 ## Reference backend using set-backend-service policy
 
-After creating a backend, you can reference the backend in your APIs. Use the [`set-backend-service`](set-backend-service-policy.md) policy to direct an incoming API request to the custom backend. If you already configured a backend web service for an API, you can use the `set-backend-service` policy to redirect the request to a custom backend instead of the default backend web service configured for that API.

 # Set backend service
 Use the `set-backend-service` policy to redirect an incoming request to a different backend than the one specified in the API settings for that operation. This policy changes the backend service base URL of the incoming request to a URL or [backend](backends.md) specified in the policy.
