You imported an OpenAPI definition into APIM that includes example responses. The backend is not yet available, but frontend teams must be able to call GET /orders and receive a 200 response with the documented example payload without invoking any backend. What should you configure?

The mock-response policy is designed specifically for this scenario. It allows API Management to return example responses defined in the OpenAPI specification without forwarding the request to a backend. By applying it at the operation scope for GET /orders and specifying the 200 example, you enable frontend teams to test against a realistic response even when the backend is unavailable. The return-response policy is for constructing custom responses, not directly leveraging OpenAPI examples. Removing the backend and relying on rewrite-uri to serve a static JSON payload would require manually maintaining the JSON, which defeats the purpose of using the OpenAPI example. Configuring set-backend-service with a default backend URL would still involve an external service, which is not the goal when the backend is unavailable and you want to use an embedded example.
