We're using your WebTab feature to embed our application, vWorkApp, in Zoho CRM. 

This is working well except we need a way to pass through something that uniquely identifies who the Zoho user is. Is it possible for the WebTabs to append parameter to the link URL, such as the logged in user's ID? 

For example something like the following would be perfect:

- The user creates a web tab that links to: http://go.vworkapp.com?user_id=$zoho_userid

- When the user clicks the tab the URL is called, except the $zoho_userid part is replaced with the user's ID.

Kind regards,
