Dear RingCentral Support Team/Community Members,
For one of our application, we are using RingCentral Api to develop Send SMS feature. Weve followed steps as per RingCentral help documentation to generate OAuth token to send sms. We are NOT able to identify root cause why following api returns 400 error?
Can you please help us to sort out this issue? Please refer following snaps that weve tried to retrieve oAuth token.
Thanks in advance!
