ExtensionPoints

A UI extension will register for one or more [extension points](/docs/api/checkout-ui-extensions/extension-points-overview) using `shopify.extend()`. An extension point in a UI extension is a plain JavaScript function. This function receives some API for interacting with the application, and is expected to return a value in a specific shape. The input arguments and the output type are different for each extension point.
