Issue Summary

The Confluence Cloud attachment APIs (both v1 and v2) continue returning downloadLink URLs that no longer work and instead return HTTP Status 401 – Unauthorized.

Affected APIs:

• v1: /wiki/rest/api/content/<page-id>/child/attachment
• v2: /wiki/api/v2/pages/<page-id>/attachments

The returned download links are in the following format:

https://<site>.atlassian.net/wiki/download/attachments/<page-id>/<attachment-name>?api=v2

This behavior appears related to the deprecation/change announced in CHANGE-3007, however the APIs still return these non-functional links in the response payload, which is causing confusion for customers and breaking integrations.

Steps to Reproduce

1. Step 1: Call either the v1 or v2 attachment API.
2. Step 2: Copy the downloadLink returned in the response.
3. Step 3: Open the link using authenticated access.

Expected Results

The API should return a valid downloadable URL or stop returning deprecated/non-functional links.

Actual Results

The returned download URL fails with:

HTTP Status 401 – Unauthorized 

Workaround

The following endpoint should be used as mentioned in CHANGE-3007:

GET /wiki/rest/api/content/{id}/child/attachment/{attachmentId}/download
