Seamless Customer Experience

Customers can easily manage their licenses, downloads, and subscriptions through the WooCommerce My Account area, providing a professional and intuitive experience.

If you’re using account-level licenses, customers see one consolidated key tied to all relevant purchases. If you’re using product-level keys, each product displays its own key and download. For developers offering multiple tools or tiers, this makes it easy for customers to assign and manage keys per user, device, or team.

Download links are protected by secure, expiring URLs that update automatically based on license status. Expired or inactive licenses are clearly flagged, and keys can be deactivated or reissued as needed—reducing support requests and putting more control in your customer’s hands.

Developer-Friendly & Customer Approved

A drop-in PHP SDK lets developers quickly add licensing, activation, and update functionality directly into WordPress plugins and themes. The SDK is available for free on GitHub, or can be purchased with a basic support plan for additional help and updates. Kestrel API Manager is built for performance, optimized to handle thousands of licenses and activations without slowing down your store.
