Basic Transaction Processing

• The code provided for this sample is the minimum information that must be provided to process a basic transaction. This sample follows the POST API Devleloper Intergration Guide Section "Operations/ Methods" Basic - Operation (BT1). Includes samples for:
  
    →   Card Not Present Transactions
    →   Swiped (Classic) Transactions
    →   Swiped (Point-to-Point Encryption using MagneSafe) Transactions

Process returning customer payment with "Card on File" previously stored on gateway

• Greatly reduce the PCI scope of your application while easily processing payments of your recurring customers. Never store a credit card within your application again!
  
  Securely store one or more customer credit cards on our gateway and process them by merely sending us the CUSTOMER_NUMBER you wish to charge.
  
  

Setup Recurring Billing (Subscription Processing)

• Programmatically create customer subscriptions for automatic recurring billing. Charge the same amount or include a trial period to easily create payment plans such as $99 down (first payment) followed by $39 per month.
  

Fault Tolerant Processing

• This sample adds the additional logic necessary to provide fault tolerance to your application. Specifically, the API provides a means to identify and VOID transactions which may have been processed, but due to network errors somewhere between the application and the gateway, the application never received a response from the gateway.
  

Other API Operations

• United Payment Services POST API supports a variety of additional operations which can be integrated into any custom application (web, Windows, Mac). The samples above are building blocks to aid in the understanding of how our POST API works and how to use the most common functions.

Please refer to the POST API Developer Integration Guide for a complete list of all operations and options available. If sample code is needed that is not provided here, please Contact Us and we will be more than happy to work with you to provide any additional code that is needed.
