If you are using Facebook Login for the first time

• Due to changes in Facebook’s policy, new integration with sites using HTTP is not allowed.
• To enable HTTPS access, you need to apply SSL (Secure Socket Layer) on your store.
• Cafe24 stores don't automatically redirect HTTP to HTTPS; a separate JavaScript modification is required for HTTPS redirection.
  Since the URL changes, it may be considered a separate site. If existing links on portal sites or banners use the HTTP address, applying HTTPS redirection may affect them.
  (New stores may also encounter issues when running ads in the future.)

If you are using Facebook Login with only an App ID

You do not need to create a new app. Simply retrieve the App Secret from the existing app and enter it.
If you issue a new app, existing users who registered with Facebook may not be able to log in.

How to register as a Facebook developer

1. Go to the Facebook Developers site and log in with your Facebook account or create a new one.
2. After logging in, create a new app by clicking My Apps Create App and selecting Consumer as the app type.

How to integrate Facebook Login

1. Go to SettingsBasic of the created app and fill out the required information.
   • App Domains: Enter your store's domain where you want to use Facebook Login. If you plan to use it on mobile, include your mobile store domain as well.
   • Privacy Policy URL: Enter the URL of the page where your store’s privacy policy is published.
   • Terms of Service URL: Enter the URL of the page with your store’s terms of service.
   • User Data Deletion: Choose Data Deletion Instructions URL and enter the URL of the page explaining how to delete a social login account.
   • Category: Select Shopping.
   • App Icon: This icon is displayed to customers when they log in to your store using Facebook Login.
     Upload a JPG, GIF, or PNG file with a size between 512x512 and 1024x1024 pixels, under 5MB.
2. From the left menu, go to the Add Product screen and click the Set Up button for Facebook Login.
3. If a screen appears with instructions to implement app login using Quick Start, along with Android and iOS images, do not proceed with the setup. Instead, go to the Facebook LoginSettings screen on the left.
4. In Client OAuth Settings, enter the following in the Valid OAuth Redirect URIs field and save. (HTTP addresses cannot be entered):
   • https://{domain}/Api/Member/Oauth2ClientCallback/facebook/
   • https://www.{domain}/Api/Member/Oauth2ClientCallback/facebook/
   • https://m.{domain}/Api/Member/Oauth2ClientCallback/facebook/
5. After saving, click the toggle button at the top of the screen to change the status from In Development to Live, then select Mode Switch in the pop-up window.
6. In the Dashboard, click Show under App Secret to view your code.
7. Due to Facebook’s stricter app review process, apps in Live mode may revert to Development or become disabled.
   If this occurs, check the reason in NotificationsInbox.
