HubSpot API POST contacts in batches - json

Question

I am using the API to communicate batches of contacts using the endpoint /contacts/v1/contact/batch/
I get an error message response which reads#
{"status":"error", "message":"Invalid input JSON on line 1, column 1: Can not deserialize instance of java.util.ArrayList out of VALUE_STRING token","correlationId":"3c1488a8-24f5-4e1c-b506-18edcd870065","requestId":"a85c3ea88b60a7d0e3cfe5736c819b11"}
The JSON i am sending is valid. I've checked and double checked.
Please help :(
My output is below

I found the source code I used and will try my best to explain my implementation of it for you.
The application I created was a mobile app that is used by companies to capture information about new prospects and send that information into their HubSpot account.
The main application contains a class of Prospect which defines the information we want to obtain about a prospect
public class Prospect
{
public string CompanyName { get; set; }
public string Website { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string JobTitle { get; set; }
public string Phone { get; set; }
public string Email { get; set; }
public string Products { get; set; }
public string Notes { get; set; }
public string ContactOwner { get; set; }
public string ShowName { get; set; }
}
The component of the application which is relevant to the question you asked contains 2 classes:
public class HubSpotProspect
{
public string email { get; set; }
public List<Property> properties { get; set; }
}
public class Property
{
public string property { get; set; }
public string value { get; set; }
}
The following code gets a list of all the prospects then iterates through them to assign the correct attribute values and translates then into a new list of HubSpotProspect. We then serialise this list into json and pass it to the function that communicates with HubSpot API.
List<Prospect> _pList = _prospectList.GetProspectList(ShowName);
List _hsProspectList = new List();
foreach (Prospect p in _pList)
{
HubSpotProspect _hsp = new HubSpotProspect();
_hsp.email = p.Email;
_hsp.properties = new List<Property>();
_hsp.properties.Add(new Property { property = "company", value = p.CompanyName });
_hsp.properties.Add(new Property { property = "website", value = p.Website });
_hsp.properties.Add(new Property { property = "firstname", value = p.FirstName });
_hsp.properties.Add(new Property { property = "lastname", value = p.LastName });
_hsp.properties.Add(new Property { property = "jobtitle", value = p.JobTitle });
_hsp.properties.Add(new Property { property = "phone", value = p.Phone });
_hsp.properties.Add(new Property { property = "product", value = p.Products });
_hsp.properties.Add(new Property { property = "event_list_2019", value = p.ShowName });
_hsp.properties.Add(new Property { property = "hubspot_owner_id", value = _userProfile.GetContactOwner() });
_hsProspectList.Add(_hsp);
}
string json = JsonConvert.SerializeObject(_hsProspectList);
await SendContact(json);
The function that communicates with the HubSpot API is as follows:
private Task SendContact(string JsonString)
{
return Task.Factory.StartNew(() =>
{
string hapiKey = _userProfile.GetHapiKey();
var client = new RestClient(https://api.hubapi.com/);
var request = new RestRequest("contacts/v1/contact/batch/", Method.POST);
request.AddQueryParameter("hapikey", hapiKey);
request.RequestFormat = DataFormat.Json;
request.AddJsonBody(JsonString);
IRestResponse response = client.Execute<HubSpotProspect>(request);
var content = response.Content;
//Console.WriteLine("RESPONSE " + content);
});
}
