Step 13. Enable Live Mode

⚠️ Important: Privacy Policy URL Required Before Taking App Live

When you try to switch your Meta Developer app from Development to Live mode, Meta may show an error such as “Invalid Privacy Policy URL”.

This happens because Meta mandatorily requires a valid Privacy Policy URL before allowing the app to go Live.

What you need to do:

1. Go to My Apps → App Settings → Basic.
2. Scroll to the Privacy Policy URL field.
3. Enter a valid and publicly accessible Privacy Policy page URL
   (example: *https://yourwebsite.com/privacy-policy*).
4. Click Save Changes.
5. Go back to the app dashboard.
6. Toggle the app status from Development → Live again.

Once a valid Privacy Policy URL is added, the app will move to Live mode successfully.

• Change the app status to Live to complete the integration.

Step 14. Generate an Access Token

Generate a Temporary Access Token (Only for Testing purposes)

• Generate an access token (a temporary token that expires in an hour).
• Add the following details to Pabbly ChatFlow in the Add WhatsApp Number dialog box:
  • Access Token
  • Phone Number ID
  • WhatsApp Business Account ID

Generate a Permanent Access Token

• Go to the Configuration section.

• Scroll down to the Permanent Token section.

• Click the provided link to Meta’s documentation on generating a permanent token.

• Follow the steps to generate a System User Access Token:

  1. Go to Business Settings.
  2. Click System Users.
  3. Click +Add, enter a System User Name, and assign an Admin or Employee role.
  4. Select the created system user and assign the necessary assets and permissions:
     • business_management
     • whatsapp_business_management
  5. Click Generate Token, choose the app, set token expiration to Never, and copy the token.
  6. Add this permanent token to the Add WhatsApp Number dialog box in Pabbly Chat Flow.
