  title: Partner Event Notifications API
  version: '16'
  description: 'Event Notifications (also known as webhooks or postbacks) are HTTP requests that **impact.com sends to your server** in real time when relevant events occur — actions tracked, clicks credited, status changes, and so on.


    This is an **inbound** integration: you configure a URL in your impact.com account, and impact.com fires HTTP requests at that URL when events happen. You don''t call any impact.com endpoint to receive notifications.


    **How it works:**


    1. In your impact.com partner account, configure an Event Notification URL.

    2. Use placeholder tokens like `{CampaignId}`, `{ActionId}`, `{Status}`, `{Payout}` in either the URL (for GET delivery) or the JSON request body (for POST delivery). impact.com substitutes the real values at fire time.

    3. impact.com calls your URL whenever a matching event occurs.

    4. Your server returns a `2xx` response to acknowledge receipt. Non-`2xx` responses are retried by impact.com.


    This spec documents the **shape of the request impact.com sends to your server** — it is not an endpoint you call.
