}Midjourney V8.2
Midjourney V8.2 Canvas Edit
- Reposition the image of an existing task on the canvas and fill blank areas with AI
- Suitable for adjusting composition, expanding scenes (outpaint), repainting, etc.
- Note: derived tasks based on V8.2 images (variation / remix / edit) are rendered by the V7 engine upstream (documented by the upstream channel); the result may differ slightly in style from the source image. Pricing is unchanged
- Async processing mode, use the returned task ID to query status

}Midjourney has a built-in content moderation system. Each image is moderated individually: filtered images are left out of the results and the remaining images are delivered normally, so you may receive fewer images than usual. If at least one image passes, the task is
completed and billed normally; if all images are filtered, the task ends as failed and the reserved credits are refunded in full. Please make sure your prompts and reference images comply with the content guidelines.Authorizations
All endpoints require Bearer Token authentication

HTTPS callback URL for task completion
Callback timing:
- Triggered when the task is completed or failed
- 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
2048characters
Callback mechanism:
- Timeout:
10seconds - Up to
3retries after failure (retries at1s/2s/4s after failure) - Callback response body format matches the task query endpoint
- A 2xx status code is considered successful; other status codes trigger retries
