Messenger integration

Your Facebook Page, answered by AI

People already message your Page. Connect it once and an agent trained on your documents answers them — with your team one click away for the conversations that need a person.

Connecting your Page

  1. 1
    Create a Meta app with the Messenger product
    In Meta’s developer console, add the Messenger product and link your Facebook Page. Generate a Page Access Token.
  2. 2
    Paste three values into Chat Cactus
    Dashboard → Integrations → Messenger: the Page Access Token, your App Secret, and a verify token you invent (8+ characters). The token is validated against your Page immediately.
  3. 3
    Subscribe the webhook
    Paste the callback URL from the dashboard into your Meta app’s Messenger webhook settings with your verify token. Meta’s verification handshake is handled automatically.

Honest note: while your Meta app is in Development Mode, it can only message admins and testers of the app — going live to the public requires Meta's App Review for thepages_messagingpermission. Budget for that review in your launch plan.

Support automation on Messenger

  • Inbound Page messages get grounded answers from your knowledge base, in Messenger's plain, conversational register.
  • Replies stay inside Meta's standard messaging window and under Messenger's length limits — the agent is tuned for the channel.
  • Every conversation is in your dashboard with the full transcript, alongside your other channels.
  • Escalated chats pause the AI; your team replies from the dashboard and the customer sees a normal Page message.

Pre-sales questions, answered while they're hot

Page messages are often pre-sales: "do you ship to Ireland?", "is there a student discount?". The agent answers from your documents in seconds — while the buyer is still looking at your Page — and the full transcript sits in your dashboard so your team can pick up any conversation with complete context, or take it over live through escalation.

Frequently Asked Questions

What do I need from Meta?

A Meta app with the Messenger product added, connected to your Facebook Page. From it you take three values: the Page Access Token, the App Secret, and a verify token you choose yourself.

Why does my bot only answer me and not customers yet?

Meta’s rule, not ours: while your Meta app is in Development Mode it can only message the app’s admins and testers. Messaging the general public requires passing Meta’s App Review for the pages_messaging permission. The integration works identically before and after — review just widens who can talk to it.

Can the bot message people first?

No. It replies to people who message your Page, inside Meta’s standard messaging window. No cold outreach.

How are webhook calls secured?

Meta’s subscription handshake is verified against your chosen verify token, and every delivery is checked against the app secret’s signature before processing. Page echoes of the bot’s own messages are dropped so it can never loop.

Does escalation work on Messenger?

Yes. Escalated conversations mute the AI and notify your team; a teammate’s dashboard reply is delivered to the customer as a normal Messenger message from your Page.
