Terminal API (Local communications) Our point-of-sale integration. Local-based Terminal API Local-based Terminal API
POS Terminal Management API This API provides endpoints for managing your point-of-sale (POS) payment terminals. You can use the API to obtain information about a specific terminal, retrieve overviews of your terminals and stores, and assign terminals to a merchant account or store. POSTerminalManagement v1

For more information, refer to our documentation or the API Explorer.


  • Adyen test account
  • API key. For testing, your API credential needs to have the API PCI Payments role.
  • Adyen dotnet API Library supports .net standard 2.0 and above
  • In order for Adyen dotnet API Library to support local terminal api certificate validation the application should be set to .net core 2.1 and above or .net framework 4.6.1 and above


Simply download and restore nuget packages or install it from package manager

PM> Install-Package Adyen -Version x.x.x

Using the library

In order to submit http request to Adyen API you need to initialize the client. The following example makes a checkout payment request:

// Create a paymentsRequest
using Adyen;
using Adyen.Model.Checkout;
using Adyen.Service;
using Environment = Adyen.Model.Enum.Environment;

// Create a paymentsRequest
var amount = new Amount("USD", 1000);
var paymentRequest = new PaymentRequest
    Reference = "Your order number",
    Amount = amount,
    ReturnUrl = @"",
    MerchantAccount = "Your merchantAccount",

//Create the http client
var config = new Config
    XApiKey = "Your merchant XAPI key",
    Environment = Environment.Test
var client = new Client(config);
var checkout = new PaymentsService(client);
//Make the call to the service. This example code makes a call to /payments
var paymentResponse = checkout.Payments(paymentRequest);

Or in case you would like to make an asynchronous /payments call with idempotency key and cancellation token, the last line would be instead:

Task<PaymentResponse> paymentResponse = checkout.PaymentsAsync(
                requestOptions: myIdempotencyKey, 
                cancellationToken: myCancellationToken);

Running the tests

Navigate to adyen-dotnet-api-library folder and run the following commands.

dotnet build
dotnet test

Using the Cloud Terminal API

In order to submit POS request with Cloud Terminal API you need to initialize the client with the Endpoints that it is closer to your region. The Endpoints are available as contacts in ClientConfig For more information please read our documentation

//Example for EU based Endpoint Syncronous
using Adyen;
using Adyen.Constants;

var config = new Config
    XApiKey = "Your merchant XAPI key",
    CloudApiEndPoint = ClientConfig.CloudApiEndPointEULive
var client = new Client(config);

To parse the terminal API notifications, please use the following custom deserializer. This method will throw an exception for non-notification requests.

var serializer = new SaleToPoiMessageSerializer();
var saleToPoiRequest = serializer.DeserializeNotification(your_terminal_notification);

Example Cloud Terminal API integration

using System;
using Adyen.Model.Nexo;
using Adyen.Model.Nexo.Message;
using Adyen.Service;
using Environment = Adyen.Model.Enum.Environment;
namespace Adyen.Terminal
   public static class Program
        private static string XApiKey = "YOUR-API-KEY";
        private static void Main(string[] args)
            var client = new Client(XApiKey, Environment.Test);
            PosPaymentCloudApi posPaymentCloudApi = new PosPaymentCloudApi(client);
            SaleToPOIResponse response = posPaymentCloudApi.TerminalApiCloudSync(PaymentRequest());
            PaymentResponse paymentResponse = (PaymentResponse) response.MessagePayload;
        private static SaleToPOIRequest PaymentRequest()
            var serviceID = "SERVICE_ID"; // ServiceId should be unique for every request
            var saleID = "SALE_ID";
            var POIID = "SERIAL_NUMBER";
            var transactionID = "123459";
            var saleToPOIRequest = new SaleToPOIRequest()
                MessageHeader = new MessageHeader()
                    MessageClass = MessageClassType.Service,
                    MessageCategory = MessageCategoryType.Payment,
                    MessageType = MessageType.Request,
                    ServiceID = serviceID,
                    SaleID = saleID,
                    POIID = POIID
                MessagePayload = new PaymentRequest()
                    SaleData = new SaleData()
                        SaleTransactionID = new TransactionIdentification()
                            TransactionID = transactionID,
                            TimeStamp = DateTime.Now
                    PaymentTransaction = new PaymentTransaction()
                        AmountsReq = new AmountsReq()
                            Currency = "EUR",
                            RequestedAmount = new decimal(10.9)
            return saleToPOIRequest;

Using the Local Terminal API

The request and response payloads are identical to the Cloud Terminal API, however an additional encryption details object is required to send the requests.

var encryptionCredentialDetails = new EncryptionCredentialDetails
        AdyenCryptoVersion = 1,
        KeyIdentifier = "CryptoKeyIdentifier12345",
        Password = "p@ssw0rd123456"
var config = new Config
        Environment = Model.Environment.Live,
        LocalTerminalApiEndpoint = @"https://_terminal_:8443/nexo/"
var client = new Client(config);
var posPaymentLocalApi = new PosPaymentLocalApi(client);
var saleToPOIResponse = posPaymentLocalApi.TerminalApiLocal(paymentRequest, encryptionCredentialDetails);

To parse the terminal API notifications, please use the following custom deserializer. This method will throw an exception for non-notification requests.

var serializer = new SaleToPoiMessageSerializer();
var saleToPoiRequest = serializer.DeserializeNotification(your_terminal_notification);
