Meta Pixel + Meta Ads + Shopify Expert- Conversion & Tracking Fix

My Meta Pixel has stopped firing on my Shopify store, so Meta Ads is no longer receiving the add-to-cart, initiate checkout, or purchase events it needs to optimise campaigns. I have already verified that the catalogue and product feeds are fine—the problem sits squarely with the pixel implementation or event setup.

Here is what I need from you. First, a quick audit of the current pixel and event setup in both Shopify and Meta Events Manager to pinpoint why no events are being sent. Next, a clean re-installation or troubleshooting of the pixel so that every standard and custom conversion event reliably fires, is deduplicated, and shows as “received” and “green” in Events Manager. Finally, I want a short validation period where you confirm via real-time testing and test events that everything lines up: the numbers in Shopify, Ads Manager, and Events Manager should match within an acceptable margin.

Deliverables (all must be met for sign-off):
• Pixel firing on view content, add-to-cart, initiate checkout, purchase, and any custom events we identify
• Verification screenshots from Events Manager showing active events with no warnings
• Brief hand-off document summarising what you fixed and how to maintain it

Please respond with a detailed project proposal that outlines your diagnostic approach, the specific tools or apps you might use (e.g. Facebook Channel app, GTM, Conversion API), and an estimated timeline for completion.
