DataLayer for Google Tag Manager
How To Configure
DataLayer for Google Tag Manager

Affiliate sales tracking with Magento + Google Tag Manager + Google Analytics

Please Note: The settings below require our Datalayer for Google Tag Manager for Magento and some features also require our Enhanced Ecommerce extension.

All Page View

Set cookie if user Affiliate user (site.com/?ies=abc123)

Tag Configuration
  Tag type : Custom Html

Trigger Configuration
  Trigger: All Pages

HTML

<script>
require(['DataLayerApi'], function (dataLayerApi) {
    var dataHelper = dataLayerApi();
    
    <!-- set cookie -->
    var urlKey = 'ies';
    var cookieName = 'affiliate_tracking';
    var lifetime = 60 * 60 * 24 * 30; // 30 days
    dataHelper.saveTrackingCodeIfKeyExist(urlKey, cookieName, lifetime);
});
</script>

To push the data to GA you can implement it in 1 or 2 ways

Purchase

####### Rewrite the data layer before sending the information to GA

Tag Configuration
  Tag type : Custom Html

Trigger Configuration
  Trigger: All Custom Events
  Event Name : purchase

HTML

<script>
require(['DataLayerPurchaseApi'], function (dataLayerPurchaseApi) {
    var purchase = dataLayerPurchaseApi();
    var cookieName = 'affiliate_tracking';
    var cookieValue = null;
    var data = {
      event: 'affiliatePurchase'  
    };
    
    if (cookieValue = purchase.getTrackingCodeIfKeyExist(cookieName, true)) {
        data.ecommerce =  {
            'purchase': {
                'actionField': {
                    'affiliation': cookieValue
                }
            }
        };
     }

    window.dataLayer.push(data);
});
</script>

Please Note: You will need to change your “purchase” event for tracking of order placement to ‘affiliatePurchase’, since it will take a few millisecond to load
