Trouble Integrating Azure API Management with Azure Functions using C# and Authentication Issues
I'm working with issues when trying to integrate Azure API Management (APIM) with my Azure Functions, specifically with authentication headers... My Azure Function is set up to require an API key, and I've created a product in APIM that exposes the function. However, when I send requests from APIM, I receive a 401 Unauthorized behavior. In the APIM configuration, I added a subscription key to the header using the following policy: ```xml <set-header name="Ocp-Apim-Subscription-Key" exists-action="override"> <value>{{subscription-key}}</value> </set-header> ``` Yet, I still see the behavior. I also ensured that my Azure Function has the appropriate CORS settings to allow requests from the APIM endpoint. To troubleshoot, I used Postman to directly call the Azure Function with the same subscription key and it worked perfectly. I double-checked the APIM settings and even tried re-generating the subscription key, but still no luck. Additionally, I verified the Azure Function's authentication level is set to 'Function'. Is there something I'm missing in the APIM configuration, or is there a specific way to debug this scenario? Any guidance on what other settings might affect the interaction between APIM and Azure Functions would be greatly appreciated. I'm working in a macOS environment.
