Using RESTful api in ASP.NET MVC

Greetings i am new with asp.net mvc but i have a background in asp.net webforms and i worked with soap and webservices, here is the question there is an API which is based on RESTful i need to add it to my project and get some of the data based on this API, i didn't know how to start using the service, and by this i mean : how to add the url to project and how to call the methods? should i use httpClient and send parameters using querystring? can you point me to right direction? thank you.
