Provider guides
Meta / Facebook
Meta platforms like Facebook, Instagram, and WhatsApp confirm a webhook subscription with a handshake before they send you anything. Webhooker answers that handshake for you, so connecting is the same paste-the-URL step as any other provider.
The subscription handshake
When you save a webhook in Meta's dashboard, Meta sends a
GET request to your URL with a
hub.challenge query parameter, and expects that exact value
echoed back. Webhooker responds to that request on your ingest URL
automatically — you don't need to stand up a separate endpoint for it.
What to do
-
Copy your source's ingest URL,
https://webhooker.eu/in/<token>. - Paste it as the Callback URL in Meta's webhook configuration and set your verify token.
- Save. Meta's verification call succeeds against Webhooker, and real events start flowing to your destinations like any other source.
