REST Adapter in SAP PI

The REST adapter in SAP PI enables you to exchange messages with partners via the REST Services APIs.

REST stands for Representational State Transfer which is architecture style on how to exchange light weight messages over the http protocol.

Most commonly used data type in REST adapter is JSON.

You can even exchange JSON, XML or any other custom data format.

REST is built on HTTP protocol which means you can transfer anything over HTTP adapter with the different HTTP operation:

  • GET – Fetch information from the API.
  • POST – Send message in the body to the API. Most used for CREATE Records.
  • PUT – This is used to UPDATE the Records.
  • DELETE – This is used to perform DELETE operation.

When you exchange JSON based data type in REST receiver channel or rest sender channel there is built in support to convert to xml from json and vice versa.
