I have found a post referencing a field for ARB called "x_currency_type", however the ARB API documentation does not reference anything about currency type. I also found a post that makes it clear that Authorize.Net ONLY supports USD.
I am confused. Does ARB support setting up recuring payments using the EURO?
If it does not support the EURO I would be interested in converting to USD in my application and then creating a recurring payment using the converted amount. I would also like to be able to use the API to update the subscription amount each month to adjust for conversion rates. Is this an acceptable use of the update API?
All of Authnet's APIs support only the US dollar.
