  title: Quix Cloud HTTP APIs Definitions Topics API
  description: 'OpenAPI 3.0 description of the HTTP (REST) surfaces of Quix Cloud: the Streaming Writer API for publishing time-series parameter data, events, and definitions into Quix topics, and the account-wide Portal API for managing workspaces, topics, and deployments.


    The Streaming Reader API is delivered exclusively over a Microsoft SignalR hub (WebSockets / Long Polling) and is therefore modeled separately in the companion AsyncAPI document at asyncapi/quix-asyncapi.yml, not here.


    All endpoints authenticate with a Quix Personal Access Token (PAT) supplied as an `Authorization: Bearer <PAT>` header. The Streaming Writer API base host is environment-specific (`writer-{environmentId}.cloud.quix.io`); the Portal API is account-wide (`portal-api.platform.quix.io`). Endpoint paths are documented by Quix; per-environment Swagger/OpenAPI references are available from the Quix portal under Settings > APIs and tokens.'
