  • Select the actions, and any events, to enable for this Connector Profile.
  • Click Continue.
  • Select Authentication Type as OAuth 2.0.
  • Fill out the fields using details retrieved from your provider:

 Congratulations! The new Connector Profile now shows up on the connector page. If you created it as a project member rather than an admin, it starts disabled until a project admin enables it.
