Microsoft Graph API Webhook Subscription Request gives Invalid Token Error for a Valid Token

Jamaluddin Khan 0

Hi,

When I generate the access token and request change notification subscription for /teams/getAllMessages without resource data, I am getting the following error:

User's image

However, the access token being used here was generated just 2 mins before the above call. The lifespan of the access token is 60 minutes here so this should not be the case.
Also, the required permission to receive notification would be ChannelMessage.Read.All which has been already granted to the application.

PFB the granted consents to the application:

User's image

It is a humble request if anyone has any idea why this unexpected response to the token is being received, please let me know. Your help will mean a lot!

Thank you

Hello Jamaluddin Khan,

Thanks for reaching out!

We would need some more details about this app that you are using particularly would like to know the request URL that is being sent by this app to AAD while trying to fetch the token from AAD. Do share us the following details so that we can dig in a little deeper to figure out the point of failure.

Request URL from App to AAD, while requesting for the token

The type of OAuth flow being used here

The URL and request body being used for making the Graph API calls

Please decode the access token using jwt.ms and check the permissions.

Do share us the following information so that we can understand the failure better and help you further.
