Adyen 3D Secure 2 Authentication Integration Example

Description

This repository shows the Native and Redirect flows for integrating 3DS2 payments using Adyen.Drop-in and Components. We will go over the integration with the sessions flow and the advanced flow.

Note: We've included a technical blog post that explains every step of this demo.

For additional information, refer to our documentation on testing 3DS2.

Prerequisites

  • Node.js 20+

This demo leverages Adyen's API Library for Node.js (GitHub | Docs).

1. Installation

  1. Clone this repo:
git clone https://github.com/adyen-examples/adyen-node-online-payments.git
  1. Build the frontend and backend. Navigate to the /3ds2-example and install dependencies:

The frontend directory is our client app. This is bootstrapped by Vite: a basic HTML web app with vanilla JavaScript.

The backend directory is our backend app. This is bootstrapped by NestJS and is written in TypeScript. This handles the native or redirect 3DS2, see services:

cd 3ds2-example/frontend && npm install
cd 3ds2-example/backend && npm install

2. Set the Environment Variables

  1. Create a ./.env file in the /frontend-folder with all required configuration & run npm install.
ADYEN_CLIENT_KEY=YOUR_ADYEN_CLIENT_KEY
  1. Create a ./.env file in the /backend-folder with all required configuration & run npm install.
ADYEN_API_KEY=YOUR_ADYEN_API_KEY
ADYEN_MERCHANT_ACCOUNT=YOUR_ADYEN_MERCHANT_ACCOUNT

Note: You can use .env.example as reference.

  1. In your Customer Area, remember to include http://localhost:8080 in the list of Allowed Origins to allow the Adyen.Drop-in/Components to load. Otherwise an 'Invalid Origin'-error will occur.

3. Run the fullstack application

Once you have your .env file created and dependencies installed for both apps we can run both apps concurrently from the root directory:

npm install
npm run fullstack

This command will use the concurrently library to run both apps at the same time from one command.

The backend server should start up at http://localhost:3000 and the frontend server at http://localhost:8080.

4. Usage

  1. Visit http://localhost:8080
  2. Select your integration-type and flow
  3. Select Card and enter a Test Card Number that triggers the 3DS2 flow.

Testing webhooks

Webhooks deliver asynchronous notifications and it is important to test them during the setup of your integration. For this integration, the goal is to showcase the native and redirect 3DS2 flows. Hence why we do not need to set up these when running this demo. For more information, read this detailed blog post.
