Kling 自定义主体
- Kling Custom Element (kling-custom-element) 通过参考图片或视频创建可复用的主体元素（角色/物体）
- 创建成功后，返回的
element_id可在 Kling O3 系列和 Kling V3 图生视频中通过element_list参数引用，实现角色外观一致性控制 - 异步处理模式，使用返回的任务ID 进行查询
- 任务完成后，
result_data将包含用于视频生成的element_id
重要说明：
- 本模型用于创建可复用主体（元素），不生成视频，无需 prompt / duration / quality / aspect_ratio 等参数

"kling-custom-element"
模型参数

任务完成后的HTTPS回调地址
回调时机：
- 任务完成（completed）、失败（failed）或取消（cancelled）时触发
- 在计费确认完成后发送
安全限制：
- 仅支持HTTPS协议
- 禁止回调到内网IP地址（127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x等）
- URL长度不超过
2048字符
回调机制：
- 超时时间：
10秒 - 失败后最多重试
3次（会分别在失败的1秒/2秒/4秒后进行重试） - 回调响应体格式与任务查询接口返回的格式一致
- 回调地址若返回2xx状态码视为成功，其他状态码会触发重试
示例:
"https://your-domain.com/webhooks/video-task-completed"
