Dear Burak Uyanik,
You need to use HTTP services in 1C. Just construct the string of GET or POST requests according to Google API docs and send request. In response you will get JSON or XML answer from Google which you need to parse.
Below is small example
JSONString = "";
ServerAdress = "localhost";
Resource = "/api/1.0/sync/product/";
HTTP = New HTTPConnection(ServerAdress,,);
HTTPRequest = New HTTPRequest(Resource);
HTTPRequest.SetBodyFromString(JSONString,TextEncoding.UTF8,ByteOrderMarkUsage.DontUse);
Answer = HTTP.Post(HTTPRequest);
Result = Answer.GetBodyAsString("UTF-8");
