I have been using the Microsoft Graph to do a lot of SharePoint stuff, but am finally stumped. I need to add a list item with both managed metadata and multiple choice columns. This does not seem to be available via the Graph API.
I also am unable to query the SharePoint Rest API via the Graph tokens I have.
So my question is twofold:
1) Any insight on adding that item via Graph API?
2) What is the best way to get an access token for SharePoint Online's rest api?
