REST Adapter scenario in SAP PI - JSON/XML

This blog will provide a step-by-step guide on how to configure the sender REST adapter scenario in SAP PI. This document will help the PI developer/consultant who will like to learn about the Sender REST adapter configuration.

Async Service interface Inbound/Outbound
Message Mapping
Operation Mapping

Mapping

Convert to XML need to be enabled.

Channel Selection is an EndPoint configuration any name can be given here.

In this case, the endpoint will look like

http://:/RESTAdapter/test/

REST Resource tab

REST Operation tab

Download using below link
