Quantcast Conversion API
The Quantcast Conversion API is a server-to-server integration that augments the browser-side Quantcast Live Tag. It accepts a JSON array of conversion events containing a conversion descriptor, a user object (browser token or user agent plus IP, optional hashed email, optional external ID), and an event object (labels, order ID, revenue, product category). It is designed to capture offline conversions, delayed sales, and conversions that occur outside of the browser, and to provide signal resiliency in cookie-restricted environments. The account ID is passed as the `a` query parameter.
