Create REST Integration using Oracle Integration Cloud

Using OIC this post explains easiest way to create a REST API using OIC integration

Step 1: Create an outbound Rest Connection using adapter as REST and type as INVOKE. Keep Connection Type-REST API Base URL

Provide- REST URL and Security Policy as needed to create Outbound

Step 2: Create Generic Inbound Rest Connection using adapter as REST and type as TRIGGER. The creds needed to invoke will be basic and will be same as the creds needed to login to OIC.

Step 3: Create a Basic Routing integration (Basic App to App with Data Routing). Drag the REST connection created in Step 2 

Provide a Name and DataType in Specify Query Parameters.

Configure the Response Payload

Click enter sample JSON which corresponds to the Invoke Connection created in Step 1

{

  "id": "Value"

}

Step 4: Drag the REST connection created in Step 1 into Drag and Drop an Invoke and perform the same steps as done in Step 3

Step 5: Do the mapping for Execute and Execute Response. Do validations and the mappings should now look green. 

Step 6: Add tracking. 

Step 7: Activate the integration

Step 8: Get the URL details and set up the SOAP UI with the URL. Give the UserId and Password used to login the OIC. Provide the Domain from the URL.

Step 9: Add the string, since it’s a GET and provide value. Run the request and the response received will be response.
