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.
- 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.
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.
