I have a website with online transaction using paypal as payment option. Checkout and the shopping cart calculations on paypal side are working, but i'm not receiving any IPN messages from paypal sandbox. after writing the log I found out that parameter formdata is null. Even checked with the IPN history and it shows the status of IPN message as retrying... IPN notification url has also been set.
Below is the listener code.
[Route("IPN")]
public IHttpActionResult IPN(FormDataCollection formData)
{
var formVals = new Dictionary<string, string>();
formVals.Add("cmd", "_notify-validate");
string response = GetPayPalResponse(formVals, formData);
if (response.ToUpper().Trim() == "VERIFIED")
{
//entry into database
}
else
{
return InternalServerError();
}
return InternalServerError();
}
string GetPayPalResponse(Dictionary<string, string> formVals, FormDataCollection formData)
{
string paypalUrl = GetPayPalURL();
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(paypalUrl);
// Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
Encoding encoding = Encoding.UTF8;
StringBuilder sb = new StringBuilder();
foreach (var entry in formData.ToList())
{
sb.AppendFormat("{0}={1}&", entry.Key, encoding.GetString(encoding.GetBytes(entry.Value)));
}
string strRequest = sb.ToString();
strRequest += "cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream());
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
return strResponse;
}
This was working before, but no idea what had stopped it.
Being new to paypal payment gateway, any help would be highly appreciated.
There is a certain problem with paypal since yesterday. I hope it is a remporary issue and it will be fixed asap. I have problems with sandbox myself, but it has happened before as well.
I am also having problems with Sandbox mode... can anyone else confirm this? I am using .NET SDK and adaptive payments...
EDIT: all working again today ;)

I'm trying to do repeat payments with Form Integration in Sagepay (now Opayo).
From an earlier problem posted on here, I get that the securitykey is needed but is not returned in the Form call, so an additional call needs to be made to the getTransactionDetails command.
I have the securitykey and can now make a call to https://test.sagepay.com/gateway/service/repeat.vsp to initiate the repeat payment. However, the documentation does not say where the response to that call goes. I assume therefore, that it would go to the NotificationURL that is set up with a payment when using the Server or Direct integrations. Since I'm using Form, this is not set.
The question is, is there any way of capturing the response to the https://test.sagepay.com/gateway/service/repeat.vsp call if the initial payment was created using Form integration?
I suppose the second question is, has anybody successfully made repeat payments work with Sagepay Form integration?
Not sure if this helps you and we didn't do repeat payments; but we are looking at releasing deferred payments and I think it is a similar approach.
How do you make the call to 'https://test.sagepay.com/gateway/service/repeat.vsp'?
Could you use a 'HttpWebRequest' to make the call then capture the direct response in 'HttpWebResponse'?
EG:
private static void DeferredSharedApiCall(Dictionary<string, string> data, string type, string url)
{
string postData = string.Join("&", data.Select(x => $"{x.Key}={HttpUtility.UrlEncode(x.Value)}"));
HttpWebRequest request = WebRequest.CreateHttp(url);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
using (TextWriter tw = new StreamWriter(request.GetRequestStream()))
{
tw.Write(postData);
}
HttpWebResponse response = null;
try
{
response = request.GetResponse() as HttpWebResponse;
}
catch (WebException ex)
{
//log.Error($"{type} Error, data: {postData}", ex);
}
catch (Exception ex)
{
//log.Error($"{type} Error, data: {postData}", ex);
}
if (response != null)
{
using (TextReader tr = new StreamReader(response.GetResponseStream()))
{
string result = tr.ReadToEnd();
//log.Info($"{type} Response: {Environment.NewLine}{result}");
}
}
}
I am creating a bot to proactively start a conversation with an account I have never had a previous conversation with. I have created another controller that I am posting to and doing the following steps:
public class OutboundController : ApiController {
public HttpResponseMessage Post([FromUri] int id, [FromBody] OutboundData outboundData) {
MicrosoftAppCredentials.TrustServiceUrl(outboundData.ServiceUrl);
//create conversation
var connector = new ConnectorClient(new Uri(outboundData.ServiceUrl));
var botAccount = new ChannelAccount { Id = outboundData.FromAccountId, Name = outboundData.FromAccountName };
var toAccount = new ChannelAccount { Id = outboundData.ToAccountId, Name = outboundData.ToAccountName };
if(!MicrosoftAppCredentials.IsTrustedServiceUrl(outboundData.ServiceUrl)) {
throw new Exception("service URL is not trusted!");
}
var conversationResponse = connector.Conversations.CreateDirectConversation(botAccount, toAccount);
var client = new BuslogicClient();
var confirmData = client.GetOutboundData(id);
var greetingMessage = CreateGreetingMessage(confirmData);
