I want to write Http post by passing the url like this https://aspi.whatsapp.com/send?phone=9199458224XX&text=Hello%20GujaratBy post method end-user will receive whatsapp message I think.
Now you talking about screen scraping.
your webclient does the same get. The response will be the html you see. Presumably the page has a form. You will post back the form values. You probably will need authentication ,and and include the cookie with the form post.
any the easiest way to reverse engineer, is to use fiddler to trace the network requests. Determine how the gets work, and what the form posts are. Then you can duplicate.

To send a WhatsApp message, you need to use the business api
https://developers.facebook.com/docs/whatsapp/getting-started/
The only option available without an account, is the click to open chat page
https://faq.whatsapp.com/general/chats/how-to-use-click-to-chat/
this is a link you put on your page, that navigates to the WhatsApp site.
