  title: LearnWorlds Courses API
  description: 'The LearnWorlds API (v2) is a REST API for programmatically managing an online school on the LearnWorlds course / LMS platform. It exposes school entities - users, courses, enrollments, subscriptions, payments, course progress, tags, bundles, certificates, and webhooks - over HTTPS. The API is served per-school from https://{school}.learnworlds.com/admin/api/v2 and is authenticated with OAuth2 (client credentials): a bearer access token is obtained from the school''s token endpoint and every request also carries the Lw-Client header identifying the client (school) application. API and Webhook access is a plan-gated feature (Learning Center and High Volume & Corporate plans). Version 1 of the API is deprecated. Exact request/response schemas and the full endpoint catalog live in the official reference at learnworlds.dev; the paths modeled here are grounded in the public documentation, help center, and the official API wrapper, and should be reconciled against the live reference.'
