# Configure Messenger webhooks and all four required fields
## What do I paste into Meta?

A webhook is the address Meta calls when an event happens. Copy Callback URL and Verify Token from Mr. AI step 4. Verify Token is a handshake code, not your Page Access Token or App Secret.

*Callback URL and Verify Token fields in Meta. Actual Meta screen from the Arabic setup recording, 22 October 2026; private details removed. Menu language and layout may differ. Select to enlarge.*

1. Save Page and app credentials first. Open Webhooks or the Messenger webhook settings in your Meta app.
2. Select the Page object, not User. Copy the exact public HTTPS Callback URL and Verify Token from Mr. AI.
3. Paste both values and choose Verify and Save, or the equivalent action shown in your Meta app.
4. Enable messages, message_echoes, messaging_postbacks and messaging_optins for the Page webhook.
5. Return to Mr. AI step 5 and separately check the actual Page subscription.

messages receives customer messages. message_echoes receives messages sent by the Page, including human replies from Meta Business Suite. messaging_postbacks receives supported button actions. messaging_optins receives supported opt-in events.

> Enable the required fields in App Webhooks, then check the Page subscription in Mr. AI step 5. These are separate steps: Verify and Save alone does not confirm that your customer messages will arrive.

## Webhook recovery

### Verify and Save fails.

Copy Callback URL and Verify Token again from Mr. AI step 4 and confirm that you are using the intended Meta app. If you generate a new Verify Token, update Meta and verify again. If verification still fails, contact support with the visible error and step number.

### Should I add standby or messaging_handovers?

No. Mr. AI human takeover does not require Meta Handover Protocol.

### Webhook verified but messages are missing.

Check the Page subscription in step 5, then Meta permissions and public access. Send a new message from a separate customer account and check whether it reaches Chats; address verification alone does not test message delivery.
