We are making an interface with SharePoint. I did the app registration in AAD, gave SPO degelated permissions via Graph API
API call for access token works fine API call to get a file keeps erroring with a 403 forbidden.
Error message: 917656; Access+denied.+Before+opening+files+in+this+location%2c+you+must+first+browse+to+the+web+site+and+select+the+option+to+login+automatically.
Google doesn't help me any further... Maybe you guys can help me out?
