Online activation and validation features of XLS Padlock let you control user access to your Excel workbooks remotely. For instance, you can sell subscriptions for your Excel spreadsheets and block access of customers if their subscription expired for non payment.
To manage subscriptions, we chose FastSpring, an ecommerce partner of choice for selling software online. This FS subscription kit requires an active FastSpring account.
The workbook applications compiled with XLS Padlock can communicate with a web application powered by this subscription kit. The application uses FastSpring API to manage customer settings and subscription data.
The following guide contains instructions to set up the web application on your server and link it to your Excel workbooks. After that, online activation and optionally validation will be functional. You will be able to manage access of your customers directly from the FastSpring Dashboard.
