Google Workspace Updates recently posted about changes to third-party cookie requirements that affect existing Google Drive download URLs embedded in websites and apps.
It isn't clear to me if this means that all embedded Drive download links will no longer work, or, if some would continue to work, such as those whose target document's "view" permissions are set to Anyone with the link:Viewer.
Upcoming changes to third-party cookie requirements in Google Drive
- Google Workspace Updates, 2023-10-16
What's changing
Google Chrome and other browsers have begun phasing out third-party cookies in order to better protect user privacy. Starting January 2, 2024, Drive will start serving downloads without requiring third-party cookies that are embedded on third-party websites. This is separate from downloading files from Drive.
If you have specific workflows in place that rely on Drive's download URLs or use an app which relies on Drive's download URLs, you’ll need to switch to the Drive and Docs publishing flows by January 2, 2024.Who's impacted
Admins, end users and developers
Why it's important
Serving downloads without requiring third-party cookies will work to improve usability, security, and privacy for Drive users.
