Ecommerce value and item price/discount

[jochemep]

Hi @jissereitsma,

I am currently testing version 3.9.12 for a project. Unfortunately, the implementation is not yet correct.

As an example, I will use the purchase event along with its accompanying documentation, but much of this also applies to other events.

The parameter value is incorrect when a cart discount (discount code) is active. Value reflects the price before the discount, but it should reflect the price after the discount. It is already exclusive of VAT, which is correct.

The item parameter price should be exclusive of VAT and discount. Currently, it is still inclusive of VAT, and when a cart discount is applied, it also includes the discount (whether this is possible or necessary, I cannot say.). The discount can be included in the item parameter discount.

At this moment, it is impossible with the current data layer to pass the correct purchase value to GA4 and Google Ads when a cart discount is applied.

I hope this information is helpful. Let me know if you have any further questions about this.

Could you perhaps work on a PR for this? I currently lack the time to work on this. Note that this is just a voluntary project to help people with a free transparent GTM extension. If you make money with Magento, collaboration is appreciated here.

And note that version 3.9.12 is outdated.

Hi @jissereitsma ,

Thank you for your response, and I completely understand that you're asking for help. Unfortunately, I’m not a (Magento) developer myself. I work as a marketer on a project that uses your valuable GTM module. I’ll ask the merchant if they can update the module and have the web developer create a PR. Please see this feedback as my contribution to the project.
