You would like to send custom HTTP Header to the target API, e.g., the custom HTTP headers like "Authorization" that created in Basic Authentication policy.
However even if the headers' values are generated successfully, but the runtime API Proxy is not sending the correct HTTP header.
You can check the HTTP trace from target API server to verify it.
A typical example is that, you might observe the API Proxy is forwarding the HTTP header like "Authorization" that defined by client when calling API Proxy, instead of using the "Authorization" that created in Basic Authentication policy.
As the consequence, the target API will response HTTP 401 or 403 code.
