we own a multi-vendor store, so we need to manage payment system (paypal or stripe) for each vendor.
- store is NOT multitenant... ONE store, many vendors
- each vendor has already own shipment system
- cart is LOCKED to first vendor product customer added (one cart = one vendor)
So, we need to manage payment system for each vendor, managing account settings.
On order, customer select payment option (paypal, for example), so system had to set correct transaction to portal payment.
