Solution to the Shopify Checkout Extensibility Problem

Starting August 28, 2025, scripts can no longer be placed on the Thank you and Order status pages, where previously everyone placed their data layer. Instead, you must now use customer events, which are isolated, meaning you must place your code within these events. Because of this isolation, you can no longer connect to web preview mode. However, Server-Side preview mode still works. The new TAGGRS Data Layer plugin not only fixes the problem of placing the data layer on the Thank you page, but also simplifies the implementation process of adding a data layer on your Shopify store.
