An Apollo Event indicates that some key action has taken place on your website or mobile application that requires data to be collected. Some examples of Apollo Events might include Product Added to Cart, Checkout Started, Form Submission Succeeded, CTA Link Clicked, etc. When one of these actions occurs, there are various metrics and attributes that may need to be collected through tagging by developers. For example, during the Product Added to Cart Apollo Event, a developer may need to send the following data: Product ID, Product SKU, Product Price, Cart Addition Counter, etc. Using Apollo Events, your organization can configure your implementation to make sure you are collecting the data that you need to satisfy your business requirements when these Apollo Events occur.
