Usage

1. Update /config/local_env.yml with your API key, Client Key - Remember to add http://localhost:8080 as an origin for client key, and merchant account name (all credentials are in string format):

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:

1. Provide a way for the Adyen platform to reach your running application
2. 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

  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.
