Adyen Checkout API

Number of APIs: 6


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 One-Click and 3D Secure), mobile wallets, and local payment methods (e.g. iDEAL and Sofort).

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

Authentication

Each request to the Checkout 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 API key. Then set this key to the X-API-Key header value, for example:

curl
-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](https://docs.adyen.com/development-resources/live-end
