Use this endpoint to generate a short audio clip from a text prompt through Kling.

​
Before you call it

  • Keep prompt concise and direct
  • Start with duration between 3 and 10 seconds
  • Treat callback_url and external_task_id as optional integration helpers, not core requirements

​

Submit the audio task

Send the text prompt and duration, then save the returned task id.
2

Poll the task

Continue with Individual Queries using the Kling audio query path until the task reaches a terminal state.
