Authorize.Net enables all types of merchants to accept secure and reliable credit card and electronic check payments quickly and easily. We offer flexible application programming interfaces (APIs) with no licensing or developing fees, and have numerous certified third-party options that offer quick and secure integration methods. Choose one of the three processes below to get started.

1) Do It Yourself: Our easy-to-implement Simple Checkout allows customers to purchase single items (in any quantity) using our hosted payment form. Simply enter appropriate item information, and HTML code is created to insert Donate or Buy Now buttons into your Web site.

2) Multiple Integration Methods: Merchants and developers with Web expertise and resources who are able to perform their own integration can find time-saving resources such as sample code, documentation, troubleshooting tools, FAQs, and everything else they need to get started in our Developer Center.

Authorize.Net offers several methods of direct integration to the Gateway:

Advanced Integration Method (AIM)

     AIM uses a direct secure sockets layer (SSL) connection to the Payment Gateway and is Authorize.Net’s recommended connection method.

Server Integration Method (SIM) Implementation

     SIM uses a secure, encrypted HTTPS form POST connection to the Authorize.Net Payment Gateway.

Direct Post Method (DPM)

     DPM  allows developers to fully customize the experience of the entire payment flow, while simplifying PCI compliance.

Card Present (CP)  

     Card-Present 1.0 integration to the Authorize.Net Payment Gateway for RETAIL SWIPED transactions.

3) Select a Pre-Integrated Solution: Choosing a pre-integrated product is often the easiest and most practical integration method. There are several Authorize.Net solutions that enable you to submit transactions right away, as well as hundreds of certified, third-party solutions. Our Certified Solutions meet the highest security and integration requirements, including our preferred Advanced Integration Method (AIM).
