コールバック(Webhook)

On every invoice status change we POST the invoice to its callback_url (or the store's Status URL). Withdrawals made with your API key are reported to the Status URL too, when they are sent, completed, fail or are cancelled. Add ?json=true to the URL to get JSON instead of a form post.

  • Answer with HTTP 200. Anything else is retried 8 more times over about two days, then shown as Failed in your dashboard.
  • Always check verify_hash before trusting a callback.
  • Stores & API → Webhooks shows every attempt, lets you resend one, and sends a signed test.

署名の検証

verify_hash is an HMAC-SHA1 with your store's secret key: of PHP's serialize() of the key-sorted fields for form posts, or of JSON.stringify of the body without verify_hash for JSON.

PHP (form post)
<?php
// Your store's secret key (Stores & API → API)
$secretKey = getenv('AYWAPAY_SECRET_KEY');

$post = $_POST;                       // form-encoded callback
$received = $post['verify_hash'] ?? '';
unset($post['verify_hash']);
ksort($post);
$expected = hash_hmac('sha1', serialize($post), $secretKey);

if (!hash_equals($expected, $received)) {
    http_response_code(400);
    exit('bad signature');
}
if ($post['status'] === 'completed' || $post['status'] === 'mismatch') {
    // mark order $post['order_number'] as paid
}
http_response_code(200);
Node.js (JSON)
import crypto from "node:crypto";

// callback_url ends with ?json=true, so the body is JSON
app.post("/callback", express.json(), (req, res) => {
  const { verify_hash, ...body } = req.body;
  const expected = crypto
    .createHmac("sha1", process.env.AYWAPAY_SECRET_KEY)
    .update(JSON.stringify(body))
    .digest("hex");
  const given = Buffer.from(String(verify_hash ?? ""));
  const wanted = Buffer.from(expected);
  if (given.length !== wanted.length || !crypto.timingSafeEqual(given, wanted)) {
    return res.status(400).send("bad signature");
  }

  if (body.status === "completed" || body.status === "mismatch") {
    // mark order body.order_number as paid
  }
  res.sendStatus(200);
});

テストモード(サンドボックス)

Every store can have a test key next to its live key (Stores & API → API → Test key). It works with the same endpoints, with no real money:

  • Invoices made with the test key are test invoices: no deposit address, nothing on a blockchain.
  • Their payment page has Simulate buttons: paid, overpaid, underpaid, expire. Each fires your normal callback, with test=true and signed with the test key.
  • Test invoices never touch your balance. Withdrawals and deposit addresses need the live key (error 229); balances read 0.
  • Order numbers are separate: a test order never blocks a live one with the same number.
Create a test invoice
curl -G "https://api.aywapay.com/api/v1/invoices/new" \
  -d source_currency=USD -d source_amount=10 \
  -d order_number=test-1 -d order_name=Test \
  -d api_key=$AYWAPAY_TEST_KEY

独自の支払いドメイン(ホワイトラベル)

ホワイトラベルプランでは、請求書、支払いリンク、寄付ページ、支払いボタンを当社のアドレスではなく、pay.yourshop.com のような独自のアドレスで開けます。顧客にはあなたのドメインとブランドだけが表示されます。必要なのはDNSレコード1件と約10分だけで、開発者は不要です。

設定方法

  1. ストアをホワイトラベルプランに切り替えます(ストア → 一般)。
  2. ストアの「支払いページ」タブを開き、「支払いリンクを開く場所」で「独自ドメイン」を選びます。
  3. 所有しているサブドメイン(例:pay.yourshop.com)を入力します(yourshop.com そのものは使えません)。手数料が表示された場合は内容を確認してから保存します。
  4. 画面に表示されたレコードをコピーし、ドメインのDNSを管理しているところ(Cloudflare、GoDaddy、Namecheap、Hostinger など)に追加します。ダッシュボードにはそれぞれの簡単なガイドがあります。
  5. あとは待つだけです。1分ごとに確認します:DNS → HTTPS証明書 → 公開中。通常5〜30分ほどですが、新しいDNSレコードは数時間かかることもあります。公開されたらメールでお知らせします。

DNSレコード

タイプ名前値
CNAMEpay<your-code>.domains.aywapay.com

正確なターゲットはダッシュボードからコピーしてください。ストアごとに異なります。多くのプロバイダーでは、名前には最初の部分(pay)だけを入力します。

Cloudflare をお使いの場合

レコードを「DNS only」(グレーの雲)に設定してください。オレンジの雲がオンのままだと証明書を発行できず、確認画面に「プロキシ経由」と表示されます。

確認が通らない場合

  • レコードが見つからない:CNAMEがまだ追加されていないか、DNSがまだ反映されていません。名前を確認して数分お待ちください。
  • 別の場所を指している:同じ名前を別のレコード(A、AAAA、古いCNAME)が使っています。それを削除し、CNAMEだけを残してください。
  • プロキシ経由:Cloudflare のオレンジの雲がオンになっています。レコードを「DNS only」に切り替えてください。
  • 証明書の発行待ち:DNSは正しく設定されています。HTTPS証明書は通常数分で発行されます。

公開後

  • 新しいリンクも既存のリンクも、あなたのドメインで開きます。当社のアドレスで送信済みのリンクも引き続き使えます。
  • いつでもワンクリックで AywaPay のリンクに戻せます。ドメインは保存されたままです。
  • DNSが24時間当社を指さなくなった場合、リンクは自動的に当社のアドレスに戻り、メールでお知らせします。支払いが失われることはありません。
  • アカウントに独自ドメインの手数料が設定されている場合は、保存前に表示され、残高から差し引かれます。
