Software Licensing for Easy Digital Downloads provides a complete license key generation, activation, and checking system. It allows you to provide license keys along with your digital products that can then be used to properly license and activate the buyer’s copy of the software. Whether you are selling WordPress plugins, themes, or any other kind of software, including video games and desktop applications, the Software Licensing add-on will become a huge asset for you that also helps to take your business to the next level.
With a complete API that can be used for activating, checking, and validating license keys, this is the perfect addition to any digital store selling software, whether that software is WordPress plugins or themes, video games, applications, or any other kind of software.
For WordPress and Non-WordPress Products
The add-on has been built specifically with WordPress theme and plugin developers in mind, but can be used for any kind of software licensing through the included API. Included with the add-on are complete samples that illustrate how to implement license activation and checking in your theme or plugin, and how to setup automatic upgrades for your theme or plugin that are delivered through the licensing system.
