Request Body

{
  "email": "[email protected]",
  "workId": -123456,
  "image": "https://s21-kling.klingai.com/.../person.jpg",
  "prompt": "Person dancing energetically",
  "duration": "5",
  "mode": "std",
  "character_id": 0,
  "change_direction": false,
  "sound_effect": true,
  "audio_prompt": "upbeat music",
  "music_prompt": "electronic dance music",
  "enable_asmr": false,
  "replyUrl": "https://your-callback-url.com/webhook",
  "replyRef": "your-reference-id"
}

email is optional when only one account configured. However, if you have multiple accounts configured, this parameter becomes required.
workId is required, integer. Motion identifier from GET /videos/motions.
Negative values indicate official Kling motions, positive values indicate user-uploaded motions.
image is required, URL to the image containing the person. The person’s body and pose should be clearly visible.
Must be uploaded via POST /assets first - use the url field from the response.
prompt is optional, string up to 2500 characters. Text description to guide the video generation.
duration is optional, must be 5 or 10. Duration of the generated video in seconds.
Default: 5
mode is optional, must be std or pro. Generation quality mode. Pro mode provides higher quality but costs more.
Default: std
character_id is optional, integer from 0 to 10. When the image contains multiple people, this selects which character to animate (0-indexed, counting from left to right).
Default: 0 (leftmost person)
change_direction is optional, boolean. When true, mirrors/reverses the motion horizontally.
Default: false
sound_effect is optional, boolean. When true, enables audio generation for the video.
Default: true
audio_prompt is optional, string up to 2500 characters. Description of desired sound effects (only used when sound_effect=true).
music_prompt is optional, string up to 2500 characters. Description of desired background music (only used when sound_effect=true).
enable_asmr is optional, boolean. Enables ASMR-style audio generation (only used when sound_effect=true).
Default: false
maxJobs is optional, range from 1 to 50. Specifies the maximum number of concurrent jobs.
replyUrl is optional, a callback URL to receive generation progress and result. See GET /tasks/task_id for response model.
replyRef is optional, a reference identifier for the callback.

Notes:

The image must contain at least one clearly visible person
If sound_effect=false, the parameters audio_prompt, music_prompt, and enable_asmr cannot be used
The system will automatically detect characters in the image and select based on character_id
Character detection sorts people left-to-right, so character_id=0 is the leftmost person, character_id=1 is second from left, etc.
To delete a user-uploaded motion used in this request, use DELETE /tasks/task_id with the motion’s taskId from GET /videos/motions

500 Internal Server Error

Kling uses a 500 response to indicate moderation and other issues with the input. It may be hard to separate actual 500 errors from moderation errors, so use the error field text and your best judgement to tell them apart, since the message field most often has very generic and perhaps misleading text.
```
{
  "error": "The content you uploaded appears to violate the community guidelines. (CM_EXT.POther)",
  "message": "Service busy (CM_EXT.POther)"
}
```

When successful, the response includes a task ID which can be used to check the status using GET /tasks/task_id.
