The Currency Cloud, cross border payment as a service provider, has enabled developers to integrate international payment processing with an API: XBPConnect. Prior to the Currency Cloud, payment/invoice software required users to leave the platform and engage a third party to process an international invoice. The Currency Cloud allows cross border and multi-currency transactions from a single platform. The API allows developers to integrate the functionality into existing apps and platforms.
