follow these steps:
1.) firstly create modal class (myrequestclass) post request http://www.jsonschema2pojo.org/
2.) create modal (myresponseclass) server response same site.
3.) set values want send server creating object of myrequestclass.
4.) hit api using method in interface:
@post("/provider/filter") call<myresponseclass> senddatatoserver(@body myrequestclass mymodal);
