callback_url - API Doc-CometAPI

For asynchronous tasks (image generation/video generation), if you actively set the callback_url when creating the task, the server will actively notify you when the status of the task changes, with the following protocol

{
  "task_id": "string", //Task ID, system generated
  "task_status": "string", //Task status, enumerated values: submitted, processing, succeed, failed.
  "task_status_msg": "string", //Task status information, when the task fails to show the reason for failure (e.g., triggering the platform's content risk control, etc.)
  "created_at": 1722769557708, //Task creation time, Unix timestamp, in ms
  "updated_at": 1722769557708, //Task update time, Unix timestamp, in ms
  "task_result":{
  	"images":[ //Results of the Picture Class Task
      {
        "index": int, //Picture numbering, 0-9
        "url": "string" //Generate the URL of the image, e.g. https://h1.inkwai.com/bs2/upload-ylab-stunt/1fa0ac67d8ce6cd55b50d68b967b3a59.png
      }
    ],
    "videos":[ //Results of video-based tasks
  		{
        "id": "string", //Video ID; globally unique
    		"url": "string", //URL of the video
        "duration": "string" //Total video duration in s
      }
  	]
	}
}
