Refund using AIM

[nihirporecha]

Hi all,

I have been implementing Refund functionality for AIM. I have used the API dlls provided by Authorize .NET(programming language C# .NET).

So, the signature of Refund functionlity for AIM accepts three parameters.

1) Transaction id

2) amount

3) Card Number

Now, the question is can I skip the Card Number field? We are not storing the card information. So, I do not have the card information.

You only need to submit the last 4 digits of the credit card. If you didn't save these or get them from the customer, you can use the Transaction Details API to look up the transaction and retrieve them.
