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 the 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, v2, consumption, self-hosted, workspace
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>
