  title: Payload CMS REST Collections API
  description: Payload is a TypeScript-first headless CMS and application framework that auto-generates REST and GraphQL APIs from collection schemas. The REST API exposes collections at /api/{collection-slug}, globals at /api/globals/{global-slug}, auth operations at /api/{user-collection}/login etc., and user preferences at /api/payload-preferences/{key}. Authentication uses JWT tokens issued by the login endpoint.
