401 Unauthorized while accessing azure function with bearer token | function app is secured with AAD

Question

I have a simple function app with HTTP trigger: Function app code snippet

I have authorized my function app with AAD. I am able to get the access token successfully from v2 token url https://login.microsoftonline.com/<TENENT_ID>/oauth2/v2.0/token

In scope I am passing the Application ID URI from app registration.

Access token

But when I am trying to pass the access token in header while invoking function app url, I am getting 401. 401 postman

Not sure what I am missing. Please help

@StanleyGong, nope, it is still there. I already tried your solution previously, but no luck. What exactly I need to pass in scope? — aneesha chaudhury, Jun 15 '21 at 15:30

I think my previous post would be helpful. Let me know if you have any more questions.

If this solution does not work for you,and scope param is necessary for you, I have checked your post, seems everything is right. I assume it is due to Auth config ,could you pls have a check?Go to Azure function => Auth => identity provider => find your app => Edit.

I'll share my config and steps to call function below:

My config:

The way I get the access token :

Not bring token:

Use this token to call Azure function :
