# Midjourney V7 高级编辑

> - 上传图像后在画布上进行高级编辑，支持蒙版区域指定和位置调整
- 与 mj-v7-edit 类似，但不依赖已有任务，直接传入图片
- 异步处理模式，使用返回的任务ID [进行查询](/cn/api-manual/task-management/get-task-detail)

<Note>
  Midjourney 内置内容审核机制。如果生成的部分图像触发了审核过滤，该次请求已消耗的积分将无法退还，请留意提示词的内容合规性。

            - 在计费确认完成后发送

            - 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
