At Google Checkout, we're constantly striving to improve our usability. That's why we've recently simplified and improved the installation and configuration process for the osCommerce Google Checkout module. osCommerce is a popular open-source e-commerce solution and the module is an open-source project hosted on code.google.com.
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 (shown below) that does this for you. This should ease concerns about lines of PHP getting copied into the wrong place. If you want to learn more about the installation process, you can take a look at our documentation, which contains a step-by-step walkthrough with screenshots showing exactly how it works.
For more details, check out our post on the Checkout blog. We're excited about the improvements to the osCommerce Checkout module. If you're using osCommerce, we invite you to give Checkout a try and share your feedback with us.
