Guides for Adyen

Step-by-step setup for the most popular AI clients.

Setting up Adyen

From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.

This connector uses the Adyen Checkout API v71 and Payments Modifications API (docs.adyen.com).

Setup:

  1. Sign in to https://ca-test.adyen.com (test) or https://ca-live.adyen.com (live) → Developers → API credentials → New credential → API user.
  2. Generate the API key. Note your merchant account name (visible in top dropdown, e.g. AcmeCo).
  3. Set:
    • ADYEN_API_KEY = the API key
    • ADYEN_MERCHANT_ACCOUNT = the merchant account name
    • ADYEN_ENV = test or live
    • For LIVE only: also set ADYEN_LIVE_URL_PREFIX = the URL prefix Adyen issued you (something like abc123def-AcmeCo). Find in CA → Developers → API URLs.

Authentication: header X-API-Key: ${ADYEN_API_KEY}.

Base URL switches environment: Adyen test → https://checkout-test.adyen.com/v71. Live → https://{PREFIX}-checkout-live.adyenpayments.com/checkout/v71. The adapter uses test by default; for live, point ADYEN_CHECKOUT_BASE_URL env var at the prefixed live URL.

Amount format: {currency: 'EUR', value: 1099} — value in MINOR units (cents). EUR uses 2 decimals, JPY 0 decimals — Adyen handles per ISO 4217. NEVER pass decimals.

Idempotency: pass Idempotency-Key header on POST /payments to dedupe retries.

Payment flow:

  1. adyen_payment_methods — get available methods for currency/country/amount.
  2. adyen_create_payment — create the payment. Response includes resultCode (Authorised/Refused/Pending/RedirectShopper/etc.) and optional action (redirect/3DS challenge).
  3. If action: shopper completes it client-side; server gets back details to submit.
  4. adyen_payments_details — finalize.
  5. Track via adyen_payments_capture (manual capture flow), adyen_payments_refund, adyen_payments_cancel.

Modifications: capture/refund/cancel use the dedicated modification endpoints, NOT the same endpoint as create.

Webhooks out of scope.

Out of scope here: Terminal API (in-person), Balance Platform deep features, Marketpay, Recurring API beyond basic.
