I am attempting to request an access token via Microsoft’s Graph API with the Web Request node in Automator and it’s failing saying that I am missing the “grant_type” parameter. I have already verified the (near) exact config works from a PowerShell Invoke-WebRequest command. Does anyone have any ideas? I’ve attached my config and the “Test Web Request” output/response.
