# Headless Cloud Drive Indexing

* **[Google Drive indexing](/guides/google-drive-headless)**: index a single file, a folder (recursively), or a user's entire Drive with no per-user OAuth. Your Workspace admin authorizes one service account once; native Docs/Sheets/Slides export automatically. Shared Drives included.
* **[SharePoint indexing](/guides/sharepoint-indexing)**: index a site's document library, a folder, or a single file via an Entra ID app your admin consents once. Supports least-privilege `Sites.Selected` so Captain can read one site and nothing else.
* **[OneDrive indexing](/guides/onedrive-indexing)**: index any user's OneDrive for Business by email, same app-only auth.
* **[Backblaze B2 indexing](/guides/backblaze-indexing)**: bucket, directory, and single-file endpoints with a read-only application key.
