Facebook Messenger

Deploy an AI agent to Facebook Messenger.

Requires a Facebook account with admin access to a Facebook Business Page.

Publishing to Facebook Messenger lets your audience interact with the AI agent — and later a live agent — in a Messenger thread.

In the agent's Publish tab, create a Messenger channel or select an existing one to open its settings.

Message delivery

If Facebook rejects a message the AI agent sends on this channel, Proto marks the message as failed to send rather than showing it as delivered. A live agent who opens the conversation in the Inbox can see that the AI agent's message didn't reach the person.

Quick replies

Facebook only shows this button when the recipient has a shareable value on their profile; when it can't be shown, the AI agent still delivers the question as plain text so the person can type their answer.
