sending message via GET method

you mean REST, right?

check picture.
i think you must have something like this in your project.

no,
I have one definition of wsdl then I created new test suite then new test case and here is teststep called "Test Request" where I created request. So and these teststep I want to send via GET method if it is possible. I try to create test step "HTTP test request" where I can choose method GET but here I don't know how to add request to this message

Hello,

What do you mean add a request? When you are using GET request's params and values are passed in encoded url, so you just need to specify param names, values and style.
