## Authentication

- `x-api-key` header (required) — API Key authentication via header

## Servers

- `https://api.sync.so` (Default, default)
- `https://dev-api.sync.so` (dev)
- `http://localhost:3001` (local)

Voice deleted successfully

- `boolean`

## Errors

### 401 Unauthorized Error

Unauthorized - Invalid or missing authentication

- `message` (GenerationErrorMessage, required) — A message describing the error.
- `statusCode` (double, required) — The type of error that occurred.
- `errorCode` (string, optional) — Stable, machine-readable error code (e.g. project_not_found, voice_not_found, concurrency_limit_reached). Branch your error handling on this, not on the message text. The full catalog of codes with messages and suggested fixes is served unauthenticated at GET /v2/errors.
- `suggestion` (string, optional) — A suggested fix an agent can act on.
- `field` (string, optional) — The request field the error refers to, when the failure is tied to a specific field (e.g. projectId, voiceId, input[].assetId).
- `docsUrl` (string, optional) — Link to the documentation page for the failing operation.
- `requestId` (string, optional) — Present on unexpected 500 responses. Include it when contacting support so the failing request can be located directly.
- `generationId` (string, optional) — Original generation ID when available for an uncertain keyed submission. Poll this ID; do not create another action to bypass IDEMPOTENCY_OUTCOME_UNKNOWN.
- `dialogueEditSection` (DialogueEditRetimeFailureSection, optional) — For dialogue_edit_removal_too_large: the section to change, when it can be identified. Create a new dialogue edit preview before submitting again.

### 404 Not Found Error

Job not found

- `message` (GenerationErrorMessage, required) — A message describing the error.
- `statusCode` (double, required) — The type of error that occurred.
