Create a Custom OAuth Application

Creating a custom OAuth application for authenticating to Facebook involves obtaining the OAuth client credentials (App Id and App Secret), specifying a site URL for your application, and configure the OAuth redirect URI.

To obtain the OAuth client credentials:

1. Login to Facebook.
2. Navigate to https://developers.facebook.com/apps.
3. Create a new application.
4. Select Settings > Basic. The OAuthClientId (App Id) and the OAuthClientSecret (App Secret) display.
5. Navigate to the Settings tab.
6. To add a website platform, enter a Site URL.

To configure the OAuth redirect URI:

1. Go to your application settings and navigate to the Products section.
2. Add Facebook Login to the list of products.
3. Navigate to the product settings, and set the OAuth redirect URI:
   • For desktop applications, set the redirect URI to https://localhost:33333/, or a similar https url.
   • For web applications, set the redirect URI to a location that shoud be used as a callback URL, where the user returns with the token that verifies that application access has been granted.
