Define the sign-out callback

After you sign users out of your app and out of Okta, you have to redirect users to a specific location in your application. You need to whitelist the post sign-out URL in your Okta application settings.

Open your Okta Developer Console:

Go to Console

1. Select Applications, and then select your application.

2. Select General and click Edit.

3. In the Logout redirect URIs section, add the base URI of your application.

4. Click Save.
