Understanding Guaranteed XAPI Events

XAPI is a JD Edwards EnterpriseOne service that captures transactions as the transaction occurs and then calls third-party software, end users, and other JD Edwards systems to obtain a return response. A XAPI event is very similar to a real-time event and uses the same infrastructure to send an event. The difference between a real-time event and a XAPI event is that the subscriber to a XAPI event returns a reply to the originator. The XAPI event contains a set of structured data that includes a unique XAPI event name and a business function to be invoked upon return. Like real-time events, XAPI events can be generated on a JD Edwards EnterpriseOne server using a JD Edwards EnterpriseOne HTML client. XAPI events also can be generated by a third-party system and sent to a JD Edwards EnterpriseOne system for a response.

The XAPI structure sends outbound events and receives replies. An event is first generated by the XAPI originator and then sent to a separate system, the XAPI executor, for processing. The XAPI executor then sends a response back to the XAPI originator. The XAPI structure provides for these three possibilities of originator and executor combinations:

  • JD Edwards EnterpriseOne to third-party.

  • Third-party to JD Edwards EnterpriseOne.

  • JD Edwards EnterpriseOne to JD Edwards EnterpriseOne.

When you use JD Edwards EnterpriseOne-to-EnterpriseOne events processing, you must map business functions and APIs.
