Shopify Plus Stores Branch specific checkouts

I’ve been working on an app for Plus stores utilizing Checkout UI and wanted to test the app on one of the clients production stores on a dev branch. When I tried to edit the checkout, it took me to Market group checkouts which let me build a new checkout but I couldn’t find a way to assign it to that specific dev branch. Is there any way to customize a checkout for a specific branch so I can test this app before publishing?

Thanks, Caine

Hey @Caine - thanks for reaching out.

I checked on this, and there isn’t currently a way to assign a checkout customization to a specific dev/theme branch. Checkout customizations are scoped to checkout configurations and market-specific overrides, not theme branches.

For testing before making changes live, the supported paths would be:

  1. Use shopify app dev with a development store to test the Checkout UI extension during development.
  2. If you need a fully isolated production-like setup, a separate staging/development store is the safest route.

I definitely get that branch-specific checkout testing would be useful here, so I’m happy to pass this feedback along on our end if you’d like! Let me know if I can clarify anything further.
