Automatic Subscription Renewal

The Oxygen License Server has a mechanism that tries to detect when you purchase a renewal of your current subscription and automatically updates the license key.

To determine that a license key you purchased is a renewal of the license key you have currently installed in the License Server, it uses the Previous order reference number if you inserted it in the checkout process.

This automatic renewal mechanism makes an HTTP request to https://oxygenxml.com/subscription_management/check_renewal.php and passes the following as parameters:

• The SGN field of the existing license key.
• The server signature that uniquely identifies the License Server installation.

This request is made by the License Server automatically (or manually by pressing the Check now link).

This mechanism can be disabled by deselecting the Automatically check for subscription renewal checkbox.
