IBM® Integration Bus provides a RESTRequest node, which enables you to interact with external REST APIs.
You can use a RESTRequest node in a message flow to issue synchronous requests to external REST APIs. The RESTRequest node uses an imported Swagger document in either JSON or YAML format, which you can import from the toolkit workspace, your file system, or from a URL.
If you have created a REST API from scratch in the IBM Integration Toolkit, a Swagger document was created for you, which you can now import and use with the RESTRequest node.
