Request body

webhook_urlstring uri

Optional callback URL that receives asynchronous notifications when the task changes status. The payload includes the task status and result URL when completed.

promptstring

Text prompt describing the desired video content. Maximum 2500 characters. Required for text-to-video mode or when not using multi_prompt.

Tips for better results:

  • Be specific about motion, camera angles, and actions
  • Describe the scene, characters, and atmosphere
  • Reference elements in your prompt as @Element1, @Element2
  • Reference voices with <<<voice_1>>> and <<<voice_2>>>
start_image_urlstring

URL of the image to use as the first frame of the video. Required for image-to-video mode.

Image requirements:

  • Minimum: 300x300 pixels
  • Maximum: 10MB file size
  • Aspect ratio: 1:2.5 to 2.5:1
  • Formats: JPG, JPEG, PNG
end_image_urlstring

URL of the image to use as the final frame of the video. Optional for image-to-video mode.

Image requirements:

  • Same as start_image_url
generate_audioboolean

Whether to generate native audio for the video.

multi_shotboolean

Enable multi-shot mode for multi-scene video generation. When true, use shot_type and multi_prompt to define scenes. When false (default), generates a single continuous video.

shot_type'customize' | 'intelligent'

Controls how multi-shot video generation is segmented:

  • customize: User provides explicit per-shot prompts and durations via the multi_prompt array. Each shot is defined manually.
  • intelligent: Enables automatic scene segmentation by Kling AI. Can be used without multi_prompt (Kling auto-segments the video based on the main prompt) or with multi_prompt (user-defined shots combined with AI segmentation).

Note: This parameter maps to Kling's internal "intelligence" spelling for the intelligent option. Defaults to "customize" when multi_prompt is provided.

aspect_ratio'16:9' | '9:16' | '1:1'

Aspect ratio for the generated video:

  • 16:9: Landscape (widescreen) - ideal for YouTube, presentations
  • 9:16: Portrait (vertical) - ideal for TikTok, Instagram Stories, Reels
  • 1:1: Square - ideal for Instagram posts, social media
duration'3' | '4' | '5' | '6' | '7' | '8' | '9' | '10' | '11' | '12' | '13' | '14' | '15'

Duration of the generated video in seconds.

Range: 3-15 seconds Note: When using multi-shot mode, total duration across all shots cannot exceed 15 seconds.

negative_promptstring

Undesired elements to avoid in the generated video. Maximum 2500 characters.

cfg_scalenumber float

Guidance scale controlling prompt adherence versus creative freedom. Range: 0 to 1. Values above 1 are not supported for Kling 3 (only Kling 1.x models support cfg_scale up to 2).

  • 0: Maximum creative freedom, loosest interpretation of the prompt
  • 0.5 (default): Balanced between prompt adherence and creativity
  • 1: Strongest adherence to the prompt, least creative variation
