Go to gitpod account variables.
Set the ADYEN_API_KEY, ADYEN_CLIENT_KEY, ADYEN_HMAC_KEY and ADYEN_MERCHANT_ACCOUNT variables.
Click the button below!

NOTE: To allow the Adyen Drop-In and Components to load, you have to add https://*.gitpod.io as allowed origin for your chosen set of API Credentials

Details

This repository includes examples of PCI-compliant React UI integrations for online payments with Adyen. Within this demo app, you'll find a simplified version of an e-commerce website, complete with commented code to highlight key features and concepts of Adyen's API. Check out the underlying code to see how you can integrate Adyen to give your shoppers the option to pay with their preferred payment methods, all in a seamless checkout experience.

Installation

Clone this repo:

git clone https://github.com/adyen-examples/adyen-react-online-payments.git

Navigate to the root directory and install dependencies:

npm install

Usage

Create a ./.env file with your API key, Client Key - Remember to add http://localhost:3000 as an origin for client key, and merchant account name (all credentials are in string format):

REACT_APP_ADYEN_API_KEY="your_API_key_here"
REACT_APP_ADYEN_MERCHANT_ACCOUNT="your_merchant_account_here"
REACT_APP_ADYEN_CLIENT_KEY="your_client_key_here"
REACT_APP_ADYEN_HMAC_KEY=yourNotificationSetupHMACkey

Build & Start the server:

This will create a React production build and start the express server

npm run server

Visit http://localhost:8080/ to select an integration type.

To try out integrations with test card numbers and payment method details, see Test card numbers.

Note

Cancellation/Refund flow makes use of Adyen webhook notifications. You can use a service like ngrok to configure two Adyen webhooks with below details for test

Notification types: Standard Notification
URL: https://[tempdomain].ngrok.io/api/webhook/notification
Method: JSON
Username: anything
Password: anything

This example doesn't authenticate the webhook, in actual practice you should protect the endpoint with basic authentication and set the same credentials on notification setting above.

Testing webhooks

Webhooks deliver asynchronous notifications and it is important to test them during the setup of your integration. You can find more information about webhooks in this detailed blog post.

This sample application provides a simple webhook integration exposed at /api/webhooks/notifications. For it to work, you need to:

Provide a way for the Adyen platform to reach your running application
Add a Standard webhook in your Customer Area

Making your server reachable

Your endpoint that will consume the incoming webhook must be publicly accessible.

There are typically 3 options:

deploy on your own cloud provider
deploy on Gitpod
expose your localhost with tunneling software (i.e. ngrok)

Option 1: cloud deployment

If you deploy on your cloud provider (or your own public server) the webhook URL will be the URL of the server

  https://{cloud-provider}/api/webhooks/notifications

Option 2: Gitpod

If you use Gitpod the webhook URL will be the host assigned by Gitpod

  https://myorg-myrepo-y8ad7pso0w5.ws-eu75.gitpod.io/api/webhooks/notifications

Note: when starting a new Gitpod workspace the host changes, make sure to update the Webhook URL in the Customer Area

Option 3: localhost via tunneling software

If you use a tunneling service like ngrok the webhook URL will be the generated URL (ie https://c991-80-113-16-28.ngrok.io)

  $ ngrok http 8080
  
  Session Status                online                                                                                           
  Account                       ############                                                                      
  Version                       #########                                                                                          
  Region                        United States (us)                                                                                 
  Forwarding                    http://c991-80-113-16-28.ngrok.io -> http://localhost:8080                                       
  Forwarding                    https://c991-80-113-16-28.ngrok.io -> http://localhost:8080

Note: when restarting ngrok a new URL is generated, make sure to update the Webhook URL in the Customer Area

Set up a webhook

In the Customer Area go to Developers -> Webhooks and create a new 'Standard notification' webhook.
Enter the URL of your application/endpoint (see options above)
Define username and password for Basic Authentication
Generate the HMAC Key
Optionally, in Additional Settings, add the data you want to receive. A good example is 'Payment Account Reference'.
Make sure the webhook is Enabled (therefore it can receive the notifications)

That's it! Every time you perform a new payment, your application will receive a notification from the Adyen platform.

Notice

This project was bootstrapped with Create React App, using the Redux and Redux Toolkit template.

Available Scripts

In the project directory, you can run:

`npm run server-dev`

Runs the Express app in the development mode.
Open http://localhost:8080 to view it in the browser.

The server will reload if you make edits.

`npm start`

Runs the React client side app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

`npm test`

Launches the test runner in the interactive watch mode for React client side.
See the section about running tests for more information.

`npm build`

Builds the React client side app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

`npm eject`

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
