Level 2 & Level 3 Processing

This code steps you through an example of passing Level 2 & Level 3 data with a transaction.

There are three outcomes when processing credit card transactions:

  1. Approved
  2. Declined
  3. Error

'Approved' transactions can be charged against customers' credit cards. 'Declined' transactions can't be charged. As a result, in order to test the process of charging a customer's credit card, you must first pass an odd dollar amount. This returns the transaction with an 'Approved' status. You can then charge the credit card to complete 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 using TEST mode, odd dollar amounts will return
* an approval and even dollar amounts will return a decline.
