Shopify Web Pixels
How web pixels work
Pixels are JavaScript code snippets that run on the online store and collect behavioral data, referred to as customer events, for marketing campaign optimization and analytics.
After you’ve created your web pixel and configured it to a merchant’s shop, your pixel is able to load in the shop’s online store. As a customer browses the online store, they’ll trigger customer events that are published to a Shopify data layer or event bus. Your pixel can subscribe to the events on this data layer and then transform the event payloads into a format that conforms to the requirements of your pixel’s data collection endpoint.
