Prerequisites

• Adyen test account. To start using Adyen APIs, you will need a Merchant Account.
• API key. For testing, your API credential needs to have the API PCI Payments role.
• Node 12 or higher

Installation

You can use NPM to add our library to your project

NPM

npm install --save @adyen/api-library

Alternatively, you can download the release on GitHub.

Using the library

Client initialisation

General use with API key

Set up the client as a singleton resource; you can then use it to create service objects for the API calls that you make to Adyen:

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

General use with API key for live environment

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

General use with basic auth

  const { Client } = require('@adyen/api-library');
  const client = new Client({username: "YOUR_USERNAME", password: "YOUR_PASSWORD", environment: "TEST"});

Consuming Services

Every API the library supports is represented by a service object. The name of the service matching the corresponding API is listed in the Integrations section of this document.

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

  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"
  };
  const checkoutAPI = new CheckoutAPI(client);
  checkoutAPI.payments(paymentRequest)
    .then( paymentResponse => console.log(paymentResponse.pspReference))
    .catch(error => console.log(error));

Alternatively you can make use of the Types included in this library using Typescript, and/or use the async syntax:

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

  import { Types } from '@adyen/api-library';

  const doPaymentsRequest = async ()  => {
    const paymentRequest : 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.payments(paymentRequest);
    console.log(paymentResponse.pspReference);
  }

  doPaymentsRequest();

Custom HTTP Client Configuration

By default, NodeJS https will be used to submit requests to the API. But you can change that by injecting your own HttpClient on your client instance. In the example below, we use axios:

const {Client, Config} = require('@adyen/api-library');
const axios = require("axios");
...
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;
    }
  }
});
...

Proxy configuration

You can configure a proxy connection by injecting your own HttpURLConnectionClient on your client instance and changing the proxy setter value.

Example:

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