Payments API	v68	Our classic integration for online payments.	ClassicIntegrationAPI
Payouts API	v68	Endpoints for sending funds to your customers.	Payout
Platforms APIs	-	Set of APIs when using Adyen for Platforms. This API is used for the classic integration.	Platforms
Account API	v6	Provides endpoints for managing account-related entities on your platform. These related entities include account holders, accounts, bank accounts, shareholders, and verification-related documents.	Account
Fund API	v6	Provides endpoints for managing the funds in the accounts on your platform. These management operations include, for example, the transfer of funds from one account to another, the payout of funds to an account holder, and the retrieval of balances in an account.	Fund
Hosted onboarding API	v6	Provides endpoints that you can use to generate links to Adyen-hosted pages, such as an onboarding page or a PCI compliance questionnaire. You can provide these links to your account holders so that they can complete their onboarding.	HostedOnboardingPage
Notification Configuration API	v6	Provides endpoints for setting up and testing notifications that inform you of events on your platform, for example when a verification check or a payout has been completed.	NotificationConfiguration
POS Terminal Management API	v1	Endpoints for managing your point-of-sale payment terminals.	TerminalManagement
Recurring API	v68	Endpoints for managing saved payment details.	Recurring
Stored Value API	v46	Manage both online and point-of-sale gift cards and other stored-value cards.	StoredValue
Transfers API	v4	The Transfers API provides endpoints that can be used to get information about all your transactions, move funds within your balance platform or send funds from your balance platform to a transfer instrument.	Transfers
Disputes API	v30	You can use the Disputes API to automate the dispute handling process so that you can respond to disputes and chargebacks as soon as they are initiated. The Disputes API lets you retrieve defense reasons, supply and delete defense documents, and accept or defend disputes.	Disputes
POS Mobile API	v68	The POS Mobile API is used in the mutual authentication flow between an Adyen Android or iOS POS Mobile SDK and the Adyen payments platform. The POS Mobile SDK for Android or iOS devices enables businesses to accept in-person payments using a commercial off-the-shelf (COTS) device like a phone. For example, Tap to Pay transactions, or transactions on a mobile device in combination with a card reader	POS Mobile

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

Before you begin

Before you begin to integrate:

Installation

Install the Node.JS package:

npm install --save @adyen/api-library

Alternatively, you can download the release on GitHub.

Updating

To update the Node.JS package:

npm update @adyen/api-library

Check for breaking changes on the releases page.

Usage

// Step 1: Require the parts of the module you want to use
const { Client, CheckoutAPI} = require('@adyen/api-library');

// Step 2: Initialize the client object
const client = new Client({apiKey: "YOUR_API_KEY", environment: "TEST"}); 

// Step 3: Initialize the API object
const checkoutApi = new CheckoutAPI(client);

// Step 4: Create the request object
  const paymentRequest = {
    amount: {
      currency: "USD",
      value: 1000 // value in minor units
    },
    reference: "Your order number",
    paymentMethod: {
      type: "scheme",
      encryptedCardNumber: "test_4111111111111111",
      encryptedExpiryMonth: "test_03",
      encryptedExpiryYear: "test_2030",
      encryptedSecurityCode: "test_737"
    },
    shopperReference: "YOUR_UNIQUE_SHOPPER_ID_IOfW3k9G2PvXFu2j",
    storePaymentMethod: true,
    shopperInteraction: "Ecommerce",
    recurringProcessingModel: "CardOnFile",
    returnUrl: "https://your-company.com/...",
    merchantAccount: "YOUR_MERCHANT_ACCOUNT"
  };
  
// Step 5: Make the request
checkoutApi.PaymentsApi.payments(paymentRequest)
  .then(paymentResponse => console.log(paymentResponse.pspReference))
  .catch(error => console.log(error));

If you want to pass query string parameters, you can use the params field from IRequest (also used for idempotency-key and other header fields). The method descriptions contain an example of the possible values you can send to the API for the query parameters, just as stated in the API explorer.

const requestOptions: IRequest.Options = {
    params: {
        limit: "5",
        offset: "10"
    }
};
await balancePlatformService.AccountHoldersApi.getAllBalanceAccountsOfAccountHolder("AH32272223222B5CM4MWJ892H", requestOptions);

Step 1: Require the parts of the module you want to use

Use the Node.js require function to load the Client and API objects from the Adyen module. For the name of the API objects, see Supported APIs.