var convoMessage = Activity.CreateMessageActivity();
convoMessage.Text = greetingMessage;
convoMessage.From = botAccount;
convoMessage.Recipient = toAccount;
convoMessage.Conversation = new ConversationAccount(id: conversationResponse.Id);
convoMessage.Locale = "en-Us";
connector.Conversations.SendToConversationAsync((Activity)convoMessage);
string message = string.Format("I received correlationid:{0} and started conversationId:{1}", id, conversationResponse.Id);
var response = Request.CreateResponse(HttpStatusCode.OK, message);
return response;
}
When I call connector.Conversations.CreateDirectConversation I am getting the following exception: Additional information: Authorization for Microsoft App ID [ID] failed with status code Unauthorized and reason phrase 'Unauthorized'. If I do this with appId and password blank everything works fine in the channel emulator. I've tried providing the MicrosoftAppCredentials to the constructor of the ConnectorClient, but that has no affect. I've read on other threads that the service URL must be trusted so I used MicrosoftAppCredentials.TrustServiceUrl.
versions I am using:
BotBuilder 3.5.3
Channel Emulator 3.0.0.59
The use-case for my bot is to post to the outbound controller with some user info to create a proactive message to be sent out (specifically SMS). If the user responds to my message it will be intercepted by the messages controller and passed to my dialogs for further processing and conversation responses on that same channel.
I've also taken a look at: https://github.com/Microsoft/BotBuilder/issues/2155 but don't quite understand solution described in the comments or if it even pertains to the issue I'm trying to solve.
Any suggestions or help would be appreciated!
You need to pass credentials explicitly to connector:
var credentials = new MicrosoftAppCredentials("YoursMicrosoftAppId", "YoursMicrosoftAppPassword");
var connector = new ConnectorClient(serviceUrl, credentials);
Having built an app using PCL method in Xamarin and have had it working 100% using standard HTTP I now changed the remote test server to use SSL with self signed certs.
The app contacts a custom API for logging onto a server and querying for specific data.
I've changed the app to look at SSL now and initially got an error regarding Authentication not working or something but turned off SSL related errors for testing using:
ServicePointManager.ServerCertificateValidationCallback += (o, certificate, chain, errors) => true;
in my AppDelegate files FinishedLaunching method which got over that error.
I'm now getting a 404 / protocol error when trying to do my Login POST to the given URL.
I am using HttpWebRequest for my RESTful calls and this works fine if I change back to plain http.
Not sure why but some articles suggested using ModernHttpClient, which I did. I imported the component (also added the package using NuGet) to no avail.
Am I missing something else that I should be configuring in my code related to httpwebresponse when contacting the SSL server or is this component simply incapable of speaking to an SSL server?
My login function is as follows (Unrelated code removed/obfuscated):
public JsonUser postLogin(string csrfToken, string partnerId, string username, string password){
string userEndPoint = SingletonAppSettngs.Instance ().apiEndPoint;
userEndPoint = userEndPoint.Replace ("druid/", "");
var request = WebRequest.CreateHttp(string.Format(this.apiBaseUrl + userEndPoint + #"user/login.json"));
// Request header collection set up
request.ContentType = "application/json";
request.Headers.Add ("X-CSRF-Token", csrfToken);
// Add other configs
request.Method = "POST";
using (var streamWriter = new StreamWriter(request.GetRequestStream()))
{
string json_body_content = "{\"username\":\"" + username + "\",\"password\":\"" + password + "\"}";
streamWriter.Write(json_body_content);
streamWriter.Flush();
streamWriter.Close();
}
try{
HttpWebResponse httpResponse = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader (httpResponse.GetResponseStream ())) {
var content = reader.ReadToEnd ();
content = content.Replace ("[],", "null,");
content = content.Replace ("[]", "null");
if (content == null) {
throw new Exception ("request_post_login - content is NULL");
} else {
JsonSerializerSettings jss = new JsonSerializerSettings();
jss.NullValueHandling = NullValueHandling.Ignore;
JsonUser deserializedUser = JsonConvert.DeserializeObject<JsonUser>(content, jss);
if(content.Contains ("Hire company admin user")){
deserializedUser.user.roles.__invalid_name__5 = "Hire company admin user";
deserializedUser.user.roles.__invalid_name__2 = "authenticated user";
}
return deserializedUser;
}
}
}catch(Exception httpEx){
Console.WriteLine ("httpEx Exception: " + httpEx.Message);
Console.WriteLine ("httpEx Inner Exception: " + httpEx.InnerException.Message);
JsonUser JsonUserError = new JsonUser ();
JsonUserError.ErrorMessage = "Error occured: " + httpEx.Message;
return JsonUserError;
}
}
When making a Web Request using ModernHttpClient, I generally follow the pattern below. Another great library created by Paul Betts is refit, and can be used to simplify rest calls.
