  title: Papercups Conversations Messages API
  description: REST API for Papercups, the open-source customer-messaging and live-chat platform built on Elixir/Phoenix. Covers the documented conversations, messages, and customers resources plus the authenticated user endpoint. Authentication uses a Bearer API key (available from the Papercups dashboard). The hosted instance is at https://app.papercups.io; self-hosted deployments expose the same paths on their own host. Papercups is in maintenance mode (community-maintained).
