# GET /getPresentationVersion/{presentationId}/{version}

> Owner-only. Return the manifest (list of files + hashes + content types) for a specific version of a presentation.

<Note>
  Owner-only. This endpoint lets the owner inspect a past version's contents (every file, every hash). Recipients cannot fetch arbitrary versions — they only see what their token's `versionMode` resolves to.
</Note>

`path` is the literal path within the deck (preserving the author's folder structure). `sha256` is the content-addressed key for the blob store.

## What this does NOT do

* It does NOT render the version. There's no public URL for "view v2 of this deck" — that would break pinning. The owner can reconstruct v2 locally by downloading each blob (using the sha256 keys) via the dashboard's history view.

## Next

* **[GET /listPresentationVersions](/api-reference/list-presentation-versions)** — discover what versions exist.
* **[Versioning](/concepts/versioning)** — why history is owner-only.
