The challenge
A connector's whole job is to move data out of Shopify reliably — and in 2026 that means doing it on the sanctioned surfaces, not by injecting script tags. Add-to-cart events have to carry enough product and shopper context to be useful downstream, review data lives in a third-party app entirely, and any pipeline handling shopper identity has to satisfy Shopify's privacy webhook requirements before it can be listed at all.
