REST models with single service APIs?

You can do this by adding Model Fields for both request and response information, to the same Model. For example, let’s say your Model has an Insert method that does a POST, and you need to send fields “Foo” and “Bar”. You would define two Model Fields, “Foo”, and “Bar”. Now, if the response from the POST is expected to return fields “Alpha” and “Beta”, you should add these as Model Fields as well. Then, in your Insert method config, make sure that “Created record will be returned in response body” is selected. After the POST response comes back, if it contains “Alpha”, “Beta”, “Foo”, and / or “Bar” properties, these will all be populated into the corresponding fields in the Model rows.
