# Webhook overview

> Outbound HTTPS webhooks from 1Funnel to your endpoints.

<Warning>
  **Developer Preview**

  This documentation describes the upcoming 1Funnel External Integration API.

  The documented API endpoints and authentication services are not yet available
  for public integration.

  You can explore the API specifications, request and response schemas, webhook
  events, and integration guides.

  Sandbox and production availability will be announced separately.
</Warning>

1Funnel delivers approved business events to customer-managed HTTPS endpoints.
Delivery is at-least-once, unordered, and signed with DEC-WH-S01.

Inbound webhooks (your system calling 1Funnel event ingress) are not part of
this Developer Preview catalog.
