Pixels and customer events
Pixels are JavaScript code snippets that run on your online store or store checkout and are managed from the Customer events section in your Shopify admin. Pixels collect and pass behavioral customer data for marketing and reporting.
Customer events are actions taken by your customers that can help you understand how your customers are engaging with your business. Third-party services that are integrated with your store use the customer event data that they collect using pixels to optimize your marketing automations and analytics.
