# Cancel a queued segment action
> Cancel your pending segment action. An action already running cannot be cancelled.
Cancel your pending segment action. An action already running cannot be cancelled.
```http theme={null}
POST https://api.voicecheap.ai/v1/actions/segment_actions_cancel
```
## Authentication and permissions
Send a VoiceCheap API key in this header. Authorization: Bearer with the same API key is also supported. OAuth access tokens are accepted only by
MCP, not by this REST endpoint.
Required permissions: `translations:write`.
An active paid subscription is required. Permissions do not change team roles, resource ownership, media credits, or plan limits.
## Parameters
Text value.
Minimum length: 1. Maximum length: 200. Pattern: `^[^/\\]+$`.
Text value.
Format: "uuid". Pattern: `^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$`.
Optional at the transport boundary: the server injects an identifier before validation when omitted. Supply your own stable UUID v4 to recover safely from a lost response.
Format: "uuid". Pattern: `^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$`.
The JSON Schema below preserves the exact field names, nested types, defaults, bounds, and accepted values exposed by discovery. Additional cross-field rules are listed in the operation notes.

"description": "UUID v4 for this action. Reuse the same ID with identical arguments on retries."
}
},
"required": ["projectId", "jobId"],
"additionalProperties": false
}
```
## Idempotency
Use a UUID v4 in requestId or the Idempotency-Key HTTP header for each mutation. Reuse the same identifier and identical arguments after a network failure. If both are supplied, they must match. Replaying a saved request does not repeat the operation or charge another monthly call. Failed or interrupted requests are not restarted automatically.
Every mutation can return HTTP 202 when a retry finds the same request still running, even when its first execution is normally synchronous. If execution completed but resultStored is false, a retry returns HTTP 200 with saved request state instead of the original result. Retrieve the output through its domain history, result, or download action.
## Request examples
Replace example resource identifiers and media keys with values returned for your account. Keep the request identifier stable when retrying the same mutation.

## Response
A successful first execution returns HTTP 200 with the operation result under data. A replay may return saved request state instead. The example shows one supported response, not every optional field.
Returns the full updated queue snapshot after cancelling a still-queued action.

## Result fields
| Field | Description |
| - | - |
| `data.projectId` | Parent project identifier. |
| `data.revision` | Queue snapshot revision. This is independent of projects\_get.segmentStructureRevision. |
| `data.items` | Project action progress: job identifiers, action metadata, state, timestamps and optional public errorCode. |
| `data.items[].id` | Job identifier; equals the original queue submission requestId. |
| `data.items[].action` | Action metadata only: type, segmentIndex, and optional workId, translatedVersionId and source. Submitted text, timing values and regeneration instructions are not returned. |
| `data.items[].status` | queued, running, completed, failed, or cancelled. |
| `data.items[].createdAt` | Queue item creation time in Unix milliseconds. |
| `data.items[].startedAt` | Optional first start time in Unix milliseconds. |
| `data.items[].finishedAt` | Optional terminal time in Unix milliseconds. |
| `data.items[].errorCode` | Optional public failure code. Unclassified failures use ACTION\_FAILED. |
| `data.items[].seenAt` | Optional acknowledgement time for the authenticated viewer only. |
## Recover and poll this request
Use the same identifier even after a lost connection. If resultStored is false, retrieve the output through the corresponding history, result, or download action. Never start a second generation merely to check progress.

## Operation notes
* jobId identifies the queue item to cancel; requestId is a separate stable UUID v4 for the cancellation request.
* Only a queued item can become cancelled. Running, completed and failed items cannot be cancelled. Cancelling an already-cancelled item returns the current snapshot.
* The handler returns projectId, revision and items directly; there is no success boolean or nested queue field.
* A cancellation does not refund completed generation or stop media work already running.
* Queue responses, including submission, cancellation, polling and replay, contain action metadata only. Read transcript content with transcripts\_get and the required transcription:read permission.
## Usage
Each successful invocation consumes one monthly API/MCP call. Media credits and the operation's own generation allowances also apply.
