Tableau Server Safe List / Whitelisting
If you are using Apps for Tableau Extensions on Tableau Server, you need to configure a Safe List (also called a Whitelist) to allow the extensions to work properly. This guide explains how to do that.
Why is Whitelisting Required?
CommentShare feedback on the editorTableau Server has a built-in security setting that blocks extensions unless their URLs are explicitly added to the Safe List.
In the Safe List section, add the extension URLs you want to allow.
Option A: Whitelist the Exact URL
Example: https://tableau-wb.test.us/extension/
Option B: Use Wildcard Whitelisting
To allow all subpaths of a domain, use: https://tableau-wb.test.us/.*
Wildcard whitelisting is recommended to avoid errors due to trailing slashes or subpaths.
Common Error Message Example
The WriteBackExtreme extension (URL: https://tableau-wb.test.us/extension/) is not on the safe list for this site.
This means you need to whitelist this exact URL or use a wildcard.
