Hi @jacopoOrlando , I suggest reading this article: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener It explains the process and provides examples of how to implement event listeners using vanilla javascript (aka no libraries). You can then add this to your profile using a Javascript Code extension. Hope that helps

If it's just session should be pretty simple So  when new session starts create empty cookie or localstorage variableWhen an event happens you add the value to the cookie or localstorage variable using the  push() method.You can use the js extension modules in tealium to create this function, this is just pseudo talk because it is really hard to be anymore speicfic without something else to go on, if you have any code or scrennshots we can probably direct you better

Hello - have you reviewed this document on debugging Tealium?https://docs.tealium.com/platforms/javascript/debugging/it's a great place to start when debugging this kind of setup.

@billysballo Your problem is that product_category is not present in the data layer on the order confirmation page, only product_id.  Presumably, both product_id and product_category are present on the PLP and PDP pages, as well as the add to cart event? In that case, one approach is to "remember" the most recent product_id and product_category and then use this "remembered" value when incrementing the Tally on the confirmation page event, if the product_id there matches the most recently "remembered" product_id. You could either do this "remembering" client-side (using for example a Persist Data Value extension) or in AudienceStream (using for example a pair of visit String attributes) @aaqib Your solution works because you are able to directly work out the product_category based on the product_id, which I think is different to @billysballo 's problem.  To answer a question you had about extracting values from the tally, there is an enrichment available on Number that pulls out the value of a particular key in a Tally and stores it in the number.  You may find the following diagram useful - https://community.tealiumiq.com/t5/Universal-Data-Hub/AudienceStream-Visit-and-Visitor-Attributes-and-Enrichments/ta-p/23244

Hi iMetrics, Does the tag template support link events? You can view the following guide to check: https://community.tealiumiq.com/t5/iQ-Tag-Management/How-to-Check-if-a-Tag-will-Fire-on-View-or-Link-Calls/ta-p/5649

Hi @sujay_das  You could add an extension scoped to the tag whcih sets a "do not fire" cookie.  Then add a load rule which stops the tag firing if that cookie is present.  You'd need to be a bit clever about the expiration of the cookie (or maybe have an extension that fires on every other page that removes it if it is present). You could maybe use a window scoped JS object instead of a cookie, although you say the page is reloaded, so I'd guess that would mean the window object would get refreshed too. HTH Ben

This is suggestion from my side, Always try to add all the product varibale data layer when cusotmer click "add_to_cart" and persist those data layer till they give the purchase from their side. It would help us to track the revenue of each product. Also, it would help us to track how many products has been dropped off by the customer at the end of the purchse.
