A License Key is a unique identifier generated by Whop for each user who has made a purchase. It acts like a special access code that users can input to gain access to your application.

​

When to use license keys

License Keys are useful when you want to sell & restrict access to desktop applications. For example, if you’re selling a game, you can use license keys to restrict access to users who have purchased the game.

​

Creating a License Key

If you haven’t already created your company or made a product to sell, you’ll want to start there.

Once you’ve done that, head to the dashboard to add the license key experience to your product.

​

Metadata

Metadata is a way to store information about a license key. The most common use case for this is to store information about the user’s device, HWID. Hardware ID is a unique identifier for a device, and can be used to prevent users from sharing their license keys with others.
