Office 365 REST API - Creating a Contact gives me HTTPCode 400

Question

I am using the Office 365 Rest API and I am having problems in creating a Contact:

I am doing this:

public async Task<bool> CreateContact(Contact contact)
    {
        var client = new HttpClient();
        var request = new HttpRequestMessage(HttpMethod.Post, new Uri("https://outlook.office365.com/ews/odata/Me/Contacts"));

        // Add the Authorization header with the basic login credentials.
        var auth = "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(_user + ":" + _password));
        request.Headers.Add("Accept", "application/json");
        request.Headers.Add("Authorization", auth);
        var createResponse = new JObject();
        createResponse["@odata.type"] = "#Microsoft.Exchange.Services.OData.Model.Contact";
        createResponse["DisplayName"] = contact.Name;
        createResponse["EmailAddress1"] = contact.Email;
        request.Content = new StringContent(JsonConvert.SerializeObject(createResponse), Encoding.UTF8, "application/json;odata.metadata=full");
        
        var response = await client.SendAsync(request);
        if (response.IsSuccessStatusCode)
        {
            return true;
        }
        return false;
    }

that give me

{System.FormatException: The format of value 'application/json;odata.metadata=full' is invalid.

   at System.Net.Http.Headers.MediaTypeHeaderValue..ctor(String mediaType)

   at System.Runtime.CompilerServices.AsyncMethodBuilderCore.<ThrowAsync>b__3(Object state)}

but if I change the value "application/json;odata.metadata=full" to "application/json", It gives me 400

saramgsilva, Thanks for trying the API. I tried your code and a couple of things. 1. You need to specify ContentType Header as application/json. Leave the odata part out. 2. After you give that, you would have seen the next issue, which is that Given name is required. Once you provide these two, you should get a 201.

        createResponse["GivenName"] = "Rohit1";
        request.Content = new StringContent(JsonConvert.SerializeObject(createResponse));
        request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
