When an Instant Payment is created in the Origix IP system it is given a unique identifier (the URI). This identifier is returned in the response to the Create Instant Payment request.
The Retrieve Instant Payment request allows you to look up the details of a given payment. The payment’s ID, end-to-end identifier, time stamp etc. are all returned.
You must provide the transaction’s unique URI as a GET request:
When working with our APIs, please use the Sandbox URI when testing and the Live URI when you move to Production.

If you haven't done so already and would like to do some testing, please Request Sandbox Access
Important: Endpoints may be extended from time to time and any changes we make will follow our Versioning and Backward Compatibility rules. This means that the code that you write today must be designed to be robust enough to handle any future changes (where a new object is added to (or removed from) a specific API response, for example).
