​
Prerequisites

Meta updates Facebook and its developer tools frequently. The steps below describe what you need; for exact, up-to-date screens, see Meta’s Messenger Platform documentation.
1

Facebook Business Page

You need admin access to a Facebook Page. The dashboard method connects it for you via Facebook login — no developer app required.
2

Facebook App (CLI only)

Only needed for the CLI method. Create one at developers.facebook.com.
The dashboard connects Facebook via Facebook Login (OAuth) — you authorize Lua in a Facebook popup and pick your Page there, so there’s nothing to copy or paste. Use the CLI method if you’d rather supply a Page access token manually.
1

Open the dashboard

Or visit https://admin.heylua.ai.
2

Open your agent

Click Agents in the main side navigation, then select your agent’s card.
3

Add a channel

Click the + (plus) icon to add a channel, then choose Facebook.

4

Accept terms & connect

Tick the box to accept the Terms of Service and Privacy Policy, then click Connect.
5

Authorize with Facebook

A Facebook login popup opens. Log in, select the Page you want to connect, and grant the messaging permissions Facebook requests. When the popup closes, the channel is connected.
This popup is Facebook’s own UI and changes periodically. See Meta’s Messenger Platform documentation if you get stuck.
6

Connection success

Facebook appears in your connected channels and is ready to receive messages.
