Order summary

The order summary area on the Thank you page displays the purchased line items and order totals after the buyer completes their order. Extensions in this area help merchants build post-purchase engagement by surfacing product-specific instructions, review prompts, and follow-up actions alongside the order details.

The cart line item target doesn't render for custom line items belonging to draft order invoices.

Anchor to Line item targetsLine item targets

Use these static extension targets to extend the order summary line items area on the Thank you page. These targets support the full checkout component set, including form fields, banners, images, and interactive elements. The examples demonstrate using the Order API for order data and API properties for reading checkout state.

Anchor to Thank you cart line item ,[object Object]Thank you cart line item target

purchase.thank-you.cart-line-item.render-after

Renders on every line item in the order summary on the Thank you page, inside the details under the line item properties element. This target is instantiated once for each item in the order. To selectively show content for specific items, inspect the cart line data from target and return null for items where your extension doesn't apply.

This target receives additional cart line item properties that provide the specific cart line through the target property with access to merchandise details, quantity, cost, attributes, and discount allocations.

The Order API provides read access to order data, including the order number and whether it's the buyer's first order. Extensions also have read access through API properties to checkout state, including shop information, buyer identity, cost breakdowns, and cart lines. Write access isn't available on Thank you page targets because the order is complete.

Anchor to Thank you cart line list ,[object Object]Thank you cart line list target

purchase.thank-you.cart-line-list.render-after

Renders once after all line items in the order summary on the Thank you page. This target appears once per order, unlike the cart line item target, which is instantiated for each item.

The Order API provides read access to order data, including the order number and whether it's the buyer's first order. Extensions also have read access through API properties to checkout state, including shop information, buyer identity, cost breakdowns, and cart lines. The Storefront API is available through the query method for fetching additional data like product recommendations. Write access isn't available on Thank you page targets because the order is complete.
