Make Recurring Income by Selling API Keys for Products and Services with the WooCommerce API Manager. The WooCommerce API Manager can turn most WooCommerce Product types into an API Resource that can be accessed with an API Key. API Resources (products) could be software, a service, an iPhone or Android App, a membership, a subscription, or anything that can be accessed over the Internet. How does it work? The customer buys one or more API Key activations that can used for an API Resource, then uses the API Key to access the API Resource, which is the product or service, and the WooCommerce API Manager controls access to the API Resource for the length of time set for that API Resource. For even more advanced API Resource time management, the WooCommerce API Manager works seamlessly with WooCommerce Subscriptions.
