# Delete a tag assignment
Remove a tag assignment from an asset. This action is permanent and cannot be undone. Removing an assignment only detaches the tag from the specified asset; the tag itself is not deleted. Only the tag's creator or an organization admin can delete an assignment for a `private` tag. Assignments for `shared` tags can be deleted by any organization member.
This endpoint does not cost any credits to execute.