using (var client = new HttpClient(new NativeMessageHandler(false, false)))
{
client.BaseAddress = new Uri(BaseUrl, UriKind.Absolute);
var result = await Refit.RestService.For<IRestApi>(client).GetData();
}
The second parameter for NativeMessageHandler should be set to true if using a customSSLVerification.
Here's a look at IRestApi
public interface IRestApi
{
[Get("/foo/bar")]
Task<Result> GetMovies();
}
Number of things I had to do to get this to work.
The Self Signed Cert had to allow TLS 1.2
As the API is Drupal based, HTTPS had to be enabled on the server and a module installed to manage the HTTP specific pages.
Am getting Invalid response from IPN, some people mentioned like return url and notification url shouldn't be same but i changed in that way also even am getting same result.
Here is my code for making payment,payment is working fine.
Paypal paypal = new Paypal();
paypal.cmd = "_xclick";
paypal.business = ConfigurationManager.AppSettings["BusinessAccountKey"];
bool useSandbox = Convert.ToBoolean(ConfigurationManager.AppSettings["UseSandbox"]);
paypal.cancel_return = "http://www.patronalerts.com/";
//paypal.#return = ConfigurationManager.AppSettings["ReturnURL"];
paypal.#return = "http://www.patronalerts.com/";
paypal.notify_url = ConfigurationManager.AppSettings["NotifyURL"];
paypal.currency_code = ConfigurationManager.AppSettings["CurrencyCode"];
paypal.item_name = "Test Product";
paypal.amount = "10";
url = "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd="+paypal.cmd +"&business="+ paypal.business+"&no_shipping=&return="+paypal.#return+"&cancel_return="+paypal.cancel_return+"¤cy_code="+paypal.currency_code+"&item_name="+ paypal.item_name+"&amount="+ paypal.amount;
But the problem with below code or configuration in paypal account i can't guess. most probably with paypal configuration because every one using this code.
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(System.Web.HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
string strResponse_copy = strRequest; //Save a copy of the initial info sent by PayPal
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
if (strResponse == "VERIFIED")
{
NameValueCollection these_argies = HttpUtility.ParseQueryString(strResponse_copy);
string user_email = these_argies["payer_email"];
string pay_stat = these_argies["payment_status"];
if (pay_stat.Equals("Completed"))
{
ViewBag.Result = "Kishore Suceess";
}
}
else if (strResponse == "INVALID")
{
ViewBag.Result = "invalids";
}
else
{
ViewBag.Result = "Ipn data for manual investigation";
}
If any body help me out would be appriciated.
An “INVALID” message is due to the following reasons:
- Check that your are posting your response to the correct URL, which is https://www.sandbox.paypal.com/cgi-bin/webscr or https://www.paypal.com/cgi-bin/webscr, depending on whether you are testing in the Sandbox or you are live, respectively.
- Verify that your response to the test IPN message contains exactly the same variables and values as the test message and that they are in the same order as in the test message. Finally, verify that the original variables are preceded by a cmd=_notify-validate variable.
- Ensure that you are encoding your response string and are using the same character encoding as used by the test IPN message. (for example, I can see that he is using letters with umlaut and other symbols like “/”, etc).
