Fill form of other website by autogenerated url

Hi guys…its not a real wappler question, but important for my project.

What i plan to do:
Lets say there is site abc.com, a foreign site, and there is my site xyz.com.
abc.com has a contact form, lets say its abc.com/contact.php and there are some fields. I would like to automatically open the site/form by clicking a button at xyz.com and fill some fields, like name, by clicking a button at my site so users dont have to fill out every single field.

Is this possible? If yes…how?

Thank you very much guys!
