Hi there! So we have created 3 stores powered by Shopify in the backend & Next.js on the front-end. We run Search & Social ads so our issue is that all purchases source & medium are going to direct/none in Google Analytics 4 when we know they are coming from paid traffic.
Take a look at https://www.wofwoodward.com/ for instance. This is the link for the checkout button: https://west-of-woodward.myshopify.com/63618056443/checkouts/e791ec267a27fcea4d5873b867228754?key=3d3fdd7985b73c036f40f3edf7cfedcb&_gl=1tpd4in_gaMTQ1NDgwMTUwOS4xNjg5NjEyOTM0_ga_MR3EBDC0V2*MTY5MDgzNzU1Ny4yNC4xLjE2OTA4Mzc1NjAuMC4wLjA.&_ga=2.92775901.178622250.1690833676-1454801509.1689612934
And when we click on the checkout button, it redirects here: https://west-of-woodward.myshopify.com/checkouts/co/e791ec267a27fcea4d5873b867228754/information. We basically lose the parameters.
We’ve reached out to Shopify Support with no success. Could anyone explain the issues we are experiencing? Has anyone successfully integrated cross domain tracking with a Headless Shopify Store?
