  title: Coordinate REST Comments Groups API
  version: v1
  description: 'The Coordinate REST API lets you add, update, and retrieve the entities that make up Coordinate''s client project-execution platform: projects, project pages, tasks, task groups, stakeholders, goals, progress reports, discussion entries (comments), and organizations. All requests are scoped to the vendor that owns the API key; `vendor_id` is derived from the key and cannot be overridden. A companion webhook API lets external systems subscribe to create/update events. This description is captured by the API Evangelist enrichment pipeline from Coordinate''s published agent-oriented API reference.'
