how can I define the input parameter in the detail page when I used external URL ?

I'm working on page that I can write the page that I want to navigate to it dynamically. 

I used external site URL to navigate and wrote that URL
That works, but now when I navigate to detail screen for example it gave me an empty form.
My question is, how can I define the input parameter in any detail page that wrote dynamically as Entry point and I want to navigate to it. :)
