Google Checkout is now easier to install on the open-source platform osCommerce and supports subscription-based payments after the search company introduced new updates its online payment processing application.

"We've completely reworked the installation process by no longer requiring users to manually copy and paste large swaths of PHP code into their files. Instead, we've created an automated deployment app that does this for you by looking for the appropriate PHP insertion points and adding the code where it's needed," Ed Davisson, a Google software engineer, wrote on the Checkout blog.

The upgrade is designed to ease concerns about lines of PHP code getting copied in the wrong place. Additionally, configuration is now easier, Davisson said, because the most important fields are grouped together for easier access, with the rest having been moved to a detailed control panel.
