OpenAPI Specification

info:
  title: Hourtick Billing API
  version: 1.0.0
  description: 'The Hourtick REST API. Authenticate with a personal API token: create one in **Settings → API tokens**, then send `Authorization: Bearer ht_…`.


    All timer changes go through **POST /api/v1/commands**, the same endpoint the web and Mac apps use. Commands are idempotent per `commandId` (use a new UUID per action, reuse it to retry safely).


    Every response carries a `Server-Time` header (epoch ms). Errors use RFC 9457 problem details.'
