How do I serialize my class to send it as urlencoded with refit

Question

Hi there I'm trying to send a POST method with refit, using postman so far I can say it's working, if I send the data with the x-www-form-encoded option, the json I send looks like this

{
  "apt": "APT",
  "apartment": "A103",
  "author": "Someone",
  "is_public": "True",
  "is_complaint": "True",
  "show_name": "True",
  "title": "fhj",
  "details": "vvkko"
}

I constructed my class in visual studio and my model to match it pasting that to json

namespace App.Models
{
    public class ManyComplaints
    {
        public SingleComplaint data { get; set; }
    }
    public class SingleComplaint
    {
        public string apt { get; set; }
        public string apartment { get; set; }
        public string author { get; set; }
        public string is_public { get; set; }
        public string is_complaint { get; set; }
        public string show_name { get; set; }
        public string title { get; set; }
        public string details { get; set; }
    }

}

Here I'm not sure if I did right it's my api caller

 [Headers("Content-Type: application/x-www-form-urlencoded")]
 [Post("/api/complaints/")]
 Task SubmitComplaint([Body(BodySerializationMethod.UrlEncoded)]SingleComplaint complaint);

And in this is the code that's sending the data

public async Task Post()
{
    SingleComplaint data = new SingleComplaint 
    {
        is_public = ShowPost,
        is_complaint = Complaint,
        show_name = ShowName,
        author = Preferences.Get("UserName", null),
        apt0 = Preferences.Get("Apt", null),
        apartment = Preferences.Get("Apartment", null),
        title = TitleEntry.Text,
        details = DetailsEntry.Text
    };

    try
    {                
        var myApi = RestService.For<IApiService>(Constants.webserver);
        var serialized = JsonConvert.SerializeObject(data);
        ManyComplaints complaint = await myApi.SubmitComplaint(data);
        await DisplayAlert("Thanks", "Your message has been succesfully delivered", "Ok");
    }
    catch (Exception ex)
    {
        await Application.Current.MainPage.DisplayAlert("Error", ex.Message, "Ok");
    }
}

Tried to use the line as string complaint = await myApi.SubmitComplaint(serialized); and also change that as string instead of the ManyComplaints class, also tried to change the model as just the singlecomplaints but I couldn't get it to work, what I'm I missing or how do I make it work?

@ Herb - are you getting any exception ? Also expected response change to var response = await myApi.SubmitComplaint(data); ...this is because your api method is not defined to return any strongly type response object.... if you want ManyComplaints as response object then update your method as Task .... One more thing verify your Api address... may address will be like [Post("/api/complaints")] — Hamid Shaikh, Sep 17 '19 at 06:48
it's returning a null value in my complaint variable and I'm getting server 500 in the app, I dont quite get this from refit it's the first time I use it and not much examples around, adrees is correct :( — Herb, Sep 17 '19 at 13:46

This answer might have come very late. But recently I was working on a similar use case. And the below code worked for me.

API Declaration (using Refit)

[Headers("Content-Type: application/x-www-form-urlencoded")]
[Get("")]
public HttpResponseMessage GetData([Body(BodySerializationMethod.UrlEncoded)] FormUrlEncodedContent content);

Calling the API

List<KeyValuePair<string, string>> contentKey = new List<KeyValuePair<string, string>>
{
    new KeyValuePair<string, string>("apt", "APT"),
    new KeyValuePair<string, string>("apartment", "A103"),
    new KeyValuePair<string, string>("author", "Someone")
};

FormUrlEncodedContent content = new FormUrlEncodedContent(contentKey);

HttpResponseMessage response = someClass.GetData(content);
