Setup Meta Pixel for Purchases

I need a Meta Pixel correctly installed and configured on my Shopify store so every completed order fires a reliable Purchase event. The key metric I care about is website purchases, and I only need Meta to receive the order value and currency—no product-level or customer-level data for now. I already have a live Shopify checkout but the pixel isn’t reporting consistently, so your task is to place the pixel in the right theme files or through Shopify’s native integration, test it end-to-end, and verify that the Events Manager shows green for Purchase events. Deliverables • Pixel installed and firing on all pages that lead to checkout • Purchase event triggering after payment confirmation, passing order value and currency • Test events and diagnostics screenshots proving the setup works • Brief hand-off note explaining where the code lives and how to troubleshoot future issues
