Do I just re-upload the merchant files?

No, there are no files to upload, other than any CSS/Javascript files you might use to modify the look of your payment pages.

I use multiple payment pages on ST2K. Can you still do this on STPP?

Yes, you can create multiple CSS and/or Javascript files to change the styling of each of your payment pages. If you are also using multiple callbacks on the legacy system, we will set you up with multiple site references on the new system so you can configure notifications and redirects appropriately.

I use callback on the legacy platform, can I still use it on the new STPP platform?

The callback function has been replaced with notifications and redirects.

Can I still customise the appearance of my payment page?

Yes, you can fully customise your payment page using CSS and Javascript.

What new features are there in STPP?

By migrating to STPP you can take advantage of a wide range of new features:

  • Card Store: allows you to store a customer’s card details in our system without performing an initial authorisation payment. These details can then be used for future authorisations.
  • Tokenisation: allows you to use the unique ID of a previous transaction as a token for future transactions from the same payment instrument that was used.
  • Account check: helps you to minimise fraud – validate payment and customer details without funds being reserved or transferred by the request.
  • Multiple Usernames: MyST can by used by multiple users with different access levels.
  • Enhanced Reporting: a more sophisticated and flexible version of MyST means you can build any report that you might need and gain far more detailed business intelligence.
  • Webservices: if you are using our ST2K API, you can move across to our Webservices on the new platform, which will allow you to directly send and receive payment requests without having to install and support a Java Client on your server.

I run repeat transactions in ST2K. Can I still repeat them in STPP?

The repeat option is still available within the new platform, but your legacy system initial transactions are separate and cannot be carried over to the new platform – meaning you will have to start the transactions over. Please email [email protected] for further information.

Are refunds, authorisations, settlements and fraud/risk checks supported on the new platform?

Yes, all the features of the old platform are also available on the new platform – along with lots of new capabilities.

Can I use ST2K and STPP at the same time while I am integrating?

Yes, they are completely separate systems and do not affect each other.

Is my shopping cart compatible with the new platform?

Please refer to for a list of shopping carts that are already integrated to the new platform. If you can’t see your shopping cart there please let us know and we can advise you of the migration plan.
