hi Team, 

We are doing a POC where we are hitting a global pay page from Pega and from this global pay page, after the card detail are saved, a call is made to external system , and on return of the response , if it is a success, the thankyou page has to be shown. the requirement is to show the thankyou page and this page should come from PEGA. So, in Pega can we create a page and provide a URL to the external system on hitting of which the page should be displayed?
