購入者は Amazon アカウントに保存済みのカードや情報で支払います — 米国・欧州・英国・日本で最も信頼されるウォレットのひとつです。登録は Amazon Pay Seller Central でセルフサービスで行えますが、旅行・ツアーサービスは制限カテゴリのため、決済を受け付ける前に Amazon の事前承認が必要です（pay.amazon.com/help/6023 参照）。Merchant ID、Store ID、API キーは Seller Central → Integration Central にあります。
Amazon Payでは、お客様はAmazonアカウントに保存済みの支払い方法を使って支払えるため、カード情報を入力せずに予約を完了できます。米国、英国、ヨーロッパ、日本の事業者が利用できます。なお、旅行・ツアーサービスはAmazonの制限カテゴリーであるため、支払いを受け付けるにはAmazonの事前承認が必要です。Amazon Payが支払いを確認すると、TourTaskは自動的に予約を支払い済みとしてマークし、あなたの事業とお客様の両方に確認を送信します。

Amazon Pay lets customers pay with what their Amazon account already holds. Registration is self-serve, but plan for one approval step: travel and tour services are a restricted category, and Amazon must approve your business for it before you can charge.
Sign up at pay.amazon.com for your region — Amazon Pay serves merchants in the US, the UK, Japan and 15 European countries — which opens Amazon Pay Seller Central for your account. Then request approval for the travel category (Amazon's policy page is pay.amazon.com/help/6023): apply before you plan to go live, and wait for Amazon's confirmation before charging real customers.
In Seller Central open Integration Central and create an API key pair. That gives you the four values TourTask needs: the Merchant ID, the Store ID, the Public key ID, and a downloaded private key file (a PEM text file — keep it safe; Amazon cannot re-download it for you). While you are there, add your booking page's web addresses to the allowed domains — the Amazon Pay button refuses to render on a domain Amazon doesn't know about.
In TourTask go to Configuration → Payment options, add Amazon Pay, and pick your country. The currency follows your Amazon Pay region automatically: USD for US merchants, GBP for the UK, JPY for Japan, and EUR for European merchants (including Sweden, Denmark, Switzerland and Hungary — Amazon Pay Europe settles them all in EUR). Paste the Merchant ID, Store ID and Public key ID, paste the private key file's full contents into the private-key field, and press Activate. Customers then get Amazon's own button, finish the payment on Amazon-hosted pages, and the booking confirms when they return.
