How to View Effective Policy of an API Operation 2017 version? My API operation is not calling the backend service.

If your API operation is not calling the backend service, you need to view the effective policy of the API operation to see why backend service is not called.

1. Go to the publisher portal of the API Management Service.

2. Click "Policies" on the left menu. You see the gateway policy definition page.

3. Select "First API" in the API dropdown list.

4. Select "Add new user" in the operation dropdown list. You see the system generated gateway policy displayed.

5. Click the "View effective policy for selected scope" button. You see the effective policy displayed:

<policies>
	<inbound>
		<rewrite-uri template="/profiles" />
	</inbound>
	<backend />
	<outbound />
	<on-error />
</policies>

The empty "backend" section is telling the API gateway to not forward the request to the backend service. This is why there is no backend actions in the test trace report.

To fix the issue, you need add the "forward-request" policy statement in the backend section as demonstrated in the next tutorial.
