WooCommerce Serial Key lets you generate, distribute and validate serial keys for your downloadable products.

If you are selling software, or other downloadable products, this extension lets you manage the complete licensing system easily. When someone purchases your product, a serial key will be issued. A simple API allows integrating serial key validation routines in your software (examples available with the product). If you’ve set an expiry for the product (number of days or downloads), the license key will stop validating once access to the product expires.
