How to get custom Query String Parameters in my Web screen preparation action ?

I'm try with HTTPRequestHandler and not found appropriate action.

I have a input parameter of type text and it not fill on request.
Hi Thiago,

First of all welcome to the Outsystems community.
I'm not sure if I understood your question, but since you receive a on your WebScreen, you can simply create the variables sent in the query string as the input parameters of it..In the receiving process the variables are "auto-binded" (if I can say this sentence..).
Hope this helps..
