If you are using Protocol buffer or Flat buffer and want to get Byte String response for server-: 



```
public class ToStringConverterFactory extends Converter.Factory {
    @Override
    public Converter<ResponseBody, ?> responseBodyConverter(Type type, Annotation[] annotations, Retrofit retrofit) {
        if (String.class.equals(type)) {
            return new Converter<ResponseBody, String>() {
                @Override
                public String convert(ResponseBody value) throws IOException {
                    return value.string();
                }
            };
        }
        return null;
    }


}
```
