[SOLVED] Create subscription to a group conversation using microsoft graph api

Create subscription to a group conversation using microsoft graph api

I would like to create a subscription to a user's group conversation. In order to do so, I have an api call to https://graph.microsoft.com/v1.0/subscriptions with the following payload -

{
    "changeType": "created, updated",
    "clientState": "something",
    "expirationDateTime": "2022-11-04T13:29:33.988006Z",
    "notificationUrl": "https://some.com",
    "resource": "groups('{id}')/conversations"
}

But I am getting this error code (400 status code) - Subscription to a group's 'conversations' is not supported with Application-level permissions.

According to the docs here - https://learn.microsoft.com/en-us/graph/api/resources/conversation?view=graph-rest-1.0 I should be able to do so, however, I get that error (using indeed, application permissions, and I cannot use user delegated permissions for my purposes)...

Solution

According to the documentation, it's not possible to create a subscription for conversation resource with application permissions.

No workaround right now if you cannot use user delegated permissions.
