Extensibility for delivery and shipping

You can customize and build additional functionality to delivery methods in Shopify checkout with the following methods:

• Extension points, using a checkout UI extension
• Delivery customizations, using a checkout function
• Local pickup, using a checkout function
• Pickup points, using a checkout function

If you're adding functionality or content to a delivery method, then you should use checkout UI extensions in extension points. There are static extension points located for all native delivery methods including shipping, local pickup, and pickup points.

The following example shows a custom field that collects delivery instructions and renders at the purchase.checkout.shipping-option-item.render-after extension point:

To hide, rename, or reorder shipping options, you must use a checkout function. Delivery customization functions are only applicable to shipping options and aren't compatible with local delivery, local pickup, or pickup points.

To create a local pickup customization, use a checkout function.

To create pickup point options, use Shopify CLI and a checkout function.
