Send JSON data to a different URL

Question

Send JSON data to a different URL

I am facing an issue where I need to send some JSON data to a specific URL. However, when I include all my JSON and token information in the request, the system does not seem to receive the JSON content.

I have verified that the content is present, but it seems like the server does not recognize it as JSON values.

string apiKeyToken = model.reepaytoken; // TOKEN HERE.

string URLLink = APIClassPay.HelperPay.CreateCustomerURL;//URL to send the JSON data to.

WebClient client = new WebClient();
            //JSON data being sent here!
var JSONCustomer = APIClassPay.HelperPay.CreateCustomer(model.Brugernavn, model.Adresse, model.Byen, model.Postnr.ToString(), model.Mobil.ToString(), model.Fornavn, model.Efternavn);
client.Headers.Add("text/json", JSONCustomer);
client.Headers.Set("X-Auth-Token", apiKeyToken);
string reply = client.DownloadString(URLLink);

Upon sending my JSON data, it appears like this:

[HttpPost]
public ActionResult information(BuyMedlemskabViewModel model)
{
    DataLinqDB db = new DataLinqDB();
    var Pric = db.PriceValues.FirstOrDefault(i => i.id == model.HiddenIdMedlemskab);
    if (Pric != null)
    {
        string _OrderValue = DateTime.Now.Year + Helper.Settings.PlanValue();
        Session[HelperTextClass.HelperText.SessionName.OrderId] = _OrderValue;

        Session[HelperTextClass.HelperText.SessionName.FakturaId] = model.HiddenIdMedlemskab;

        Session[HelperTextClass.HelperText.SessionName.fornavn] = model.Fornavn;
        Session[HelperTextClass.HelperText.SessionName.efternavn] = model.Efternavn;
        Session[HelperTextClass.HelperText.SessionName.Adresse] = model.Adresse;
        Session[HelperTextClass.HelperText.SessionName.Post] = model.Postnr;
        Session[HelperTextClass.HelperText.SessionName.Byen] = model.Byen;
        Session[HelperTextClass.HelperText.SessionName.Mobil] = model.Mobil;


        string apiKeyToken = model.reepaytoken;.

        string URLLink = APIClassPay.HelperPay.CreateCustomerURL;//URL to send the JSON data to.

        WebClient client = new WebClient();
        //JSON data being sent here!
        var JSONCustomer = APIClassPay.HelperPay.CreateCustomer(model.Brugernavn, model.Adresse, model.Byen, model.Postnr.ToString(), model.Mobil.ToString(), model.Fornavn, model.Efternavn);
        client.Headers.Add("text/json", JSONCustomer);
        client.Headers.Set("X-Auth-Token", apiKeyToken);
        string reply = client.DownloadString(URLLink);


    }
    return RedirectToAction("information");
}

Answer №1

It seems like there are a few things that need to be corrected:

First, it appears that you are trying to create a resource using the WebClient's DownloadString method, which actually performs a GET request. You should consider using a POST or PUT request instead, depending on the requirements of the web service.

Additionally, it seems like you have placed the payload (customer JSON) in the Content-Type header, when it should be included in the request body.

Based on your previous questions, I assume you are working with either PayPal or QuickPay. If it's QuickPay, I recommend using their official .NET client instead of the WebClient.

For making HTTP requests, it is advisable to use HttpClient over WebClient. Here is an example code snippet:

using (var httpClient = new HttpClient())
{
    var request = new HttpRequestMessage(HttpMethod.Post, APIClassPay.HelperPay.CreateCustomerURL); 
    request.Headers.Add("X-Auth-Token", apiKeyToken); 
    request.Headers.Add("Content-Type", "application/json");
    request.Content = new StringContent(JSONCustomer);
    
    var response = await httpClient.SendAsync(request);
}

EDIT:

As clarified in a comment, the service being used is Reepay. According to the documentation for the create customer method, the necessary HTTP method is POST. The provided code snippet should work accordingly.

If you encountered a compilation error, make sure to correct any mistakes in the variable names and ensure that the keyword 'await' is included as required. Additionally, consider updating your project's .NET framework version to 4.6.1 for proper async/await functionality.
