconfig.username = "[email protected]"
stconfig.password = "Password1^"
st = securetrading.Api(stconfig)

}
strequest = securetrading.Request()
strequest.update(threedquery)
stresponse = st.process(strequest) #stresponse contains the transaction response
<?php

$api = \Securetrading\api($configData);
$response = $api->process($requestData);
var_dump($response->toArray());
?>

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 example below demonstrates the structure of a THREEDQUERY response, indicating that the customer’s card is enrolled in a 3-D Secure scheme:

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



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 :
<!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=="
}]}'

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:
#!/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. |
