Hi folks, I'm new to these parts, so please forgive me if these questions are basic.
I've been tasked with developing an external payment app for a client. I've found the Processing a Payment doc, specifically the payments app flow.
While this flow makes 100% sense in a regular store checkout process, what I'm not clear on is how this would be adapted for accepting a payment for a draft order?
In the draft order scenario, a merchant could be taking an order over the phone. In such a case, does Shopify still need to make the request to the payments app, which returns the redirect URL? And if so, how does the merchant send the redirect URL to the customer over the phone, in order for them to capture their credit card details?
Any assistance/links to docs/examples would be greatly appreciated.