For example, to use the Checkout API:

const { Client, CheckoutAPI} = require('@adyen/api-library');

Step 2: Initialize the client object

Initialize the client object, passing the following:

apiKey: The API key you generated from the Customer Area.
environment: For the test environment, use TEST. For the live environment, use LIVE.

For example:

const client = new Client({apiKey: "YOUR_API_KEY", environment: "TEST"});

Step 3: Initialize the API object

Initialize the API object you want to use, passing the client object from the previous step.

For example, for the Checkout API:

const checkoutApi = new CheckoutAPI(client);

Step 4: Create the request object

Create a the request object. For example, for a request to the /payments endpoint:

  const paymentRequest = {
    amount: {
      currency: "USD",
      value: 1000 // value in minor units
    },
    reference: "Your order number",
    paymentMethod: {
      type: "scheme",
      encryptedCardNumber: "test_4111111111111111",
      encryptedExpiryMonth: "test_03",
      encryptedExpiryYear: "test_2030",
      encryptedSecurityCode: "test_737"
    },
    shopperReference: "YOUR_UNIQUE_SHOPPER_ID_IOfW3k9G2PvXFu2j",
    storePaymentMethod: true,
    shopperInteraction: "Ecommerce",
    recurringProcessingModel: "CardOnFile",
    returnUrl: "https://your-company.com/...",
    merchantAccount: "YOUR_MERCHANT_ACCOUNT"
  };

Step 5: Make the request

Use the API object's method to make the request. For example, to make a request to the /payments endpoint using the CheckoutAPI object:

checkoutApi.PaymentsApi.payments(paymentRequest)
  .then(paymentResponse => console.log(paymentResponse.pspReference))
  .catch(error => console.log(error));

Client setup when going live

For APIS that require your Live URL Prefix (Binlookup, BalanceControl, Checkout, Payout and Recurring) the client is set up as follows in order to start processing live payments:

const { Client } = require('@adyen/api-library');

const client = new Client({apiKey: "YOUR_API_KEY", environment: "TEST", liveEndpointUrlPrefix: "YOUR_LIVE_URL_PREFIX"});

Usage in TypeScript

Alternatively, you can use the Types included in this module for Typescript and async syntax.

  const { Client, CheckoutAPI, Types } = require('@adyen/api-library');
  const client = new Client({apiKey: "YOUR_API_KEY", environment: "TEST"});

  const makePaymentsRequest = async () => {
    const paymentsRequest : Types.checkout.PaymentRequest = {
      amount: {
        currency: "USD",
        value: 1000 // Value in minor units.
      },
      reference: "Your order number",
      paymentMethod: {
        type: Types.checkout.CardDetails.TypeEnum.Scheme,
        encryptedCardNumber: "test_4111111111111111",
        encryptedExpiryMonth: "test_03",
        encryptedExpiryYear: "test_2030",
        encryptedSecurityCode: "test_737"
      },
      shopperReference: "YOUR_UNIQUE_SHOPPER_ID_IOfW3k9G2PvXFu2j",
      storePaymentMethod: true,
      shopperInteraction: Types.checkout.PaymentRequest.ShopperInteractionEnum.Ecommerce,
      recurringProcessingModel: Types.checkout.PaymentRequest.RecurringProcessingModelEnum.CardOnFile,
      returnUrl: "https://your-company.com/...",
      merchantAccount: "YOUR_MERCHANT_ACCOUNT"
    };
    const checkoutAPI = new CheckoutAPI(client);
    const paymentResponse : Types.checkout.PaymentResponse = await checkoutAPI.PaymentsApi.payments(paymentsRequest);
    console.log(paymentResponse.pspReference);
  }

  makePaymentsRequest();

Deserializing JSON Strings

In some setups you might need to deserialize JSON strings to request objects. For example, when using the libraries in combination with Dropin/Components. Please use the built-in deserialization functions:

// Import the required model class
import { checkout } from "../typings";

// Deserialize using built-in ObjectSerializer class
const requestJson: JSON = JSON.parse(`YOUR_JSON_STRING`);
const paymentRequest: checkout.PaymentRequest = await checkout.ObjectSerializer.deserialize(requestJson,"PaymentRequest");

Custom HTTP client configuration

By default, Node.js https is used to make API requests. Alternatively, you can set a custom HttpClient for your Client object.

