AUTH

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.

Merchants that process e-commerce transactions MUST support 3DS authentication. Click here to learn more.

The following content should only be utilised by merchants processing Mail Order Telephone Order (MOTO) payments or other workflows that are exempt from the PSD2 mandate.

When testing the AUTH request, ensure you submit your test sitereference. This ensures that transactions are processed to our test bank and no money will change hands. When you go live, you will need to swap out your test site reference for your live site reference.

Click here for test card numbers you can submit in AUTH requests while testing.
