Setting up GTM to send Recos Datalayer Events

The goal is to configure GTM so it will send Analytics events based on the Recos Events pushed in the DataLayer. If we have Publisher access to GTM, usually the TSM does this setup for the client directly.

Create a trigger

Go to trigger

Trigger > new

Create a new trigger:

Title = Recos - trigger Trigger type : Custom Event Event name = ab_recos Select: use regex matching All custom events SAVE

Tick “Use regex matching”

Create the 6 variables

Go to variables :

Scroll down to reach “User-defined variables” > New

Create all the following variables with the following data layer variable name : Fill the title (ex: action_id) and the datalayer variable name (ex: recos.action.id) Variable type = Data Layer variable

• action_id → recos.action_id

• reco_id → recos.reco_id

• reco_name → recos.reco_name

• item_id → recos.item_id

• item_ids → recos.item_ids

• debug_mode → recos.debug_mode

Create the tag

Name: Recos - Event GA4 - recos Tag configuration > Google Analytics > GA4 event

GA4 Event:

Fill the measurement ID: to be found in the GA4 of the client

—> Go to the GA4 of the client GA4 > Admin >

Data Stream:

Copy the Measurement ID:

Paste the measurement ID in GTM: and event Name = ABTastyRecos

Create and add all the following event parameters with the previously created variables : Click Event Parameters > Add parameter

ex: action_id Click on Value +

Find the variable created previously:

Do it for all 6 event parameters and values, as created previously:

• action_id

• reco_id

• reco_name

• item_id

• item_ids

• debug_mode

Where each variable is defined this way Select the trigger:

Select the trigger Recos - trigger created before

Publish

SAVE Workspace changes are 8: 6 new variables, 1 new trigger, 1 tag. Give a name (ex: ABTasty reco tracking event)
