Answer 1

make one pojo class for your sending json data. you can genarate pojo class based on robopojo pulgins or refer this site http://www.jsonschema2pojo.org/

after date define this method for api calling..

    @POST("url")
Call<ResponseData> getData(@Body User user);

and also server response pojo class

You are passing data in wrong way change this way your error message display you need to pass data in multipart and you are passing in JSON
