# Void an e-signature request

`https://www.helprange.com/api/v2/signature-requests/{envelope_id}/void`

Cancels a sent request: nobody can sign it any more and the waiting recipients are told. Cannot be undone.

**Plans:** Pro, Max, Unlimited, Deal Room Pass, trial. **Auth:** `Authorization: Bearer hr_live_…` (team key), `X-API-Key`, `Authorization: Api-Key <key>` or an OAuth `Bearer` token. **Scope:** `documents:write`. **Operation id:** `voidSignatureRequest`

## Parameters

| Name | In | Type | Description |
|---|---|---|---|
| `envelope_id` required | path | string | E-signature request id (from List e-signature requests). |

**Header** `Idempotency-Key` (optional, up to 255 characters): retry with the same key and body within 24 hours and you get the first response back (`Idempotent-Replayed: true`) – the request is not run twice. Another body: `422 idempotency_key_reused`; still running: `409 idempotency_key_in_progress`. [More](https://www.helprange.com/developers/api#idempotency).

## Request body

Content types: `application/json`, `application/x-www-form-urlencoded`.

| Field | Type | Description |
|---|---|---|
| `reason` | string | Optional, shown to the waiting recipients. |

## Example request

```
curl -X POST https://www.helprange.com/api/v2/signature-requests/9f1c2e7a4b/void \
  -H "X-API-Key: $HELPRANGE_API_KEY" \
  -H 'Content-Type: application/json' \
  --data-binary '{"reason": "Wrong version"}'
```

```
const res = await fetch('https://www.helprange.com/api/v2/signature-requests/9f1c2e7a4b/void', {
  method: 'POST',
  headers: {'X-API-Key': process.env.HELPRANGE_API_KEY, 'Content-Type': 'application/json'},
  body: JSON.stringify({
    "reason": "Wrong version"
  }),
});
const data = await res.json();
if (!res.ok) throw new Error(`${res.status}: ${data.error || data.message || data.reason}`);
console.log(data);
```

```
import os

import requests

r = requests.post(
    'https://www.helprange.com/api/v2/signature-requests/9f1c2e7a4b/void',
    headers={'X-API-Key': os.environ['HELPRANGE_API_KEY']},
    json={
        "reason": "Wrong version",
    },
    timeout=60,
)
r.raise_for_status()
print(r.json())
```

The samples read the key from the `HELPRANGE_API_KEY` environment variable.

## Responses

| Status | Description |
|---|---|
| `200` | OK |
| `400` | Invalid input – the message says which parameter. |
| `401` | Missing or invalid API key / OAuth token. Team keys: code invalid_key, key_revoked, key_expired or key_owner_removed. |
| `402` | Your plan does not include the REST API (the Free plan) or this feature (e.g. NDA needs Max). |
| `403` | The team API key lacks the scope this endpoint needs. |
| `404` | Not found – or not yours (the API never says which). |
| `405` | Wrong HTTP method for this endpoint. |
| `409` | The data room is frozen, the signed PDF is not ready yet, (webhooks) the team already has an endpoint / the endpoint is turned off, or (code idempotency_key_in_progress) a request with the same Idempotency-Key is still running – retry in a few seconds. |
| `422` | code idempotency_key_reused: this Idempotency-Key was already used in the last 24 hours with a different request (method, path or body). Use a new key for a new request. |
| `429` | A usage limit was reached – wait Retry-After seconds. |

## Try it

**Uses your real account.** The request goes from your browser straight to `www.helprange.com` with your API key and acts as you – this POST **changes data**. The key stays in this page (in this tab's session storage only if you tick the box), is never put in a URL and is not sent to analytics. Do not paste a key on a shared computer.
 API key

  Remember in this tab

envelope_id (path, required)  JSON body { "reason": "Wrong version" }
