About Provider REST API Descriptors

You can create a provider REST API descriptor (RAD) from REST resources created using either the legacy approach (invoked using the rest directive) or the URL template-based approach (REST V2 resources invoked using the rad directive). You can also create a provider RAD containing REST V2 resources from a Swagger document.

Stage 1	Creating REST resources. During this stage, you create the REST resources that you want to expose in the RAD. For more information about creating REST resources, see Working with REST.
Stage 2	Create a RAD on Integration Server. During this stage, you create the RAD, specifying information such as supported MIME types, protocols, and host:port. Additionally, you add REST resources to the RAD. Integration Server uses this information in the Swagger document that it dynamically generates for the RAD.
Stage 3	Add security definitions and security for REST operations and RAD. During this stage, you can add the security definitions and then add security scheme for the REST operations.
Stage 4	Add tags and reference to an external documentation for the REST operations in the RAD. During this stage, you can add tags for the REST operations so that they can be logically grouped together. You can also add reference to an external documentation.
Stage 5	Modify information for the REST resources within the RAD. During this stage, you add or remove REST resources to the RAD.
Stage 6	Modify the operations for the REST resources in the RAD. During this stage, you can change the MIME types consumed or produced by a specific operation. You can also review the source values assigned to parameters and add or remove operation responses.
