Pay.nl C# .NET Core SDK - Work in progress?

---

• Quick start and examples

---

This SDK is available as DotNet Assembly.

With this SDK you will be able to start transactions and retrieve transactions with their status for the Pay.nl payment service provider.

Usage

Setting the configuration:

PAYNLSDK.API.RequestBase.ApiToken = "e41f83b246b706291ea9ad798ccfd9f0fee5e0ab";
PAYNLSDK.API.RequestBase.ServiceId = "SL-3490-4320";

Getting a list of available payment methods, use the Getservice.

PAYNLSDK.API.RequestBase.ApiToken = "e41f83b246b706291ea9ad798ccfd9f0fee5e0ab";
PAYNLSDK.API.RequestBase.ServiceId = "SL-3490-4320";
PAYNLSDK.API.Transaction.GetService.Response response = PAYNLSDK.Transaction.GetService(paymentMethodId);
//paymentMethodId: is optional
//The ID of the payment method. Only the payment options linked to the provided payment method ID will be returned if an ID is provided.
//If omitted, all available payment options are returned. Use the following IDs to filter the options:
//1. SMS.
//2. Pay fixed price.
//3. Pay per call.
//4. Pay per transaction
//5. Pay per minute.

Starting a transaction:

PAYNLSDK.API.RequestBase.ApiToken = "e41f83b246b706291ea9ad798ccfd9f0fee5e0ab";
PAYNLSDK.API.RequestBase.ServiceId = "SL-3490-4320";

PAYNLSDK.API.Transaction.Start.Request request = PAYNLSDK.Transaction.CreateTransactionRequest("127.0.0.1", "http://example.org/visitor-return-after-payment");
request.Amount = 621; // Amount in cents

request.PaymentOptionId = 10; // Payment profile/option


// Transaction data
request.Transaction = new PAYNLSDK.Objects.TransactionData();
request.Transaction.Currency = "EUR";
request.Transaction.CostsVat = null;
request.Transaction.OrderExchangeUrl = "https://example.org/exchange.php";
request.Transaction.Description = "TEST PAYMENT"; // Description for client
request.Transaction.ExpireDate = DateTime.Now.AddDays(14);

// Optional Stats data
request.StatsData = new PAYNLSDK.Objects.StatsDetails();
request.StatsData.Info = "your information";
request.StatsData.Tool = "C#.NET";
request.StatsData.Extra1 = "X";
request.StatsData.Extra2 = "Y";
request.StatsData.Extra3 = "Z";

// Initialize Salesdata
request.SalesData = new PAYNLSDK.Objects.SalesData();
request.SalesData.InvoiceDate = DateTime.Now;
request.SalesData.DeliveryDate = DateTime.Now;
request.SalesData.OrderData = new System.Collections.Generic.List<PAYNLSDK.Objects.OrderData>();

// Add products
request.SalesData.OrderData.Add(new PAYNLSDK.Objects.OrderData("SKU-8489", "Testproduct 1", 2995, "H", 1));
request.SalesData.OrderData.Add(new PAYNLSDK.Objects.OrderData("SKU-8421", "Testproduct 2", 995, "H", 1));
request.SalesData.OrderData.Add(new PAYNLSDK.Objects.OrderData("SKU-2359", "Testproduct 3", 2499, "H", 1));

// enduser
request.Enduser = new PAYNLSDK.Objects.EndUser();
request.Enduser.Language = "NL"; // End user language
request.Enduser.Initials = "J.";
request.Enduser.Lastname = "Buyer";
request.Enduser.Gender = PAYNLSDK.Enums.Gender.Male;
request.Enduser.BirthDate = new DateTime(1991, 1, 23, 0, 0, 0, DateTimeKind.Local);
request.Enduser.PhoneNumber = "0612345678";
request.Enduser.EmailAddress = "[email protected]";
request.Enduser.BankAccount = "";
request.Enduser.IBAN = "NL08INGB0000000555";
request.Enduser.BIC = "";

// enduser address
request.Enduser.Address = new PAYNLSDK.Objects.Address();
request.Enduser.Address.StreetName = "Streetname";
request.Enduser.Address.StreetNumber = "8";
request.Enduser.Address.ZipCode = "1234AB";
request.Enduser.Address.City = "City";
request.Enduser.Address.CountryCode = "NL";

// invoice address
request.Enduser.InvoiceAddress = new PAYNLSDK.Objects.Address();
request.Enduser.InvoiceAddress.Initials = "J.";
request.Enduser.InvoiceAddress.LastName = "Jansen";
request.Enduser.InvoiceAddress.Gender = PAYNLSDK.Enums.Gender.Male;
request.Enduser.InvoiceAddress.StreetName = "InvoiceStreetname";
request.Enduser.InvoiceAddress.StreetNumber = "10";
request.Enduser.InvoiceAddress.ZipCode = "1234BC";
request.Enduser.InvoiceAddress.City = "City";
request.Enduser.InvoiceAddress.CountryCode = "NL";

//System.Diagnostics.Debug.WriteLine(request.ToString()); // JSON view of data before sending


PAYNLSDK.API.Transaction.Start.Response response = PAYNLSDK.Transaction.Start(request); // Sending to PAY.

To determine if a transaction has been paid, you can use:

PAYNLSDK.API.RequestBase.ApiToken = "e41f83b246b706291ea9ad798ccfd9f0fee5e0ab";
PAYNLSDK.API.RequestBase.ServiceId = "SL-3490-4320";

PAYNLSDK.API.Transaction.Start.Response response;
// Perform transaction to get response object. Alternately, you could work with a stored ID.

PAYNLSDK.API.Transaction.Info.Response info = PAYNLSDK.Transaction.Info(response.transactionId);
PAYNLSDK.Enums.PaymentStatus result = info.PaymentDetails.State;

if (PAYNLSDK.Transaction.IsPaid(result) || PAYNLSDK.Transaction.IsPending(result))
{
    // redirect user to thank you page
}
else
{
    // it has not been paid yet, so redirect user back to checkout
}

When implementing the exchange script (where you should process the order in your backend):

PAYNLSDK.API.RequestBase.ApiToken = "e41f83b246b706291ea9ad798ccfd9f0fee5e0ab";
PAYNLSDK.API.RequestBase.ServiceId = "SL-3490-4320";

PAYNLSDK.API.Transaction.Info.Response info = PAYNLSDK.Transaction.Info(response.transactionId);
PAYNLSDK.Enums.PaymentStatus result = info.State;

if (PAYNLSDK.Transaction.IsPaid(result))
{
    // process the payment
}
else 
{
 if(PAYNLSDK.Transaction.IsCancelled(result)){
    // payment canceled, restock items
 }
}

response.Write("TRUE| ");
// Optionally you can send a message after TRUE|, you can view these messages in the logs.
// https://admin.pay.nl/logs/payment_state
response.Write("Paid");
