# Midjourney V7 Remix

> - Re-create previously generated images with new prompts
- Change content or style while preserving the original image structure
- Difference from variation: remix requires a prompt to reinterpret the original
- Async processing mode, use the returned task ID to [query status](/en/api-manual/task-management/get-task-detail)

<Note>
  Midjourney has a built-in content moderation system. If some generated images are filtered by moderation, credits consumed for that request will not be refunded. Please ensure your prompts comply with content guidelines.

            HTTPS callback URL for task completion


            **Callback timing:**

            - Triggered when task is completed, failed, or cancelled

            - Sent after billing confirmation


            **Security restrictions:**

            - HTTPS protocol only

            - Callbacks to private IP addresses are prohibited (127.0.0.1,
            10.x.x.x, 172.16-31.x.x, 192.168.x.x, etc.)

            - URL length must not exceed `2048` characters


            **Callback mechanism:**

            - Timeout: `10` seconds

            - Up to `3` retries after failure (retries at `1`s/`2`s/`4`s after
            failure)

            - Callback response body format matches the task query endpoint

            - A 2xx status code is considered successful; other status codes
            trigger retries