For example, to set axios as your HTTP client:

const {Client, Config} = require('@adyen/api-library');
const axios = require("axios");
// ... more code
const config = new Config();
const client = new Client({
  config,
  httpClient: {
    async request(endpoint, json, config, isApiKeyRequired, requestOptions) {
        const response = await axios({
            method: 'POST',
            url: endpoint,
            data: JSON.parse(json),
            headers: {
                "X-API-Key": config.apiKey,
                "Content-type": "application/json"
            },
        });

        return response.data;
    }
  }
});
// ... more code

Parsing and Authenticating Banking Webhooks

Parse an AccountHolderNotificationRequest webhook;

let bankingWebhookHandler = new BankingWebhookHandler(YOUR_BANKING_WEBHOOK);
const accountHolderNotificationRequest: AccountHolderNotificationRequest = bankingWebhookHandler.getAccountHolderNotificationRequest();
const genericWebhook = bankingWebhookHandler.getGenericWebhook();

You can also parse the webhook with a generic type, in case you do not know the webhook type in advance. In this case you can check the instance of the webhook in order to parse it to the respective type (or just use it dynamically);

let bankingWebhookHandler = new BankingWebhookHandler(YOUR_BANKING_WEBHOOK);
const genericWebhook = bankingWebhookHandler.getGenericWebhook();

Verify the authenticity (where you retrieve the hmac key from the CA and the signature from the webhook header);

const isValid = hmacValidator.validateBankingHMAC("YOUR_HMAC_KEY", "YOUR_HMAC_SIGNATURE", jsonString)

Management Webhooks

Management webhooks are verified the exact same way as the banking webhooks. To parse them however, instead you use:

let managementWebhookHandler = new ManagementWebhookHandler(YOUR_MANAGEMENT_WEBHOOK);
const genericWebhook = managementWebhookHandler.getGenericWebhook();

Proxy configuration

To configure a proxy connection, set the proxy property of your HttpURLConnectionClient object.

For example:

const {HttpURLConnectionClient, Client, Config} = require('@adyen/api-library');
// ... more code
const config = new Config();
const client = new Client({ config });
const httpClient = new HttpURLConnectionClient();
httpClient.proxy = { host: "http://google.com", port: 8888,  };

client.setEnvironment('TEST');
client.httpClient = httpClient;

// ... more code

Using the Cloud Terminal API Integration

In order to submit In-Person requests with Terminal API over Cloud you need to initialize the client in a similar way as the steps listed above for Ecommerce transactions, but make sure to include TerminalCloudAPI:

// Step 1: Require the parts of the module you want to use
const {Client, TerminalCloudAPI} from "@adyen/api-library";

// Step 2: Initialize the client object
const client = new Client({apiKey: "YOUR_API_KEY", environment: "TEST"});

// Step 3: Initialize the API object
const terminalCloudAPI = new TerminalCloudAPI(client);

// Step 4: Create the request object
const serviceID = "123456789";
const saleID = "POS-SystemID12345";
const POIID = "Your Device Name(eg V400m-123456789)";

// Use a unique transaction for every transaction you perform
const transactionID = "TransactionID";
const paymentRequest: SaleToPOIRequest = {
    MessageHeader: {
        MessageClass: MessageClassType.Service,
        MessageCategory: MessageCategoryType.Payment,
        MessageType: MessageType.Request,
        ProtocolVersion: "3.0",
        ServiceID: serviceID,
        SaleID: saleID,
        POIID: POIID
    },
    PaymentRequest: {
        SaleData: {
            SaleTransactionID: {
                TransactionID: transactionID,
                TimeStamp: this.GetDate().toISOString()
            },

            SaleToAcquirerData: {
                applicationInfo: {
                    merchantApplication: {
                        version: "1",
                        name: "test",
                    }
                }
            }
        },
        PaymentTransaction: {
            AmountsReq: {
                Currency: "EUR",
                RequestedAmount: 1000
            }
        }
    }
};

// Step 5: Make the request
const terminalAPIResponse: terminal.TerminalApiResponse = await terminalCloudAPI.sync(paymentRequest);

