请求体
application/json
模型名称
可用选项:
mj-v7 提示词,支持 Midjourney V7 全部原生参数语法(如 --ar 16:9 --s 500)。
图生图: 在 prompt 开头放置图片 URL,支持格式:.png, .gif, .webp, .jpg, .jpeg
图生图规则:
- 单图 + 无文字 = 无效(会报错)
- 单图 + 文字描述 = 有效
- 多图 + 无文字 = 有效
- 多图 + 文字描述 = 有效

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/image-task-completed"
