Smart Transaction Systems XML-based API

Doing your own thing or prefer not to use a library? Integrate with us using our XML API.

Our SSL Transaction Gateway gives you the ability to process real-time gift or loyalty card transactions via the Internet. The STP SSL gateway can be used for gift and loyalty transactions originating from a variety of channels within your organization including:

  • e Commerce shopping cart
  • Mail/Phone order call centers using IP capable software
  • POS systems at retail stores

Our SSL Transaction Gateway utilizes the http post protocol to simply the process of transmitting and receiving transactions. It is a simple request-response protocol that is supported in all modern development environments. Additional details on the protocol can be found at http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

You initiate a transaction by creating an authorization request string and sending it to the us. We reply with an approve/decline/error response which comes back to you in an XML string that it is embedded in the response to your http post.
