# Data Hub

## Docs

- [Data API Authentication](https://docs.communityhub.cloud/api-reference/authentication.md): The Data Hub Data API authenticates via Auth0-issued, user-scoped personal access tokens — not API keys with configurable scopes or client-credential exchange.

- [Data Ingestion: Not Part of the Data Hub API](https://docs.communityhub.cloud/api-reference/ingest/overview.md): 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.
