Expert Needed: Fix Shopify to NewsBreak Server-Side Postback Tracking (RedTrack Setup)

URGENT - need this done TODAY - IMMEDIATELY - from someone with EXPERIENCE - please read the whole ad We are looking for an expert tracking and attribution specialist to set up a 100% foolproof, server-side postback tracking system between Shopify and NewsBreak. Our Current Dilemma & Technical Environment: What we have: We already have Shopify, Server-Side GTM, and Stape live. The Problem: We tried standard GTM and default Shopify tracking, but live events are failing. Currently, Add to Cart and Add Payment Info / Initiate Checkout are completely dropping for real traffic. The Ghost Glitch: When we run a manual test inside the NewsBreak Ad Manager, the events show up as working perfectly. However, the second real live traffic hits the store, the data pipeline breaks, and NewsBreak receives nothing. The Solution We Want: We want to entirely bypass the browser glitches and route NewsBreak tracking through a dedicated tracker like RedTrack (or a similar high-performance affiliate tracker) to handle true server-to-server (S2S) postback URL mapping. Note: You will NOT need to alter our existing Stape/GTM infrastructure, as that is handling other data streams safely. Milestone & Payment Terms (Please Read Carefully): Because we have already had developers "successfully" pass the NewsBreak synthetic test while the live tracking remains completely blind, payment will only be released once we verify that Add to Cart and Purchase events are accurately registering from LIVE ad traffic, not just the in-platform test utility. Requirements: Proven experience with NewsBreak Ad Manager parameter mapping (__CLICKID__). Deep understanding of Shopify's secure checkout environment, customer event pixels, and Ajax/cart drawer theme interactions. Advanced experience setting up server-side postbacks via RedTrack, Voluum, or Everflow. If you know exactly why a setup passes an ad-network test but fails in the real world, please apply and tell us your strategy for fixing it!
