Refund is not available for new payment app

[iurii_a]

We are a company developing new payment app for Shopify for BNPL payment processing. It's almost ready, and is installed for development store. We are able to pass checkout flow fully (https://shopify.dev/apps/payments/processing-a-payment). It works fine, we are able to see orders in "Orders" tab in development store admin.

But we can't complete refund flow (https://shopify.dev/apps/payments/processing-a-refund) due to "Refund" button is missing for these store/orders, only "Restock" button is presented.

We spent some time to investigate the reason for it, including discussion with Chat Support of Shopify without result. But we discovered several things:

• "Refund" button is not presented, despite of order is paid and fullfilled. "Restock" is presented

• If I click on "Restock", I could see order is considered as "free order". In case of proceeding with restock I could see message that refund for $0.00 was done for this order

• For some reason "Gateway" for this order is detected as "undefined" for this app, see screenshot below

• We can't see any concerns with https://help.shopify.com/en/partners/dashboard/managing-stores/test-orders-in-dev-stores - we have "Test mode" enabled for our payment app

What we would like to achieve:

• to see "Refund" button for order to be able to test refund flow according to https://shopify.dev/apps/payments/processing-a-refund
• to see "Gateway" as detected, and order as not "free order"

Any help or suggestions are appreciate! Thank you!

Has your problem been solved?

Yes. Some time after this post "Refund" button appear - no idea what was changed.

The root cause why "Refund" button is not available - payment app should be "Published" only. For unpublished payment app refund is not available, only restock button is available.
