Adyen Checkout API
Click to copy

Adyen Checkout API provides a simple and flexible way to initiate and authorise online payments. You can use the same integration for payments made with cards (including 3D Secure), mobile wallets, and local payment methods (for example, iDEAL and Sofort).

This API reference provides information on available endpoints and how to interact with them. To learn more about the API, visit online payments documentation.


Each request to Checkout API must be signed with an API key. For this, get your API key from your Customer Area, and set this key to the X-API-Key header value, for example:

-H "Content-Type: application/json" \


Checkout API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number.

For example:

Going live

To access the live endpoints, you need an API key from your live Customer Area.

The live endpoint URLs contain a prefix which is unique to your company account, for example:


Get your {PREFIX} from your live Customer Area under Developers > API URLs > Prefix.

When preparing to do live transactions with Checkout API, follow the go-live checklist to make sure you've got all the required configuration in place.
