# Policy Comments APIs (aka Complex Iterative Workflows)

These APIs enable collaborative document review within Guardian policies. Users can create discussion threads on policy documents, post messages, attach encrypted files, and inspect document relationships and schemas — all scoped to a specific policy and document.

**Authentication:** All endpoints require a Bearer token (`Authorization: Bearer <token>`). Obtain a token via `POST /api/v1/accounts/login`.
