You must create a custom OAuth app to connect to Bullhorn CRM.

The only way to create an app is to contact the Bullhorn CRM support team. They will provide you with the application credentials (clientId and client secret). You can find more information about how to register here.

In addition, the CallbackURL or Redirect URI defaults to a page on bullhorn.com.

In order to set InitiateOAuth to GETANDREFRESH, you must contact Bullhorn CRM staff and request a separate CallbackURL.

If a separate Callback URL cannot be specified, the "code" parameter from the redirect page on Bullhorn CRM must be taken and passed as an input to either:

• The Verifier input of GetOAuthAccessToken if executing it manually.
• The connection property OAuthVerifier when setting InitiateOAuth to GETANDREFRESH.
