Check If a Customer Has Enough Credit Available

This code steps you through the process of validating a customer's credit card information and authorizing a potential charge against the card.

You can test for both outcomes:
Approved: When you pass odd dollar amounts, payment authorizations are returned with an 'Approved' status.
Declined: When you pass even dollar amounts, payment authorizations are returned with a 'Declined' status.

The 'Approved' payment authorization does not charge the customer's credit card.
For that Go to: Charge a Customer or Run a credit card transaction

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

* BluePay Java Sample code.
* This code sample runs a $3.00 Credit Card Auth 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.
