# POST /deletePresentation

> HARD DELETE a presentation. Removes every version, asset, collaborator row, and the Firestore doc. Irreversible.

<Warning>
  This operation is **irreversible**. Once removed, the deck, every version, every asset, and every collaborator row are gone for good.
</Warning>

## When to use

You want to permanently remove a presentation. For non-destructive alternatives, see [`unsharePresentation`](/api-reference/unshare-presentation) and [`uninviteCollaborator`](/api-reference/uninvite-collaborator).

## Endpoint

```
POST https://europe-west1-slideless-ai.cloudfunctions.net/deletePresentation
```

## Authentication

`Authorization: Bearer <key>` — owner only.

## Request body

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{ "presentationId": "01HXYZ..." }
```

## Response

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "success": true,
  "data": { "success": true, "blobsDeleted": 47 }
}
```

`blobsDeleted` is the number of GCS objects removed (manifests + content-addressed blobs) — a sanity check you got the full prefix.
