Facebook Webhooks

Facebook webhooks are delivered through the Meta Graph API and are shared by Facebook Pages, Instagram, Messenger, WhatsApp, and other Meta products. They do not follow the Standard Webhooks spec.

Using WhatsApp? The WhatsApp Business Platform shares this exact Meta mechanism but has its own events, payloads, and setup — use the dedicated whatsapp-webhooks skill. This skill covers Facebook Pages, Instagram, and Messenger. The shared handshake + X-Hub-Signature-256 algorithm is documented once, canonically, in references/verification.md.
