Holdfast: Checkout Pixels

Your thank-you page scripts stop working August 26. Holdfast rebuilds GA4, Meta and TikTok. On August 26, 2026 Shopify stops running Additional scripts on your Thank you and Order status pages. Purchase tags there stop firing, no error — your ad numbers flatten. Holdfast reads that box and rebuilds your GA4, Meta and TikTok tags as an official Web Pixel. GA4 also gets a server-side copy from your store, so an order lands even if the browser never fires. Only one copy counts. Other trackers it finds are listed with what to do. Meta and TikTok send from the checkout pixel only.
