SAML SSO vs OAuth Client Credentials for ServiceNow Integration

Quick question about auth setup.

  • Enabled SAML SSO for users, but ServiceNow needs headless API access.
  • Using /api/v2/oauth/token with client_credentials grant.
  • Getting 401 Unauthorized despite valid client_id/secret.
  • Does SAML enforcement disable OAuth client credentials?
  • Need to know if I must disable SAML or use a specific scope.
