Ajax with Content-Type: application/json

Instead of using parameters in ajax.get is there a way to provide a json object to the url?

In other words I need my call to look like this:
GET http://localhost:56431/api/capacitydata/ HTTP/1.1
User-Agent: Fiddler
Content-Type: application/json
Host: localhost:56431
Content-Length: 49

{“Param1”:“ABC”,“Param2”:“49”}

Not this
as generated using
webix.ajax()
.headers({“Content-type”:“application/json”})
.get(“http://localhost:56431/api/capacitydata/” , JSON.stringify({“Param1”:“ABC”,“Param2”:“49”}), function(text){
//response
});
:
GET http://localhost:56431/api/capacitydata/?{“Param1”:“ABC”,“Param2”:"49"} HTTP/1.1
Accept: /
Content-Type: application/json
Referer: http://localhost:56431/05_series.html
Accept-Language: en-US
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko

Hi, it’s only possible with webix.ajax().post(), not .get() method:

webix.ajax().headers({
   "Content-type":"application/json"
}).post(url, {"Param1":"ABC","Param2":"49"});
