External URL in Push Notification

Hello all,

May I ask you how can I include an external URL inside a push notification?

Has to be done through an application variable?
I can use "uri" variable both for deeplink (internal mobile page) and external URL or I have to use 2 application variables?

Thanks in advance,
Salvatore
