  Clio is a cloud-based legal practice management platform used by law
  firms for matter management, contacts, calendaring, time and billing,
  trust accounting, document management, tasks, and client communications.
  The Clio Manage API is a REST/JSON API at app.clio.com/api/v4 that uses
  OAuth 2.0 (authorization code flow) for authentication and exposes the
  full data model behind Clio Manage, with regional endpoints for the
  U.S., Canada, EU/UK, and Australia. Webhooks deliver near real-time
  event notifications, and the Clio App Directory hosts certified
  third-party integrations.
