We have a live application already which consist of embedded admin and in-store proxy parts. The proxy part allows customers to look for their orders and perform some actions on them.
Now we need to allow retailers to take additional payments from customers on their stores. Not the payments within the checkout flow, but additional payments. Let’s say, payment for the shpping label. The customer pays for it to retailer (while being on the store page) and then our application processes everything futher.
So it should be an additional payment to a retailer’s account.
And we’d like to capture it using Shopify payments from a retailer’s account, so we wouldn’t need to setup additional payment gateways anywhere, bother with additional accounts, etc.
Is it even possible? Does Shopify allow to initiate and process additional payments to retailer’s accounts outside of a normal checkout process with cart and products. Or the only option is to use a third-party payment provider?
