Configuring Integration Objects for REST API Data Access
An additional Business Object can be exposed through the Siebel REST API by creating an Integration Object for the Business Object, Base <Business Object Name>. Each Integration Component in the Integration Object should have an Integration Component Key, REST ROWID User Key:1, with one Integration Component Key Field Id defined. Without the Integration Component Key, the REST API upsert requests will not work on the Integration Component. For example:
If BO = "Service Request" then the IO name must be "Base Service Request"
