  title: Lemmy REST Account Private Messages API
  description: The Lemmy REST API provides programmatic access to all core platform features of Lemmy, a free, open-source, self-hostable federated link aggregator and discussion platform. Developers can create and manage posts, comments, communities, and user accounts; vote on content; follow communities; search across the federated network; moderate communities; send private messages; and administer instances. Authentication uses JWT bearer tokens obtained via the login endpoint. The API is versioned at /api/v4/ and available on any public Lemmy instance.
