Google Analytics (gtag.js): Product List Name doesn't appear but other fields do

Question

I'm implementing GA Enhanced E-commerce using the new gtag.js library. I want to send information about product impressions and product clicks, following the documentation here: https://developers.google.com/analytics/devguides/collection/gtagjs/enhanced-ecommerce.

Everything works (I can see the data in GA), except for Product List Name.

The docs seem to be inconsistent in naming the property (sometimes it's called "list" and sometimes "list_name") and none of them worked for me.

Here's my (simplified) code:

deals = [           
  {
    "id": "18",
    "name": "Some product",
    "list": "All Deals", // also tried "list_name" here
    "category": "Multiplatform",
    "list_position": "1",
    "price": "18,39",
    "currency": "EUR",
    "product_url": "https://www.amazon.com/someproduct",
  },
  ...
]

...

// on page load
gtag('event', 'view_item_list', {
  "items": deals
});

...

// on click
gtag('event', 'select_content', {
  "content_type": "product",
  "items": [
    deals[0]
  ]
});

All the data successfully make their way to GA, but Product List Name shows (not set), no matter what:

Thanks for any idea on how to fix/debug this!

Answer 1

there is an error/mistake/inconsistency in gtag documentation:

• you should use list_name instead of list

it works as expected with list_name

---

!!! DO NOT USE gtag as it does not send list_name value with events such as select_content and view_item

in short, query parameter pal (Product Action List) for collect call via gtag is not included, when using gtag — this is a major error comparing to analytics.js implementation.

Answer 2

You can send 2 events, when adding to cart from any list:

gtag('event','view_item',deals); gtag('event','add_to_cart',deals);

name of list must be set in list_name.

deals = [{"id": "18","name": "Some product","list_name": "All Deals", ...}]

Then it works fine.