Optional: perform an abort request

To perform an abort request you can use the following example:

const abortRequest: SaleToPOIRequest = {
    MessageHeader: {
        MessageClass: MessageClassType.Service,
        MessageCategory: MessageCategoryType.Abort,
        MessageType: MessageType.Request,
        ProtocolVersion: "3.0",
        // Different serviceID than the one you're aborting
        ServiceID: "Different service ID",
        SaleID: saleID,
        POIID: POIID
    },
    AbortRequest: {
        AbortReason: "MerchantAbort",
        MessageReference: {
            MessageCategory: MessageCategoryEnum.Payment,
            SaleID: saleID,
            // Service ID of the payment you're aborting
            ServiceID: serviceID,
            POIID: POIID
        }

    }
};
const terminalAPIResponse: terminal.TerminalApiResponse = await terminalCloudAPI.sync(abortRequest);

Optional: perform a status request

To perform a status request you can use the following example:

const statusRequest: SaleToPOIRequest = {
    MessageHeader: {
        MessageClass: MessageClassType.Service,
        MessageCategory: MessageCategoryType.TransactionStatus,
        MessageType: MessageType.Request,
        ProtocolVersion: "3.0",
        ServiceID: "Different service ID",
        SaleID: saleID,
        POIID: POIID
    },
    TransactionStatusRequest: {
        ReceiptReprintFlag: true,
        DocumentQualifier: [DocumentQualifierEnum.CashierReceipt, DocumentQualifierEnum.CustomerReceipt],
        MessageReference: {
            SaleID: saleID,
            // serviceID of the transaction you want the status update for
            ServiceID: serviceID,
            MessageCategory: MessageCategoryEnum.Payment
        }
    }
};
const terminalAPIResponse: terminal.TerminalApiResponse = await terminalCloudAPI.sync(statusRequest);

Using the Local Terminal API Integration

The procedure to send In-Person requests using Terminal API over Local Connection is similar to the Cloud Terminal API one, however, additional encryption details are required to perform the requests. Make sure to install the certificate as described here

// Step 1: Require the parts of the module you want to use
const {Client, TerminalLocalAPI} from "@adyen/api-library";

// Step 2: Add your Certificate Path and Local Endpoint to the config path. Install the certificate and save it in your project folder as "cert.cer"
const config: Config = new Config();
config.certificatePath = "./cert.cer";
config.terminalApiLocalEndpoint = "The IP of your terminal (eg https://192.168.47.169)";
config.apiKey = "YOUR_API_KEY_HERE";

// Step 3: Setup a security password for your terminal in CA, and import the security key object:
const securityKey: SecurityKey = {
    AdyenCryptoVersion: 1,
    KeyIdentifier: "keyIdentifier",
    KeyVersion: 1,
    Passphrase: "passphrase",
};

// Step 4 Initialize the client and the API objects
client = new Client({ config });
const terminalLocalAPI = new TerminalLocalAPI(client);

// Step 5: Create the request object
const paymentRequest: SaleToPOIRequest = {
// Similar to the saleToPOIRequest used for Cloud API
}

// Step 6: Make the request
const terminalApiResponse: terminal.TerminalApiResponse = await terminalLocalAPI.request(paymentRequest, securityKey);

Using the Local Terminal API Integration without Encryption (Only on TEST)

If you wish to develop the Local Terminal API integration parallel to your encryption implementation, you can opt for the unencrypted version. Be sure to remove any encryption details from the CA terminal config page.

// Step 1: Require the parts of the module you want to use
const {Client, TerminalLocalAPIUnencrypted} from "@adyen/api-library";

// Step 2: Add your Certificate Path and Local Endpoint to the config path. Install the certificate and save it in your project folder as "cert.cer"
const config: Config = new Config();
config.terminalApiLocalEndpoint = "The IP of your terminal (eg https://192.168.47.169)";
config.apiKey = "YOUR_API_KEY_HERE";

// Step 3 Initialize the client and the API objects
client = new Client({ config });
const terminalLocalAPI = new TerminalLocalAPIUnencrypted(client);

// Step 4: Create the request object
const paymentRequest: SaleToPOIRequest = {
// Similar to the saleToPOIRequest used for Cloud API
}

// Step 5: Make the request
const terminalApiResponse: terminal.TerminalApiResponse = await terminalLocalAPI.request(paymentRequest);
