AssureBuy Payment Gateway

The AssureBuy Payment Gateway is a secure, reliable, and easy to implement real-time transaction processing interface that connects web sites, call center applications, accounting systems and other applications to the appropriate payment processing network using any standard SSL encrypted Internet connection. A payment gateway provides the flexibility and scalability necessary to grow with your business while keeping you in control of the primary interface with your customer. The AssureBuy Payment Gateway is easy to install for small businesses, yet robust enough to accommodate the demands of integrated high volume processing applications and e-commerce web sites. For more information on how a payment gateway eliminates the costly investment in software, connectivity, and human resources required by in-house payment processing systems, download our FREE White Paper: Payment Gateways: The Benefits of Outsourcing. The AssureBuy Payment Gateway gives your business the ability to process credit cards, debit cards, purchasing cards, electronic checks, and ACH transactions in real-time through a common TCP/IP interface. A Windows based COM object is also available for easy integration with most common shopping carts and e-commerce applications.


The AssureBuy Payment Gateway is a service that operates remotely on dedicated servers in a secure AssureBuy Data Center. There is no software that needs to be installed, configured or maintained at your business location. Here is a brief summary of how it works:

System Requirements

  • You will need to obtain a credit card merchant account capable of processing the types of transactions appropriate for your business. Learn More about merchant accounts by reading our FREE White Paper: Merchant Account Basics or Contact Us and we can set up a merchant account online.
  • You will need to obtain the expertise, either internally or from a third-party such as your web developer, necessary to integrate your web site or application to the AssureBuy Payment Gateway. View the list of our Web Developer Partners if you need help. If you are looking for an inexpensive e-Commerce solution that requires little or no integration work, see our IntegriCharge® service.
  • Your web server or application must have access to a standard TCP/IP Internet connection.

Setup and Integration


  • Test your payment gateway integration using the AssureBuy test environment.
  • Your dedicated AssureBuy account manager will configure the AssureBuy Payment Gateway to work with your specific merchant services provider and test the connection to verify that transactions are being processed correctly.
  • Perform a live transaction on each payment type you will be using and verify that the funds are deposited correctly into your business account.

Processing Your Payments

  • Your customer makes a purchase on your web site or a customer service representative enters the customer payment information into your processing application.
  • The payment information is encrypted and sent to the AssureBuy Payment Gateway for processing. The payment gateway checks the transaction for fraud, determines which processing network is required to authorize the transaction and routes the information accordingly. The response from the processing networks is re-encoded and returned to the requesting web server or application at your business. The whole process typically takes 3 seconds or less.
  • Your web site or application processes the response and handles the result appropriately. The gateway can be optionally configured to send an e-mail response directly to the customer.
  • Periodically, usually once per day, the AssureBuy Payment Gateway will forward all of the approved payment transactions to the appropriate network for settlement. The funds will usually show up in your business account within 48 to 72 hours, depending on the terms of your merchant processing agreement.

Reviewing the Transactions

  • All transaction information is available in real-time by accessing the AssureBuy Web-Based Administration System. Using this interface, designated users from your business can review payment transactions, review settlements, perform searches, and download payment information for import or analysis.

In Case of Trouble

  • AssureBuy provides a robust set of support tools and employs a highly trained staff of payment processing experts available to assist you by e-mail or telephone. See our Support Center for additional information.
