Additional Server features & protocol guidelines (optional)

Single-click purchases (optional)

Give shoppers the option to store their card details (as a token) on our payment system so that they don't have to re-enter them during their next purchase. Ideal for businesses that have a lot of repeat customers. See pricing

Customise your checkout pages (optional)

These templates are useful if you wish to customise the look and feel of your checkout pages.

V3 Custom checkout templates

Important - these pages are not the Opayo mobile optimised payment pages. These files relate to the standard Opayo customised checkout pages.

Download our official logos and graphics

Download the Opayo logo and payment type graphics for your checkout pages. Including logos at the bottom of checkout pages will give your website more credibility.

Customised reporting & admin API (optional)

This API allows your back-office systems to interact with our payment gateway instead of using our own reporting & admin portal called MySagePay.

Step 2 – Test your integration

Upon completion of the integration, you will need to test it by attempting to process a transaction and refund through our test server. An online guide is available to walk you through each step of the process.

Step 3 – You're all set

Once you've processed a successful test transaction and refund, a trigger will be generated automatically to notify us that the account should now be switched from test to LIVE. Shortly after, the vendor will receive an email confirming that the account has been switched.

If the merchant account(s) on the account were already verified by Opayo, the vendor will be able to process LIVE transactions immediately.

Otherwise, feel free to get in touch with our 24/7 customer support team to check the status of an account.
