Working with Operations
In a REST API descriptor, each included REST resource lists the associated operations. For each operation, Designer displays the parameters used by the operation and the responses returned by the operation. Designer also displays a description of the operation which Designer obtains from Comments tab for the corresponding resource operation. For each operation in a REST API descriptor, you can do the following:
Change the MIME types that the operation consumes or produces
Review the assigned source of the parameter and change the source if necessary.
Add and remove responses.
