Consumer to Business Calling

Updated: Apr 19, 2026

Consumer to business calling lets your app handle inbound VoIP calls from consumers on Messenger. When a consumer calls your Page, you receive a connect webhook and have 60 seconds to accept the call.

Before you begin

Complete the setup described in the Calling overview

Subscribe to the calls webhook field

How it works

Receive a connect webhook — A consumer initiates a call from the Messenger app

Accept, reject, or let it ring — You have 60 seconds to respond with the accept API and an SDP offer

Establish the WebRTC connection — Apply the SDP answer from the API response to your local peer connection

Handle call events — Receive terminate webhooks when the call ends
