What you set up

  • Adyen module

  • Test API Key
  • Live API Key
  • Merchant Account
  • Live URL Prefix
  • Notification HMAC Key
  • Checkout session
    A session is created on your merchant account and the buyer is sent to its URL.
  • HMAC verified
    Every notification item is checked on its own with your HMAC key.

What you get

What you can do with Adyen

Live URL Prefix

In live mode, requests go to your account’s own endpoint, found under API URLs.

Test environment

Test uses Adyen’s test Checkout API with your Test API Key.

Notifications decide

The buyer’s return is only a hint, and the authorisation notification sets the result.

FAQ

Questions, answered

Still wondering about Adyen? The documentation covers every setting, and we are happy to help.

Read the documentation

Where do I find the Live URL Prefix?

Under API URLs in your Adyen account. It’s only needed in live mode.

What does the HMAC key do?

It verifies each notification Adyen sends, so an item with a bad signature is ignored.
