Facebook Identity Service

With a Facebook identity service, a user can access Facebook resources through Volt MX Foundry applications. Volt MX Foundry supports OAuth2.0 authentication mode for Facebook identity service.

For example, when a user logs into a Volt MX Foundry application by using the Facebook identity provider, the Volt MX Foundry application redirects the user to log in to a Facebook account. After the user logs into Facebook, Facebook issues an authorization code to the user. The user sends the authorization code to the application. Volt MX exchanges the authorization code for the access token and issues Volt MX token. By using Volt MX token, the user can access the application or web resources.

How to Configure a Volt MX Facebook Identity Service

To configure a Facebook identity service using OAuth 2.0 authentication mode, follow these steps:

  1. Under the Identity service designer page, type a name for the service in the Enter Service Name text box.

  2. From the Type of Identity list, select Facebook.

    Note: Fields marked with an asterisk are mandatory.

  3. In the Client Id text box, enter the app key of the app instance that you created on Facebook.

  4. To move the cursor to the next text box, press the Tab key or click in the text box. In the Client Secret text box, enter the app secret key of the app instance that you created on Facebook.

    • In the Login URL text box, the default URL (https://graph.facebook.com) is displayed. You cannot modify these details.

    • In the Callback URL text box, the default URL is displayed. You cannot modify these details.

  5. In the Scope text box, enter the list of permissions that a user needs to provide while in the user Facebook log-in page. The list can contain more than one permission. The list must contain a comma-separated valid permission. The list of permissions accepted by Facebook does not contain spaces. For the full list of permissions, refer to Permissions with Facebook Login.
