How to enable Checkout UI Extension on thank you page

Topic summary

A Shopify Plus user built a Checkout UI Extension to display line-item properties and configured three targets: purchase.checkout.cart-line-item.render-after, purchase.thank-you.cart-line-item.render-after, and customer-account.order-status.cart-line-item.render-after. Only the checkout target can be enabled in the checkout editor; the thank you and order status targets are not available.

Clarification confirmed the store is on Shopify Plus and using an app. No configuration issue was identified.

Latest update: The thank you and order status page extension points appear not yet rolled out. A Shopify newsletter notes the launch of checkout extensibility for those pages was moved from October 24, 2023 to November 7, 2023.

Interim workaround: For now, modifying the thank you page may only be possible by injecting custom JavaScript via settings/checkout.liquid.

Status: Pending platform rollout; resolution expected after the new launch date. An attached screenshot is referenced but not essential to the conclusion.

Hi, I created a Checkout UI Extension to display line-item properties at checkout.

I configured 3 extension target

  1. purchase.checkout.cart-line-item.render-after
  2. purchase.thank-you.cart-line-item.render-after
  3. customer-account.order-status.cart-line-item.render-after

But I can only enable the 1st target in the checkout editor only.

How do I enable 2 & 3? It seems there’s nowhere to enable them.

Hi,

Are you using Shopify plus and App for this?

Yes I am using Shopify Plus and App

Replying myself here.

My best guess is that these extension targets are not rolled out yet.

It is mentioned in Shopify newsletter but nowhere I could find in doc:

We are moving the launch of checkout extensibility on the thank you and order status pages from October 24, 2023 to November 7, 2023.

So for now it is only possible to modify thank you page through pasting JS in settings / checkout.liquid
