Request Headers 
Authorization: Bearer {API token}
Query Parameters

  • voiceId is required, the numeric id of a saved voice from GET /videos/voices.

  • email is optional when only one account configured.
    However, if you have multiple accounts configured, this parameter becomes required.
    Use the account that saved the voice.

Responses

  • 200 OK

    {
  "deleted": true
}

  • 400 Bad Request

    The voiceId is not a numeric voice id.

    {
  "error": "Parameter voiceId (my-voice) has incorrect format"
}

  • 401 Unauthorized

    {
  "error": "Unauthorized",
  "code": 401
}

  • 404 Not Found

    Kling did not delete the voice, for example because it is not a voice saved to this account.

    {
  "error": "Voice 301234567890 was not deleted"
}
Model 
{ // TypeScript, all fields are optional
  deleted: boolean
