Use this endpoint to preview the selected region before you submit the final multimodal edit task.

​
Why preview matters

  • It lets you verify that the selection points cover the intended object or area
  • It helps catch bad masks before you spend a generation call
  • It is the safest checkpoint between selection editing and final task creation

​
Workflow role

Initialize the session

2

Add selection points

3

Preview before generating

Call this endpoint, then continue to Create Task only after the selection looks right.
For the complete parameter reference, see the Kling API documentation.
