IBM® Integration Bus provides an AppConnectRESTRequest node, which enables interaction with an IBM App Connect REST API.
You can use an AppConnectRESTRequest node in a message flow to issue requests to an IBM App Connect REST API. The AppConnectRESTRequest node uses an imported Swagger document (in either JSON or YAML format), which defines the REST API and the operations that are available. When you have downloaded the Swagger document, you can import it from your toolkit workspace and select the operations that you want to invoke. For more information, see AppConnectRESTRequest node.
Alternatively, you can configure a connection to an App Connect API by using an App Connect REST Request pattern, which is available through the Patterns Explorer. For more information about using patterns, see Developing integration solutions by using patterns.
