x_currency_code
Getting a 3,1,39 on my test account. So maybe it something you can't test?
Response Reason Text: The supplied currency code is either invalid, not supported, not allowed for this merchant or doesn’t have an exchange rate.
Integration Team Suggestions: There are two possible causes of this error:
- This error may occur if you use the field x_currency_code in your scripting, and you are setting it to a currency code other than "USD". At this time Authorize.Net only supports US currency. In this situation, processing transactions in US dollars should work as expected.
- This error may occur when an Authorize.Net Gateway Account is created without a valid Currency ID. In this situation, processing transactions is not possible in either your scripting or through your Virtual Terminal, regardless of the currency you choose.
If you encounter this error even when processing transactions in US dollars, please call the Authorize.Net Inside Sales team at 866-437-0476 and request a new Authorize.Net Gateway Account at no additional cost.
