This guide walks you through connecting a Facebook Page to Zavu so you can receive and reply to Messenger conversations, including Facebook Marketplace chats.

​
Prerequisites

  • A Facebook Page (personal profiles cannot be connected)
  • Admin access to that Page

​
Step 1: Open Messenger Setup

  1. Go to Senders in your Zavu dashboard
  2. Select your sender or create a new one
  3. In the Channels tab, click Add next to Messenger

​
Step 2: Connect with Meta

  1. Click Connect with Meta
  2. Log in with the Facebook account that manages your Page
  3. Grant the requested permissions (Page messaging and Page access)
  4. Select the Facebook Page you want to connect
  5. Click Save
The login popup must be allowed by your browser. If nothing happens, check your popup blocker.

​
Step 3: Webhooks (Automatic)

When you save the connection, Zavu automatically subscribes your Page to messaging webhooks. Inbound Messenger and Marketplace chats start flowing into your Inbox immediately — no manual webhook configuration needed.

​
Testing the Connection

  1. Open your Facebook Page (or a Marketplace listing on that Page)
  2. From another Facebook account, send a message to the Page
  3. Check your Zavu Inbox — the conversation appears with the sender’s user ID
  4. Reply from the Inbox or via the API:
const result = await zavu.messages.send({
  to: "24025631120151183", // User ID from the inbound message
  text: "Thanks for reaching out!",
  channel: "messenger",
});

​
Marketplace Chats

No extra configuration is needed for Marketplace: buyer messages sent from your listings arrive through the same Page messaging webhook as regular Messenger chats.
Meta may restrict programmatic access to Marketplace conversations for some Page types or regions. If Marketplace messages don’t arrive but regular Page messages do, verify your Page’s Marketplace access with Meta.

​
Auto-Reply with AI Agents

To answer Messenger chats automatically, configure an AI Agent on the same sender. The agent triggers on inbound Messenger messages and replies within the 24-hour window.
