What is an API?

API stands for application programming interface. It’s a set of programming instructions that allows one application to integrate and work with another.

Our API was created to integrate with challenger banks, MSBs and fintechs that need to make and receive frequent international payments. It consolidates, automates and streamlines the entire international transfer process.

The RationalFX platform

International transfers are complicated. But we’ve spent over 15 years building relationships with banks and money services businesses (MSBs) across the world to make sure they don’t have to be. All that experience, all those relationships, are built into our online payments platform. It’s available 24/7 and allows customers to make payments to over 170 countries in more than 50 currencies.
