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

I have create custom button in deal page passing param and open webview.

 Is it possible for the WebTabs to append parameter to the link URL?

For example something like the following would be perfect:

-web view url  http://test.com

- The user creates a web tab that links to:  http://test.com?dealId=$zoho_dealId

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