Custom Integrations
Track conversions from any platform that is not in the AnyTrack Integration Catalog. Start here to decide whether a custom integration fits, set up the postback URL, and look up every parameter the endpoint accepts.
AnyTrack supports a large library of native integrations in the Integration Catalog, and new platforms are added regularly. When the platform you use is not listed, a custom integration lets you track its conversions yourself using a webhook or postback URL, then send them to your ad platforms through the Conversion API.
This page is the hub for building one. Follow the three steps below in order: decide whether it fits, set it up, then look up the parameters you need.
How a custom integration works
Section titled “How a custom integration works”Every custom integration wires the same chain. Each link has to hold, or the conversion never reaches your ad platforms.
- A visitor lands on your site from an ad. The AnyTrack Tracking Tag collects the click ID (
atclid) and the UTM parameters, and stores them as first-party data for the session. - The visitor engages, for example clicks an affiliate link or submits a form. AnyTrack’s AutoTag feature replaces the
--CLICK-ID--placeholder in your links and form fields with the realclick_id. - Your platform stores that
click_idagainst the customer, cart, or lead record so it survives to the conversion. - When the conversion happens, your platform sends it to your AnyTrack postback URL, including the stored
click_id. - AnyTrack matches the conversion to the original click and sends it to your ad platforms (Meta, Google Ads, TikTok, and others) through the Conversion API.
The decision guide walks this chain in more depth so you can tell whether it is within reach before you start.

Platform-specific walkthroughs
Section titled “Platform-specific walkthroughs”If your platform is a CRM, a form builder, or an eCommerce store, start with the matching walkthrough. Each one uses the same setup above, applied to that platform.
