# Standard storefront events and actions

Standard events and actions are a fixed set of event names and calls that don't change from one storefront to the next. A storefront dispatches an event when a commerce interaction happens, such as a buyer adding an item to the cart. An app or an AI agent calls an action to request a change, such as opening the cart.

Apps used to do this by parsing a storefront's DOM or intercepting `window.fetch`, which meant a separate integration for every storefront. Now one integration covers them all.

## Events

[Events](https://shopify.dev/docs/api/storefront-events-and-actions/events) are DOM events with a `shopify:` prefix, such as `shopify:product:view` and `shopify:cart:lines-update`. They cover page and product views, collection filtering, cart changes, and search.

## Actions

[Actions](https://shopify.dev/docs/api/storefront-events-and-actions/actions) are calls your app makes to read the cart, change it, or show it to the buyer, without needing to know how that storefront renders it. The same `openCart` call works for a drawer or a cart page.

Actions work out of the box on every Liquid storefront. Every action has a default behavior, and a storefront can override it.
