The templates API provides full CRUD access to CMS templates in the design manager, along with buffer management for draft edits and version history for restoring previous states.
This is a legacy v2 API, which does not have a newer version available. It’s recommended to use one of these modern alternatives instead:
  • Local development: use the HubSpot CLI (hs fetch and hs upload) to manage template files directly from your local file system.
  • Programmatic access: use the CMS Source Code API to read and write template files via API.
