Documentation

1. go to you google tagmanager instance

2. go to the "Templates" section

3. look for the Eulerian Marketing Platform - GTM SS template in the gallery

4. create new template

5. the template is imported you just need to configure with the proper subdomain from the third-party tracking url

   5.1 example : if you tracking domain is : https://et1.eulerian.net the targetHost is et1.eulerian.net

   5.2 example : if you tracking domain is : https://io1.eulerian.net the targetHost is io1.eulerian.net

   5.3 example : if you tracking domain is : https://sdf475.eulerian.io the targetHost is sdf475.eulerian.io

6. set the consent mode configuration, one of the three options :

   6.1 Consent is handled before us being called -> set the enoepm=1 parameter

   6.2 Consent through pmcat by providing the list of consented categories for the current call

   6.3 Consent through TCF, in this case the TCString needs to be provided through a custom variable.

7. save the template

8. trigger the template with client = GA4 and on all events + custom events purchase / generate_lead.

9. publish the modifications -> you are now live !

Which events are mapped

global mapping

The following global parameters are always provided to each call sent to us as long as they exists in the original datalayer :

• page_location mapped to url
• page_referrer mapped to rf
• screen_resolution mapped to ss
• ip_override mapped to ereplay-ip
• user_agent mapped to ereplay-ua
• client_id mapped to euidl
• currency mapped to currency
• user_id mapped to uid
• user_data.sha256_email_address or user_data.em mapped to email

For each call we auto-copy all additionnal parameters of the event prefixed by ga-

page_view

Standard call done

purchase

A transaction is registered in this case :

• transaction_id mapped to ref
• value mapped to amount
• items mapped to product array & product params are prefixed by ga-

add_to_cart

Products listed in the items array are added to the current cart.

remove_from_cart

Products listed in the items array are removed from the current cart.

view_item

Product page is viewed and the first result of the items array is sent to Eulerian.

generate_lead

A lead is registered in this case :

• transaction_id mapped to ref, if not available a random ref is created
• value mapped to amount
• items mapped to product array & product params are prefixed by ga-

custom events

Custom events not listed above are directly sent to actions/goals for further processing in the platform.

MULTI-EVENTS

As GTM can trigger multiple events and hence our tag it can result in multiple calls on our end that can inflate the stats.

To avoid this make sure :

• you only trigger the Eulerian GTM SS only for the event you want to track
• avoid multi-event call on a single page : page_view -> view_item -> user_engagement for example only trigger on view_item if exists for example.

WARNING

By setting up a data-collection in server-side mode like this one, you'll loose all access to the initial web-browser. This means that some functionnalities of the Eulerian Marketing Platform won't be available because of the server-side integration, for example and not limited by :

• Heatmap
• Post-impression tracking
• Client-Side TMS
• Identity sync for IdGraph, CookieSync, etc...
• Real-Time access to current status of the user through javascript client-side API
• Privacy Sandbox integration
• Client-Hints management
• and probably other use cases

So make sure you know what you are doing and know what you want to achieve.

SUPPORT

We provide limited support through our free offering, if your setup is more complex we can provide consulting expertise and/or work with your expert agencies of your choice. This means that the current plugin works for most cases but not all cases, so please understand your own setup and make sure it makes sense regarding what we are collecting so that you can take the most of our platform. Enjoy !
