Office 365 Groups are great, both from a user perspective, and they are also fun to work with as a developer. This time around I wanted to list all Office 365 Groups which have been created via Yammer, as a means to differentiate the type of Office 365 Groups for users.
I started to dig around on properties on the Group object at the /beta endpoint and found the following for a Yammer originating Office 365 Group.
"resourceBehaviorOptions": [ "YammerProvisioning" ]
Turns out you can use above information in a filter on the /beta/groups endpoint. Using a GET query where you filter on both Unified groups and the YammerProvisioning attribute, will yield the list you are looking for. You can probably omit the groupTypes filter, but it sure doesn’t hurt.
https://graph.microsoft.com/beta/groups?$filter=groupTypes/any(g:g eq 'Unified') and resourceBehaviorOptions/any(r:r+eq+'YammerProvisioning')
There is still no API on the Microsoft Graph to create Yammer enabled Office 365 Groups, but at least we’re one step closer.
Permission wise you need Group.Read.All as either delegated or app only to query for Groups, which means you can easily do this using the GraphHttpClient for SharePoint Framework.
