Connecting Facebook Messenger lets you handle your Page’s conversations through the same Inbox as WhatsApp, Instagram, Live Chat, and SMS.
Before you start
- You must be an admin with access to the Facebook Page you’re connecting.
- The Page must be connected to your Meta Business Portfolio. Check the Business Portfolio settings to confirm the Page appears there before starting.
Connect the channel
- Go to Settings → Channels.
- Click Add Channel.
- Select Facebook (Messenger).
- Click Connect in the dialog.
This opens Meta’s Facebook Messenger onboarding flow, which may ask you to:
- Sign in to Facebook or confirm your account.
- Select the target Facebook Page.
- Authorize Heyy to send and receive messages on the Page’s behalf.
If you manage several Pages, double-check you’re selecting the correct one in the picker — the flow does not warn you if you select the wrong Page for this channel.
Disconnecting or deleting a Messenger channel is irreversible. Heyy will no longer send or receive messages for that Page, and existing conversations may be lost or no longer accessible. Export or back up anything you need first.
What Messenger is good for
Messenger follows the same 24-hour reply window as WhatsApp — see Conversation window.
