Description of the illustration read_only_fields.png

This illustration shows two views of the Edit Method page: one shows the payload shaped for the response body, the other shows the payload shaped for the request body. In this illustration, the two payloads aren’t aligned; for the response, all of the fields are in the Selected window. The Selected window for the request, however, contains a subset of these fields, which allows them to accept user input. The field that’s in the Available window for the request, but in the Selected window of the response, will be read-only.
