For site integration with 2Checkout, we offer a Common Gateway Interface (CGI). This means a site will need to contain an HTML form or link with cgi parameters appended which passes the correct parameters (and the customer) to our site for checkout. Passing in the Proper Parameters will result in the customer going through the rest of our checkout process (such as entering their credit card information), and after verification, a successful sale.

A site/shopping cart can pass orders into our purchase routine by using one of our supported parameter sets listed below.

• Plug n Play parameters
• Pass Through Products parameters
• Third party cart parameters
• Authorize.net parameters

When using a third party cart parameter set you will need to make sure that you implement the Product Identification parameters listed in the articles above.

If you would like to test your integration of these parameter sets, please try using the testing tools available in our developers area.
