A client of mine represents a credit card processor (ISO) and wants to integrate with Wix for their customers.
Everything I can find lands me on this page: https://support.wix.com/en/article/requesting-additional-payment-providers where I have to request that a new processor is added. We just want to build our own and add in a "hook" to process our own card and send the result back to wix stores.
Is this possible to do? Is there an API or documentation on how to do it?
