How to pass session variable to php file without including app connect

Hello,

How can I pass a session parameter or a parameter from an app connect application to an .php file where there is no app connect framwork included?

I can send query parameter by using ‘?’ at the end of the file path link and than use the $_GET for assign it to a variable.

What I need is that, the parameter should not being seen in the URL of the file at the adrress bar.

How can I pass paramaters to assign varibale in my normal php file without using app connect?

I tried API Action from client side and add query paramaters but is it not working.

Thank you.
