Hi,
Yes. When you use HikaMarket, the customers go through the normal checkout of HikaShop and so they use the normal payment plugins.
There is no particular restrictions on this.
Some payment plugins can handle automatic dispatch for the fees to each vendor on the fly, like the Stripe connect plugin we also have on the marketplace, but you can still use normal payment plugins next to them. It's just that the fees won't be dispatched on the fly. You'll have to manually pay out the vendors from the backend of HikaMarket etc.
