Microsoft-Graph use $filter on webhook subscriptions
I'm interested to use webhook to notify me when a user was added/removed from a Team on Microsoft Teams. But do not create a subscription for each team I prefer to enter in the filter the team that I am interested in being notified. So I used this Request: POST https://graph.microsoft.com/v1.0/subscriptions { "resource": "groups?$filter=mail eq 'someGroupmail@domain.com' or 'ohterGroupMail@domain.com'", "changeType": "updated", "clientState": "1234", "notificationUrl": " https://1234.ngrok.io/xxxxx ", "expirationDateTime": "2019-01-05T12:21:25Z" } The subscription was successful created
