Meta Verification & Webhook Handshake
MantionPlus utilizes Meta's official Graph API. When a customer comments on your reel or post, Meta pushes a real-time HTTP POST request to our secure webhook listeners. We process the payload in milliseconds and send a response back through the Instagram messaging channel.
Incoming Payload Structure
Below is the standard payload sent by Meta webhooks when a customer messages your professional account:
{
