Robust Connection Methods:

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.

Simple Integration Method (SIM) is  the easiest and most practical integration method. Merchants and developers with Web expertise and resources who are able to perform their own integration can use the time-saving resources such as sample code, and  SIM, API documentation.

Advanced Integration Method (AIM): 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.
