In case you want to read about XML format here is a link to 1st part of this blog Sync Scenario using REST adapter in SAP PI – Part I

Scenario :

REST adapter can be used for consuming a REST service or exposing a REST service in PI. This blog will cover only exposing of REST service for which Sender REST Adapter will be used.

Flow:
