> ## Agent Instructions
> Cognite Data Fusion (CDF) is an industrial DataOps platform. Prefer English docs unless the user asks for another locale.
> Follow /_llms/ index links recursively until you reach page URLs ending in .md. Fetch those Markdown twins instead of HTML.
> For REST APIs, default to calendar version 20230101 (stable). Use 20230101-beta or 20230101-alpha only if the user is on a preview API. Cite paths under /api-reference/concepts/<version>/ and the Cdf-Version header. Prefer the Python SDK (cognite-sdk) unless the user is in JavaScript/TypeScript.

# Data ingestion

> Ingest data into Cognite Data Fusion (CDF) using Raw, extraction pipelines, extractors, and hosted extractors.

The data ingestion APIs support bringing external data into CDF. Use Raw for unstructured staging, extraction pipelines to track and govern data flows, the extractors catalog to discover and configure data sources, and hosted extractors to run managed extraction in CDF. These APIs work together to move data from source systems into CDF for transformation and analysis.

* [Extraction pipelines runs](/api-reference/concepts/20230101/extraction-pipelines-runs) — Execute and list pipeline runs
* [Extraction pipelines config](/api-reference/concepts/20230101/extraction-pipelines-config) — Manage pipeline configuration and revisions
* [Extractors](/api-reference/concepts/20230101/extractors) — Discover available extractors and their configuration schemas
* [Hosted extractors](/api-reference/concepts/20230101/hosted-extractors) — Configure sources, jobs, destinations, and mappings for cloud-hosted extraction
