Browser-based tracking is increasingly unreliable. Ad blockers defeat pixels before they load. iOS App Tracking Transparency limits cookie-based tracking. Safari’s Intelligent Tracking Prevention caps third-party cookie lifetimes. The result: conversion events vanish, attribution gaps widen, and ad platforms optimize on incomplete data. Server-side tracking captures events outside the browser — at the edge or in your backend. Upstack does this via an edge pixel plus Shopify webhooks. The lightweight pixel fires first-party requests to Cloudflare’s edge, so ad blockers cannot strip the tracking call. Purchase and checkout events are also confirmed server-side via Shopify webhooks, giving you near-complete coverage. Most stores recover 20–40% of events that client-side scripts miss.Documentation Index
