Product_added_to_cart event not firing when cart-transform runs

Web Pixels

It looks like the product_added_to_cart event isn’t firing when the cart-transform function runs for items added through it.
Has anyone run into this issue before?

Hi @Pedro_Carrera

Is it only the `product_added_to_cart` event that isn’t triggering? Is my screenshot helpful to you?

Hi @kyle_liu !

Yes, in my case only `product_added_to_cart` is not triggering…. products are added by calling add.js endpoint with a custom app and cart-transform runs to merge the products (it is a bundle page). I am not sure why it is not triggering

Hi Pedro!

Are you adding multiple products to the cart in a single add.js request when this issue occurs?

Hi @Paige-Shopify !
Yes, two products and then the cart-transform does the merge operation to consolidate then in a single bundle product

Thanks for confirming.
I was able to replicate this when I’m adding multiple products together and it results in a merge as well.
This appears to be a gap in our Web Pixels API that we’ll need to address.

Thanks for reaching out about this! I’ll provide an update here once we’ve shipped a solution for this :slight_smile:

Hi @Paige-Shopify ! I am glad we have discovered this together :slight_smile:

Do you have any visibility on when it should be addressed and fixed? I am asking because not seeing ATC events during holiday season is quite critical for the whole business.

Thank you.

That’s completely fair.

At the moment, we don’t have plans to address this in the near term since there’s a workaround available. You can add the products to cart using separate add.js requests. While this does result in multiple add_to_cart events instead of a single one, it should still allow you to capture business-critical data.

So you are saying the most important event, other than Purchase, that should NOT require a work around, is not high on the list for holiday season??? Is that REALLY what you are saying???

Hi Eric,

I get where you’re coming from. Add to cart analytics is crucial, especially this time of year. To help us prioritize this correctly, could you share more about why the current workaround isn’t meeting your needs?
