To register an app on Facebook:

1. Go to the My Apps page in Meta for developers.

2. Click Create App.

   

3. Select the use case as Authenticate and request data from users with Facebook Login and click Next.

   

4. Select the login type out of the options and click Next.

   

5. Provide Display Name and click Create App to create an application.

   

6. While in the created application, select Use cases from the left navigation.

7. Under Use cases > Authentication and account creation, click Customize.

8. Under Facebook Login > Quickstart, click Go to quickstart.

9. Select Web as the platform for this app and provide the following Site URL with your organization name and click Save.

   bash no-line-numbers https://api.asgardeo.io/t/<organization_name>

10. Return to the Use cases > Customize section and under Facebook login > Settings, click Go to settings.

13. On the left navigation panel, go to App settings > Basic and take note of the App ID and App Secret.

    

Register the Facebook IdP

Now, let's register the Facebook IdP in WSO2 Identity Server.

1. On the WSO2 Identity Server Console, go to Connections.
2. Click Create Connection and select Facebook.

3. Enter the following details of the Facebook identity provider and click Finish:

   

   Parameter	Description
   Name	A unique name for this Facebook identity provider.
   App ID	App ID obtained from Facebook.
   App Secret	The app secret obtained from Facebook.

When a user logs in with an external identity provider using the same email address registered in a local account, JIT-provisioning overrides the attributes of the local account with the attributes received from the external identity provider.

WSO2 Identity Server, by default, disables Just-In-Time (JIT) user provisioning for your external identity provider.

To enable JIT-provisioning,

1. On the WSO2 Identity Server Console, click Connections and select the relevant connection.

2. Go to the Just-in-Time Provisioning tab of the selected connection.

3. Check/Uncheck the Just-in-Time (JIT) User Provisioning checkbox to enable/disable it.

   

4. Click Update to save the changes.

Note

• Learn more about JIT provisioning configurations in configure JIT user provisioning.

• You can use the identity provider APIs to customize the attribute syncing behavior between the external identity provider and WSO2 Identity Server.

After the Facebook identity provider is created, go to the Settings tab and see the list of permissions granted by Facebook to WSO2 Identity Server.

• email: Grants read access to a user's primary email address.
• public_profile: Grants read access to a user's default public profile details.

Note

WSO2 Identity Server needs these permissions to get user information. WSO2 Identity Server checks the attribute configurations of the application and sends the relevant attributes received from Facebook to the app. You can read the Facebook documentation to learn more.
