Custom pages

Topic summary

Shopify app developer is trying to add a redirect button on the post-purchase “Thank you”/order status experience using a Checkout UI extension (Checkout UI Addon). On some India-based stores using a 3rd-party checkout, the app can still inject into a customized version of Shopify’s Order Status page. However, with a newer checkout flow, some stores show a different final “thank you” page variant (example order URLs from two stores are provided, plus a screenshot), which appears to be a modified Shopify-hosted page. The developer cannot locate the template or configuration point for this page variant, so they can’t enable their extension there. They ask for help from a Shopify developer to identify where this page is defined and how to configure their addon to display the redirect button on it. No resolution is present yet; the question remains open.

hi, our shopify app adds a redirect button to the thank you page of a shopify website using our Checkout UI Addon.
Some websites in india use 3rd party checkout which load a customised versions of the ‘shopify Order status’ page - we can also add here using our Checkout UI Addon.
the problem is with some new checkout using this new variant page as their last page to thank shoppers -

(showing from 2 different stores)-

( Thank you! - Korakari Timeless Fashion | Kolhapuri Chappals | Punjabi Jutties - Checkout )

( Thank you! - Frankshop - Checkout )

These 100% shopify pages modified. We cant seem to find the template for these page, where we can then configure our addon. any shopify coder please help.

Attached is our add on setting to give an idea what we need to show.
