How to verify particular API call

I have a scenario where I need to validate a particular string in one Request URL (Not Response validation). Can anyone help me?
Ex:
Request URL:
https://www.google.com/gen_204?s=webhp&t=aft&atyp=csi&ei=pNoNY5Vq6IqvvA-J0qDoBQ&rt=wsrt.217,aft.241,afti.241&wh=873&imn=2&ima=1&imad=0&aftp=-1&r=1&bl=b1zC

I want to validate if this request URL appears with the below string “s=webhp”

I can’t use the status code with 200 as irrespective of the string I am getting 200 status.

Have you tried to use Get Current Url with validation, like in this image?
