Hi @Nem Lasica , have you defined an Azure Function linked service? Step #3 from:
Azure function fails when called via "Azure Function" but succeeds when called via "Web" in ADF

I have deployed an Azure function that runs successfully when tested from within the Azure Function App portal (Code + Test), Postman as well as the Web activity inside ADF, however, it consistently fails when called via the Azure Function activity with the below error:
**
Call to provided Azure function 'xxx' failed with status-'Unauthorized' while invoking 'POST' on 'https://xxx.azurewebsites.net' and message - 'Invoking Azure function failed with HttpStatusCode - Unauthorized.'.**
The function authorization level is set to "Function" and when calling the function via the Azure Function activity in ADF I provide the function (tried both, master and default) key via "x-functions-key" in the headers, yet it continues to fail.
Any ideas? Thanks!

2023-01-16T23:42:56.11+00:00 Hi @Silvia Wibowo I have. I have another function within the same Function App that works, although the authorization level is set to "Anonymous" for that function and not "Function".

2023-01-17T20:54:05.26+00:00 Hi @Nem Lasica , let me confirm my understanding of your situation. Please make correction as necessary.
One Function App, 2 functions:
- Function 1 - Authorization level = Anonymous.
- Function 2 - Authorization level = Function.
On ADF:
- Azure Function linked service for Function 1 defined: Function App URL, Function key for Function 1, Authentication method = Anonymous. Result: ADF can call Function 1 successfully.
- Azure Function linked service for Function 2 defined: Function App URL, Function key for Function 2, Authentication method = Anonymous. Result: ADF provides error 'Invoking Azure function failed with HttpStatusCode - Unauthorized.'
Did you define any identity (eg. Azure AD login) on your Function App? Note: "When you use anonymous authentication, ensure that you have taken down your identity on the Azure Function side."
