WooCommerce License Keys will add a new product type to your WooCommerce setup allowing you to create and update licensed products.
Select “License Key” from the available product types to create a licensed product.

You can sell physical or virtual licensed products by checking the “Virtual” checkbox next to the type drop-down.
Product Properties
A “License Key” side tab will appear when the “License Key” product type is selected; clicking the side tab will allow you to view the available product options you can modify.

SKU
The SKU (stock-keeping-unit) is commonly known and used as the product identifier when handling stock. It is widely used on online and retail stores as the code or ID to identify a product. The API will use this property to identify a product and will be required regardless if it has no stock to manage.

Expires
Check this option if your license keys will expire.
Expire interval
