Key facts
- HubSpot's new developer platform is built and managed via "projects" using a file-based build-and-deploy framework containing an app's configuration, assets, and source code.
- Developer platform apps (v2025.2 and v2026.03) are created and deployed via the HubSpot CLI (
hs), e.g.hs project create,hs get-started. - Legacy private apps and public apps remain fully supported and actively maintained.
- All REST APIs are queryable via a private app access token or public app OAuth token.
- If you only need an access token for a few HubSpot APIs, a legacy private app may be preferable to the CLI-driven project workflow.
- Apps can add features such as app cards and webhooks; available features depend on the app's distribution and authentication configuration.
- Quickstart uses
hs get-started; full app setup useshs project create. - Doc index available at https://developers.hubspot.com/docs/llms.txt
