# POST /unsharePresentation

> Revoke one viewer token or every viewer token on a presentation. The deck stays — only the public URLs stop working.

<Note>
  Most users should reach for [`slideless unshare`](/cli/commands#slideless-unshare). This endpoint is the raw HTTP surface it wraps.
</Note>

## When to use

You want to stop serving existing viewer URLs. The deck remains editable; to remove it entirely, use [`deletePresentation`](/api-reference/delete-presentation) instead.

## Endpoint

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

## Authentication

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

## Request body

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "presentationId": "01HXYZ...",
  "tokenId": "01H..."   // optional — omit to revoke every token
}
```

## Response

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "success": true,
  "data": {
    "success": true,
    "tokensRevoked": 3
  }
}
```
