Authorize.Net SIM is a hosted payment form ideal for handling the secure collection and transmission of customer data. The experience can be tailored to match the look and feel of your event ticketing website so that the customer doesn’t realize they are on a hosted page.

  • Payment gateway hosted payment form employs 128-bit SSL data encryption.

  • Customize the look and feel of the payment gateway hosted payment form and/or receipt page.

Connecting a website to the payment processing networks is exceptionally difficult and typically beyond the expertise and technical resources of most online merchants. Instead, merchants can easily connect to the Authorize.Net Payment Gateway, which provides the complex infrastructure and security necessary to ensure fast, reliable and secure transmission of transaction data. Authorize.Net manages the routing of transactions just like a traditional credit card swipe machine you find in the physical retail world, however, Authorize.Net uses the Internet instead of a phone line. See our credit card processing diagram.

The Authorize.Net Payment Gateway is available 24/7 for processing transactions. We also offer a number of value-adding services to assist merchants in managing their businesses and protecting themselves from fraud. Additionally, the free, Authorize.Net Verified Merchant Seal can be added to a merchant’s website to help build consumer confidence.

Merchants log into a secure website called the Merchant Interface to manage their transactions, configure account settings, view account statements, generate reports and more. Since the payment gateway is a browser-based, hosted solution, there is no software to install or maintain.

If you have a question about the Authorize.Net platform or your payment gateway account, you can find information from a number of different sources.
