Google Analytics ecommerce sends only last item in transaction

Question

I'm using Google Analytics to track page views and transactions. The problem is that the ecommerce tracking only sends the last item added.

Here's the code that I'm using:

<script type="text/javascript">
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

    ga('create', 'UA-XXXXXXXX-1'); // fake code here
    ga('send', 'pageview');

    ga('require', 'ecommerce', 'ecommerce.js');

    ga('ecommerce:addTransaction', {
        'id': '31887',
        'revenue': '152.80',
        'shipping': '15.00',
        'currency': 'RON'
    });

    ga('ecommerce:addItem', {
        'id': '31887',
        'name': 'Product 1 ',
        'price': '94.90',
        'quantity': '1'
    });

    ga('ecommerce:addItem', {
      'id': '31887',
      'name': 'Product 2 ',
      'price': '57.90',
      'quantity': '1'
    });

    ga('ecommerce:send');
</script>

The code above should send 2 items but it only sends Product 2. Below are the requests that get sent:

As expected only the last item is being shown in the Google Analytics panel. The code seems right in every respect according to the Ecommerce Tracking Docs.

Any help on this would be greatly appreciated.

Answer 1

Try specifying a unique SKU for each item -- with ga.js analytics, if you added multiple items with the same SKU, only the last would be recorded, just like you're seeing.

If you don't have a product SKU, use the product name.
