Configuring Sign-In with Facebook

To configure sign-in using Facebook on your WHMCS installation:

1. Create a Facebook App.

To use sign-in integrations with Facebook, you must create a Facebook app. You can do this using your existing Facebook account. Users will only see the app name that you define. They will not see anything relating to the account that you use to create the app.

You can’t change the Facebook account under which you create the app without requiring users to reauthenticate and re-link their accounts.

To create your app in Facebook:

  1. Visit the Facebook developer portal.
  2. Log in to your Facebook account.
  3. Click Create App.
  4. Select Other for Add Use Case.
  5. Select Consumer as the app type.
  6. Click Continue.
  7. Enter a display name for App Name. This is the name that users see when authorizing your app. We recommend using your company name.
  8. Enter your email address for App Contact Email. The system uses this email address for important communication about your app.
  9. Click Create App.
  10. Under Facebook Login, click Set Up.
  11. Select Web as your platform.
  12. Enter the full URL to the root domain of your website.
  13. Click Save.
  14. Click Continue.

2. Configure the App Permissions.

To configure the required permissions for your Facebook App:

  1. From the App Review menu, select Permissions and Features.
  2. Locate the public_profile option and click Get Advanced Access.
  3. Agree to the request and click Confirm.

3. Retrieve the App Credentials.

To retrieve the Facebook App credentials from your Facebook account:

  1. Go to the Facebook developer portal.
  2. From Settings, select Basic.
  3. Click Show to view the App ID and Secret.
    Viewing Facebook app credentials

4. Configure the App in WHMCS.

To enable sign-in integrations with the Facebook app in your WHMCS installation:

  1. Log in to the WHMCS Admin Area.
  2. Go to Configuration () > System Settings > Sign-In Integrations.
  3. Select Activate under Facebook.
  4. Enter your credentials for Facebook App ID and Facebook App Secret.
  5. Click Save & Activate.

WHMCS will attempt to validate and test the details that you have entered. If the credentials are valid and successfully authenticate with the Facebook API, the system will save them.
