  title: Lemon Squeezy Checkouts Orders API
  description: The Lemon Squeezy API is a REST API based on the JSON:API specification. It exposes the resources of a Lemon Squeezy merchant-of-record account - stores, products, variants, prices, files, orders, order items, customers, subscriptions, subscription invoices, subscription items, usage records, license keys, license key instances, checkouts, discounts, discount redemptions, and webhooks. All requests use Bearer API key authentication and must send the Accept and Content-Type headers application/vnd.api+json.
