Return Funds to a Customer

This code steps you through the process of refunding payments that have been made on settled transactions.

There are three outcomes when processing credit card transactions:

  1. Approved
  2. Declined
  3. Error

Refunds can only be run on 'Approved' transactions that have been settled. 'Declined' transactions cannot be refunded. As a result, in order to test the refund process, you must first pass an odd dollar amount. This will return the transaction with an 'Approved' status. Then, you can test a refund for the transaction.

An error could result from a variety of conditions such as missing data, invalid card numbers, and expiration dates provided in invalid formats.

The following sample code calls a routine from our Code Library.

* BluePay C#.NET Sample code.
* This code sample runs a $3.00 Credit Card Sale transaction
* against a customer using test payment information. If
* approved, a 2nd transaction is run to refund the customer
* for $1.75.
* If using TEST mode, odd dollar amounts will return
* an approval and even dollar amounts will return a decline.
