Enable OAuth Three-Legged Authentication for Creating External Client Application

While creating an external client application using the Security Console, only the JWT custom claims authentication type is available in the Select Client Type list on the External Client Application Details page.

To display the OAuth three-legged authentication type for selection, you must enable it using a profile option.

Here are the steps:

1. In the Setup and Maintenance work area, go to the Manage Administrator Profile Values task.
2. Search for the ORA_ASE_ENABLE_OAUTH_THREE_LEGGED_SETUP profile option code
3. In the Profile Values section, click the Profile Values list for the Site profile level and select Yes.
4. Click Save and Close.

The OAuth three-legged authentication type is enabled now. Enabling the profile option displays the OAuth three-legged authentication type in the Select Client Type list on the External Client Application Details page.
