Adyen Checkout Utility Service


A web service containing utility functions available for merchants integrating with Checkout APIs.


Each request to the Checkout Utility API must be signed with an API key. For this, obtain an API Key from your Customer Area, as described in How to get the Checkout API key. Then set this key to the X-API-Key header value, for example:

-H "Content-Type: application/json" \
-H "X-API-Key: Your_Checkout_API_key" \

Note that when going live, you need to generate a new API Key to access the live endpoints.


Checkout API supports versioning of its endpoints through a version suffix in the endpoint URL. This suffix has the following format: “vXX”, where XX is the version number.

For example:

Use this page to mock Adyen Checkout Utility Service in your testing and development.

Run our mock API sample using the open source WireMock library, or in the free edition of WireMock Cloud. You'll have a working API server simulating the behavior of Adyen Checkout Utility Service, which will allow you to keep building and testing even if the actual API you isn't currently available.
