Issue with "Added to Cart" trigger – "No add to carts found" error

Hi ​@e-comm,

What e-commerce integration are you using, or are you using a custom integration? Are you attempting to create the flow with the custom Added to Cart event (gear icon) or an integration-specific Added to Cart event (for example, with the Shopify icon)?

Either way, the most likely cause of the issue is that no Added to Cart events have been sent from your store to Klaviyo because nobody that Klaviyo is able to track has added an item to their cart yet. For example, the Shopify-branded Added to Cart event tracks when somebody adds to cart after they:

• Submit a Klaviyo form
• Submit a Shopify form
• Enter their info on the checkout page
• Log into their Shop account on the checkout page
• Log into their customer account on your store.

Have people taken these actions and then added items to their cart? If you’re on Shopify and they have, and you’re still not seeing this event in Klaviyo, let me know.

"Hi there,

Thanks for the clarification. To answer your questions:

1. Integration: I am using the official Shopify integration.

2. Event Type: I am attempting to use the native Shopify 'Added to Cart' event (the one with the Shopify icon).

3. Identification: I have tested this myself by identifying first (submitting a Klaviyo form and clicking through an email), but the event still does not trigger in my activity feed or the flow builder.

The catch: I am using a third-party app called Kaching Bundles for my 'Add to Cart' actions. It seems like the app's AJAX functionality is bypassing the standard Klaviyo tracking script.

I have already tried adding the standard Klaviyo 'Added to Cart' snippets to my product.liquid and theme.liquid files, but since the bundle app intercepting the button click, the event isn't being captured.

Could you confirm if there is a specific way to track 'Added to Cart' events when a third-party bundle app (AJAX-based) is handling the form submission? Or should I be looking into a custom event via the Track API?"
