Adyen Node.js API Library

This is the officially supported NodeJS library for using Adyen's APIs.

Integration

The Library supports all APIs under the following services:

• Checkout API: Our latest integration for accepting online payments. Current supported version: v68
• Payments API: Our classic integration for online payments. Current supported version: v64
• Recurring API: Endpoints for managing saved payment details. Current supported version: v49
• Payouts API: Endpoints for sending funds to your customers. Current supported version: v64
• Platforms APIs: Set of APIs when using Adyen for Platforms.
  • Account API Current supported version: v6
  • Fund API Current supported version: v6
  • Notification Configuration API Current supported version: v6
• Local/Cloud-based Terminal API: Our point-of-sale integration.
• BIN lookup API: The BIN Lookup API provides endpoints for retrieving information based on a given BIN. Current supported version: v50

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

Prerequisites

• Adyen test account
• API key. For testing, your API credential needs to have the API PCI Payments role.
• Node 10 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

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

General use with API key for live environment

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

General use with basic auth

    const client = new Client({username: "YOUR_USERNAME", password: "YOUR_PASSWORD", environment: "TEST"});

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;
...
