Answer 1

I ran into this with a generic web hook function. The workaround I found was:

1. Go to the Function app page in the Azure portal
2. Select your app - You should see the menu with options "Develop", "Integrate", "Manage" and "Monitor"
3. Select "Manage"
4. There are two groups of keys - Function keys and Admin keys. The default Admin key was being used, so I changed the "code" parameter in my query to use the default Function key.

If that still doesn't work, you might want to try renewing the keys or adding a new one.

Answer 2

Goto yourfunction->manage->functionkey->default -click on the copy link under actions

Just appending code

https://{functionappName}.azurewebsites.net/api/{functionName}?code={defaultfunctionkey}

Answer 3

Hi this workaround worked for me

• in your logic app replace the AzureFunctionCall activity with the HTTP activity
• method POST
• url: https://FUNCTION_CONTAINER.azurewebsites.net/api/FUNCTION_NAME?code=DEFAULT_FUNCTION_KEY
• same body
• content-type application/json

Hope it helps
