Adyen Checkout Utility Service

A web service containing utility functions available for merchants integrating with Checkout APIs. ## Authentication 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: ``` 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. ## Versioning 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: ``` https://checkout-test.adyen.com/v1/originKeys ```

Plan the first integration safely

The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.

Authentication

OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.

Transport

HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.

Browser access

CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.

First-request sequence

  1. Identify the current base URL, version, and endpoint for the use case.
  2. Confirm how credentials are issued and where they may be stored.
  3. Test success, invalid input, throttling, unavailable data, and timeouts.
  4. Record response fields, pagination, caching, and error shapes.
  5. Add monitoring, retries with backoff, and an appropriate fallback.

Questions to resolve before production

Pricing and quotas

Confirm current plans, free-tier limits, overages, and request ceilings.

Endpoint coverage

Check that the operations and response fields match the intended workload.

Reliability

Look for uptime history, a status page, support routes, and service commitments.

Data and privacy

Review retention, licensing, regional processing, and compliance requirements.

Versioning

Confirm the active version, change policy, deprecation window, and migration guidance.

Developer experience

Validate SDKs, examples, error formats, pagination, and test environments.
