Quix Topics & Deployments API

  title: Quix Cloud HTTP APIs
  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.

        to a `streamId` that does not yet exist, removing the need to call this
