Facebook Messenger
Connect Facebook Messenger by authorizing CoPhrase on a Facebook Page through Meta OAuth — an official Graph API integration.
CoPhrase answers Facebook Messenger through Meta's official Graph API. You connect by authorizing CoPhrase on a Facebook Page — Messenger conversations belong to a Page, not to a personal profile.
What you need
- A Facebook Page for your business.
- An account with admin access to that Page.
Setup
Authorize with Meta
Start the Messenger connection in CoPhrase. Meta's OAuth flow asks you to log in and choose which Page(s) to grant access to, then shows the permissions being requested — reading and sending messages for that Page.
Pick the Page
If you admin several Pages, select the one whose Messenger inbox the agent should handle. One connection per Page.
Pick the agent
Choose which agent answers on this Page. Messages start arriving in your inbox.
Messenger arrives in a later wave
Like Instagram DMs, Messenger is gated on Meta's app review process, which runs on its own calendar. It ships in the channel-expansion wave, after the web chat widget, Discord, and WhatsApp.
The 24-hour window
Messenger enforces the same window as Instagram, and it works the same way:
- The window opens only when the customer messages your Page. Nothing you send opens or extends it.
- Inside the window: the agent replies freely.
- Outside the window: you cannot send a standard reply.
- You can never message someone first through this API.
The one extension: a Meta-approved tag lets a human continue replying for up to 7 days after the customer's last message — for handoff follow-ups. It applies to human replies, not to bot replies.
CoPhrase tracks the window per conversation. If it closes on a thread that still needs a reply, the inbox tells you why you can't send, rather than failing silently.

Things to know
Page comments are not Messenger. The agent answers DMs to the Page. Replying to comments on your posts (and turning a comment into a DM conversation) is a separate roadmap feature — not available at launch.
Messenger and Instagram are separate connections, even when the same business owns both. Each is its own channel connection with its own thread history. The person behind both, though, resolves to one contact if we can link them — so qualification the agent did on Instagram is available on Messenger.
Page roles matter. If you lose admin access to the Page, the connection stops working. Re-authorizing requires someone with Page admin rights.
