  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.

    description: >-
      The Clio Manage API v4 is a JSON REST API that gives developers programmatic access to Clio's legal practice
      management data model — matters, contacts, activities, bills, trust accounts, documents, tasks, calendar entries,
      custom fields, and users. Authentication is OAuth 2.0 (authorization code flow). Regional endpoints exist for the
      U.S. (app.clio.com), Canada (ca.app.clio.com), EU/UK (eu.app.clio.com), and Australia (au.app.clio.com). Standard
      pagination, filtering, sparse fieldsets, and ETag-based caching are supported.
