# DELETE /emails/scheduled/{id}

Part of the SendHeron REST API. Base URL: `https://api.sendheron.com/api/v1`

Cancel an email scheduled with `sendAt`, before it fires.

```http
DELETE https://api.sendheron.com/api/v1/emails/scheduled/{id}
Authorization: Bearer <YOUR_API_KEY>
```

**Required scopes:** `emails:send`

**Success status:** `200`

**Rate limit:** 100/min per key, counted against the organization's WRITE ceiling (400/min).

**Path parameters**

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | uuid | yes | The scheduled email's UUID, returned by the send that scheduled it. |

> Only works while the send is still pending. Once it has dispatched, mail cannot be recalled, so an already-sent id returns a 400 rather than falsely reporting success.

Rate limits: 100/min per key, counted against the organization's WRITE ceiling (400/min). Both windows are one minute; there is no hourly or daily quota.
