I am trying to setup an API Poller to Microsoft 365 services using OAuth2. I believe I have everything setup correctly but I am not receiving any data back. Has anyone else had any success with configuring these pollers?
Are there any errors messages coming back on the api page? That will give some clues. Otherwise, postman will help a lot to test and troubleshoot. postman is a third party api dev and testing tool and its free. I recall that the https://manage.office.com/ was deprecated - although I still find references to it on Microsoft. UGH. There is a new MS 365 template on thwack : Microsoft 365 Admin Center - API Pollers - Server & Application Monitor - THWACK (solarwinds.com) This is pointed at graph.microsoft.com and uses oath2. There are two constants with Microsoft API's, one they are frequently changing, and two, they are frequently updating them. Hopefully someone else on thwack who has had more experience with Microsoft APIs can pipe in.
Also did you make sure to change the auth setting in the API poller itself? It can be a bit hidden if you didn't look around when defining/creating the API poller.
