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”
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
