Return response
APPLIES TO: All API Management tiers
The return-response
policy cancels pipeline execution and returns either a default or custom response to the caller. Default response is 200 OK
with no body. Custom response can be specified via a context variable or policy statements. When both are provided, the response contained within the context variable is modified by the policy statements before being returned to the caller.
Note
Set a policy's elements and child elements in the order provided in the policy statement. Learn more about how to set or edit API Management policies.

Usage
- Policy sections: inbound, outbound, backend, on-error
- Policy scopes: global, workspace, product, API, operation
- Gateways: classic, consumption, self-hosted
Usage notes
- A liquid template doesn't work when specified inside the body (set using
set-body
) of thereturn-response
policy. Thereturn-response
policy cancels the current execution pipeline and removes the request body and response body in the current context. As a result, a liquid template specified inside the policy receives an empty string as its input and won't produce the expected output.
Example
<return-response>
<set-status code="401" reason="Unauthorized"/>
<set-header name="WWW-Authenticate" exists-action="override">
<value>Bearer error="invalid_token"</value>
</set-header>
</return-response>
