# GET /api/v2/drive-documents/{drive_document}

Read a document body

- MCP id: drive-documents.show
- Scope: api:read:project_drive
- Scope: api:read:customer_drive
- Scope: api:read:organization_drive
- Scope: api:read:user_drive
- Permission: project_drive::access
- Rate cost: 1 unit, read bucket.
- Cache-Control: private, no-store

Returns one document body in the detail view: `content` as GitHub-Flavored Markdown, plus `?include=content_html` for the sanitised-HTML projection that also carries the colours, highlights, alignment and @mentions Markdown cannot express.

Read that projection first if you intend to write the document back, because a Markdown round-trip discards all four. This endpoint first collects any edits still pending in a live editing session, so the body and the `ETag` describe what has actually been typed; if the collaboration server is unreachable it serves the last stored body instead of failing. The drive item's own metadata (title, folder, tags, owner, effective access) is not repeated here: read it from `GET /api/v2/drive-items/{drive_item}`, following `drive_item_id`. There is no soft delete on this resource, so neither `trashed` nor `force` is an accepted parameter. The declared permission is `project_drive::access`; the other three drive prefixes apply by the owning item's owner type, and the per-item rule is what actually decides.

## Parameters
- drive_document (integer, path): The DriveDocument's numeric id.
- view (string, optional): Which field set to render.
- X-Request-Id (header, optional): A correlation id of your own. It is recorded in our logs next to the server's request id but never returned: the response header always carries the server's id. A value that does not match the pattern is discarded silently, never rejected.
- If-None-Match (header, optional): The ETag a read is conditional on. A match is answered 304 with no body.

## Response 200
- id (integer, required): Id of the document body, not of the drive item it belongs to. The two are numbered separately.
- drive_item_id (integer, required): The drive item this body belongs to. Set on create and immutable afterwards; read the item itself from `GET /api/v2/drive-items/{drive_item}`.
- content (markdown or null, required, detail only): The document body as GitHub-Flavored Markdown: headings, lists, task lists (`- [ ]`), tables, code fences, links and images all survive. Detail-only: pass `?view=detail` to get it on the collection. Markdown cannot express text colours, highlights, alignment or @mentions, so read `?include=content_html` first if the document may contain them: a read of `content` followed by a PATCH of it discards all four permanently.
- created_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Creation timestamp.
- updated_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Last-write timestamp; use for incremental sync. Typing in the collaborative editor moves this, not the drive item's own `updated_at`.
- links (DriveDocumentLinks, required)
  - self (url, required): The canonical URI of this record.
- content_html (html or null, optional, on request): The same document as sanitised HTML, preserving the text colours, highlights, alignment and @mentions Markdown cannot carry. Mention spans round-trip unchanged; constructing a new one is out of scope for v2.0.
