Hey there! Not a developer here, but I have an understanding of what you're trying to do. At this time, it's not something we offer, in fact, this is the first time I've heard a request such as this!
It doesn't sound like something we'd plan on doing because it's a departure from our core business model of helping people to build dropshipping stores and brands online, but as I said, I'm not a developer. It's definitely something I'm going to speak to someone about to get some more context.
The only form of payment we offer is for our merchants to pay with major credit cards and as far as I know, there aren't any plans to change that in the near future. If you'd like to continue this conversation and have an Oberlo customer success manager reach out to the developers on your behalf, would you be kind enough to email us at firstname.lastname@example.org so we can follow up with you?
