Web Services

Secure Trading Web Services is for merchants who want to use their own secure servers, but wish to use Secure Trading’s payment network as part of their own ecommerce application. The Web Services interface allows merchants to submit a request to Secure Trading using a client program, providing a username and password for authentication. Unlike STAPI, no client needs to be installed on your own server to use Web Services.

Using Secure Trading Web Services you can:

  • Automate refunds and authorisation reversals, and control the settlement schedule for each transaction.
  • Have development capability and write applications that can process payments.
  • Integrate a payment solution into back-office or legacy systems.
