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.
