Customers can sign in with Facebook. Like Google sign-in, it creates a normal WordPress Subscriber account.

• A Meta for Developers account.
• A privacy policy page.
• A page that explains how a customer can delete their data.

1. Open Settings → VisionScaper and scroll to Sign in with Facebook.
2. In Meta for Developers, choose My Apps → Create app. Use the use case “Authenticate and request data from users with Facebook Login”. Follow Meta’s current instructions.
3. In Facebook Login → Settings, add the address shown on the VisionScaper screen to Valid OAuth Redirect URIs. It is your home address followed by ?dreamscaper_oauth=facebook.
4. Under App settings → Basic, add your privacy policy address and a data-deletion instructions address.
5. Switch the app to Live.
6. Copy the App ID and App secret.
7. Paste them into Facebook App ID and Facebook App secret in VisionScaper.
8. Press Save Changes.

The scope is email,public_profile. If a Facebook account has no email, VisionScaper makes a placeholder email and the app asks the customer for a real one.

• For the data-deletion address, your privacy page can say customers can delete their account in VisionScaper by choosing Delete account from the account menu. That is a real button in the Designer.
• Test with a second Facebook account that is not an app admin once the app is Live.
• The sign-in button only appears when both ID and secret are saved.

• “That sign-in option isn’t set up yet.”: a box is empty.
• “We couldn’t read your account details. Please try again or use email.”: Facebook returned no profile. Check that the app is Live and permissions are granted.
• A staff member sees “Please sign in to staff accounts with a password.” This is deliberate.
• A redirect error from Facebook: the address in Meta does not match the one shown in VisionScaper.

• Google sign-in for customers
• API keys and services checklist
• Customer records, data export, erasing and privacy requests
