# Can TiXel track events of an external Add To Cart button (that leads outside the store)?

## Introduction  
If you have replaced your **'Add to Cart'** button with an external link (for example to Amazon), you may want to trigger the **Add to Cart** event when visitors click the link.
However, due to the way **Shopify's Analytics** processes events, this action cannot be directly tracked as an **Add to Cart** event. This guide explains why this limitation exists.

## Understanding Shopify's Event Tracking  
TikTok's tracking system requires specific event data to be sent to TikTok in order for it to register an **Add to Cart** event. This data is generated **only when a product is added to the cart** within Shopify.

Since an external link (such as to Amazon) **does not pass Shopify's cart data**, TiXel does not receive the necessary information to trigger the event. A simple **click event** does not contain the required purchase-related details, making it **impossible to track** as an **Add to Cart** event.

## Conclusion  
Due to Shopify's analytics limitations, **the Add to Cart event cannot be triggered directly** through a simple link to Amazon or to other URL.
