# Data Ingestion: Not Part of the Data Hub API

> The Data Hub Data API is read-only. There is no public endpoint for writing or ingesting data — data enters Data Hub through connected data sources instead.

<Warning>
  This page previously described a batch/streaming ingestion API. That doesn't exist — the Data Hub **Data API** (in development) is read-only, scoped to retrieving variables and their time-series data. There is no public write/ingest endpoint.
</Warning>

Data gets into Data Hub exclusively through **data sources** — dataloggers (Obvius, JACE, BuildingOS), a sensor platform (Motion), public APIs (AirNow, OpenWeatherMap, GLOS), or CSV upload. See [Connecting Data Sources](/guides/connecting-sources) for source-specific setup.

If you need to pull data out programmatically, see [API Reference: Introduction](/api-reference/introduction) for the real (in-development) Data API design.
