Are you receiving the following error when you call the /oauth/token API to authorize your application?
{ "error": "unauthorized_client" "error_description": "Unauthorized for this grant type" }
To fix this problem, check the following:
Is your "application type" ==> "Web/UI based" or "browser-based application?"
If the answer is yes you will need to follow the 3 legged OAuth flow to authorize your application.
The authorization code flow provides the following benefits:
- a consistent and trusted UI
- integrated password reset
- integrated single sign-on (SSO) via SAML support
