SAP Cloud Platform Integration (SAP CPI) is a versatile middleware solution that enables seamless integration between diverse applications and systems, both on-premise and cloud-based. One of the key components in SAP CPI’s integration scenarios is the REST Adapter, which facilitates communication using RESTful web services—a popular standard for modern APIs.
This article provides a comprehensive overview of configuring REST adapters in SAP CPI, focusing on their purpose, key configuration settings, and best practices for integrating RESTful services.
The REST adapter in SAP CPI is designed to enable inbound and outbound communication using REST (Representational State Transfer) protocols. RESTful services typically exchange data in JSON or XML format over HTTP/HTTPS, supporting operations such as GET, POST, PUT, DELETE, and PATCH.
In SAP CPI, REST adapters are used in two main contexts:
Start by opening your integration project in SAP CPI’s Web UI or SAP Web IDE. Create a new integration flow or edit an existing one where you want to use the REST adapter.
Drag and drop the Sender or Receiver REST adapter onto your integration flow.
General Settings:
/orders or /customers/{id}.Message Format:
Authentication:
Additional Options:

Often, the sender and receiver systems use different data formats. Use message mapping or content modifiers in your iFlow to convert JSON to XML or vice versa, or to enrich the data payload before sending or after receiving the message.
Once configured, deploy your integration flow and test the REST endpoints using tools like Postman or curl to ensure the REST adapter works as expected.
Configuring REST adapters in SAP CPI is essential for integrating modern RESTful web services, enabling enterprises to build agile, scalable, and secure integration scenarios. By understanding the key settings and following best practices, integration developers can harness the full power of SAP CPI to connect cloud and on-premise applications seamlessly.
