# callback on POST /v1_1/{}/{}/upload is deprecated

Cloudinary API deprecated POST /v1_1/{id}/{id}/upload, body parameter callback without giving a shutdown date yet.

The body parameter callback on the POST /v1_1/{id}/{id}/upload endpoint is deprecated without a shutdown date. This parameter previously served as a URL to redirect to after upload completion instead of returning the upload response. When support is fully removed, requests relying on this parameter will fail.

## What to use instead

Read the upload response directly, or pass notification_url to receive the upload result as a webhook.
