I built a converter for some of my users to use, that will take our list of customers to charge for the day from an XLSX file to a approved CSV file. I have this working for the most part, but I am having one issue. Reading documentation for the transaction upload, it states that you can use the last 4 or the masked credit card. My converter is going to our Sandbox and getting the credit card information, I have tested with the masked and just the last 4, but when I do the upload with either of those I get an invalid credit card error. If I put in the full credit card number it works fine. Am I missing something? Or do you have to use the full Credit Card number?

For charging a credit card a full card number is required.
For a refund (credit), you may use the last 4 digits of a card that you had previously charged.
I hope this helps!
