The Paymentsite Universal API is a server-side application (Web service) that provides access to transaction processing services.
All communications take place over secure HTTPS links on the Internet.
Requests are sent to the payment processing servers by "POSTing" XML or JSON data that has been formatted per the schema defined in this specification.
The response is returned as XML or JSON data in the body of the HTTP reply.
Before you can begin testing, you will need a test account with Paymentsite. Please contact us at
firstname.lastname@example.org to set up your test account.
Test accounts are not connected to the payment processor and even though you will receive a response from each request sent,
transactions sent to a test account are not actually processed and no money is moved.
Your test account information should include a merchant ID and a key that you will include in all requests you send to the Paymentsite system.
This merchant ID and key is merchant specific.
The posting URL to use for testing API transaction requests is as follows. This URL is strictly for posting transactions such as auth, capture, sale, return, etc.
Posting URL for test transaction requests: https://apiint.paymentsite.com/UniversalAPI/postXML
When passing transactions through a test account a simulated payment gateway will be used. All valid transactions will approve unless the transaction includes values that are intended to trigger specific responses. For more information on triggering specific responses, please see the Simulator Response Behavior guide.
The posting URL to use for testing other API requests (requests such as add-consumer, which are not transactional in nature) is:
Posting URL for test requests which are NON-transactional: https://apiint.paymentsite.com/UniversalAPI/postAPI
