Setting up the Webhook

  1. Configure the Webhook URL:
    • In your Facebook Developer portal, navigate to the “Messenger” section of your app.
    • Under the “Webhooks” tab, click on “Add Webhook”.
    • Enter the publicly Cambodia Phone Number List accessible URL of your webhook endpoint, which will receive the incoming messages from Facebook Messenger.
    • Select the events you want to subscribe to, such as “messages”, “messaging_postbacks”, and “messaging_optins”.
  2. Verify the Webhook:
    • Facebook will send a verification challenge to your webhook URL to ensure it’s a valid endpoint.
    • In your webhook handler, implement the logic to verify the challenge and respond with the correct verification token.

    • Send the response back to Facebook Messenger using the appropriate API calls.
