    Hello Sony !

    Thank you for posting on Microsoft Learn.

    Go to the Function App > Monitoring > Logs (Application Insights) and check if any requests are coming in at all.

    If yes, do you see errors or 400/500 response codes ? if no requests are coming in, maybe the issue is external.

    If your function requires an API key (function or host key), has the key expired or been rotated?

    You can check the expected x-functions-key is still valid and properly sent by the webhook.

    Try to use curl or Postman to simulate a call:

    curl -X POST https://<your-function-url> -H "x-functions-key: <your-key>" -d '{}'

    If it succeeds manually but fails from the external system, the issue then lies with the webhook provider.