With regard to the last point, the merchant can try to change the encoding language in use in his PayPal account, following the steps below:
Login on you PayPal account
Click on Profile
Click on “My Selling Preferences” tab
Click on “PayPal Button Language Encoding” (at the end of the page)
Click on "Other Options"
Select from the drop down menu: UTF-8
Choose the same charset also for the second option, which is related to IPN
Click “Save”
If the issue persists, we recommend to review the script in use, PayPal has some IPN code samples available at: https://github.com/paypal/ipn-code-samples
For additional information I include the link: https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNTesting/#id091GFE00WY4
This thing is dragging me nuts.
I have a .net 4.0 console app and I have an MVC web app.
javascript clients can connect and talk to the server - no problems here...
but my .net client throws System.AggregateException with InnerException = "Unexpected character encountered while parsing value: <. Path...
so I created an empty MVC3 app, added SignalR libraries, and .net client surprisingly connects to that. But for some reason it doesn't to the other one. I've checked everything, both MVC3 apps, both use the same SignalR libs, the same NewtonsoftJson... I thought it must be something with the routing, I guess no - js client works.
var connection = new HubConnection("http://localhost:58746");
var hubProxy = connection.CreateProxy("myProxy");
connection.Start().Wait() // it fails here on Wait
What could it be?
UPD: I have figured... it's because FormsAuthentication on the server. Now is there any way to feed .ASPXAUTH cookie to SignalR so it can connect to the server?
The solution by Agzam was really helpful, but if anyone else uses the posted code it is critical that you close the HttpWebResponse before exiting GetAuthCookie. If you don't you will find that whenever you use SignalR to invoke a method on the server, the request (under most circumstances) will queue indefinitely on the client and will neither succeed nor fail.
Note. The original code worked in the test environment when everything was on my PC, but failed consistently when the website was hosted on a remote server.
here is the modified code I ended up using
private Cookie GetAuthCookie(string user, string pass)
{
var http = WebRequest.Create(_baseUrl+"Users/Login") as HttpWebRequest;
http.AllowAutoRedirect = false;
http.Method = "POST";
http.ContentType = "application/x-www-form-urlencoded";
http.CookieContainer = new CookieContainer();
var postData = "UserName=" + user + "&Password=" + pass + "&RememberMe=true&RememberMe=false&ReturnUrl=www.google.com";
byte[] dataBytes = System.Text.Encoding.UTF8.GetBytes(postData);
http.ContentLength = dataBytes.Length;
using (var postStream = http.GetRequestStream())
{
postStream.Write(dataBytes, 0, dataBytes.Length);
}
var httpResponse = http.GetResponse() as HttpWebResponse;
var cookie = httpResponse.Cookies[FormsAuthentication.FormsCookieName];
httpResponse.Close();
return cookie;
}
its a very minor change , but it will save you a lot of debugging time.
Ok... stupid me... SignalR failed to connect because it cannot breach server's Forms authentication. So what needed to be done is to get the auth cookie and stick it to the HubConnection.CookieContainer...
so I wrote this method method to login with a username and get the cookie:
private Cookie GetAuthCookie(string user, string pass)
{
var http = WebRequest.Create(_baseUrl+"Users/Login") as HttpWebRequest;
http.AllowAutoRedirect = false;
http.Method = "POST";
http.ContentType = "application/x-www-form-urlencoded";
http.CookieContainer = new CookieContainer();
var postData = "UserName=" + user + "&Password=" + pass + "&RememberMe=true&RememberMe=false&ReturnUrl=www.google.com";
byte[] dataBytes = System.Text.Encoding.UTF8.GetBytes(postData);
http.ContentLength = dataBytes.Length;
using (var postStream = http.GetRequestStream())
{
postStream.Write(dataBytes, 0, dataBytes.Length);
}
var httpResponse = http.GetResponse() as HttpWebResponse;
var cookie = httpResponse.Cookies[FormsAuthentication.FormsCookieName];
httpResponse.Close();
return cookie;
}
And used it like this:
var connection = new HubConnection(_baseUrl)
{
CookieContainer = new CookieContainer()
};
connection.CookieContainer.Add(GetAuthCookie(_user, _pass));
Works perfectly!
Just use this for reading cookies:
var cookie = response.Cookies[".AspNet.ApplicationCookie"];
