After creating a REST service using the Define Service Interface wizard, you must map REST operations to ABL operations.

To map REST operations to ABL operations:
  1. Add REST resources to the defined REST service.
  2. For each resource, map REST (HTTP) verbs to operations (methods, procedures, and functions) of the annotated ABL class (.cls) and/or procedure (.p) file.
  3. For each REST verb, map the HTTP Request and Response parameters to the Interface parameters.
