Duplicate Add to Cart event firing during Home Page View / Buy Now / Checkout flow

Shopify Apps
1

Hello Community,

I am facing an issue in my Shopify checkout flow:

  • On the home page view, the Add to Cart event is firing automatically.

  • When clicking Buy Now, the Add to Cart event is also firing.

  • When a customer first adds a product to the cart and then proceeds to checkout, an additional Add to Cart event is firing after checkout completion.

This is affecting the Add‑to‑Cart vs Checkout ratio and skewing performance metrics.

Has anyone else experienced this issue? Could this be related to theme code mapping or overlapping scripts from integrations (e.g., analytics SDKs, marketing apps)?
I would appreciate guidance on the Root Cause Analysis (RCA) and possible fixes to prevent duplicate event triggers.

Thanks in advance for your support!

An app could probably be interfering. Try putting off or uninstalling some apps and check if the issue exists.
