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

Task flow

1. 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.

3. Store the audio output

   Persist the final audio asset if you need it beyond the provider delivery window.

Live validation on 2026-03-13 confirmed that a minimal request with only prompt and duration was accepted and returned task_status: submitted.

For the complete parameter reference, see the official Kling documentation.
