# Wan 2.7 Image
> Wan 2.7 Image Generation and Editing Model supports text-to-image, text-to-image, image-to-image , image editing, and multi-image reference generation.
## Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Learn how to query task status and retrieve generation results
For production use, we recommend using the `callback_url` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

Optional. Callback URL for receiving task completion
notifications.
- System will POST task status and results to this URL when
generation completes
- Callback payloads structure is consistent with the `data`
object returned by the task status query
- Your callback endpoint should accept POST requests with
JSON payload containing results
- It returns an HTTP 200 status code upon successful receipt

bbox_list:
type: array
description: >-
Interactive editing bounding box regions.
The length of this list must match the number of input
images in `img_urls`.
For images that do not require editing, pass an empty
array `[]`.
Each bounding box uses the coordinate format:
`[x1, y1, x2, y2]`
Where:
- `x1`, `y1` = top-left corner coordinates
- `x2`, `y2` = bottom-right corner coordinates
- Coordinates use absolute pixel positions based on the
original image.
- The origin `(0,0)` is the top-left corner of the
image.
Restrictions:
- Each image supports a maximum of 2 bounding boxes.
- Each bounding box must contain exactly 4 integer
values.
