Thanks for all your help so far. I have managed to get it working, although I am no longer working in Ionic but native Android. The video provided by Visa also helped a lot.
One last question, the exchange rates being provided by the API seems to be different from the one Visa provides? For example, changing from Russian Ruble to USD. The rates quoted by the API seem to be 0.0165 but the one at the site quotes 0.015994?
Foreign Exchange Rates API in Sandbox provides simulated data and not real-time data. Once you move to production you will be able to work with real data. The rate you will get in production will be correct and you can also markup on it before publishing to your customers.
Can you please provide me with your use case and what it is that you are trying to do? I'd really like to help you!
