認証

すべてのAPIリクエストにはHTTPヘッダーによるHMAC-SHA256認証が必要です。ダッシュボード → ストアで認証情報を取得。

必須ヘッダー

署名の例

payload = "1700000000" + "POST" + "/api/v1/payment/create" + '{"amount":"100"}'
signature = HMAC-SHA256(payload, api_secret)

署名検証 (PHP)

$timestamp = $_SERVER['HTTP_X_TIMESTAMP'];
$signature = $_SERVER['HTTP_X_SIGNATURE'];
$body = file_get_contents('php://input');

$expected = hash_hmac('sha256', $timestamp . $body, $webhookSecret);

if (!hash_equals($expected, $signature)) {
    http_response_code(401);
    die('Invalid signature');
}

$payload = json_decode($body, true);
// Process payment...

JavaScriptウィジェット

決済ウィジェットを埋め込み。HTML + JSのみ。

クイックスタート

<script src="https://soko.ai/widget.js"></script>
<script>
CryptoMerchant.init({ apiKey: 'YOUR_STORE_API_KEY' });

document.getElementById('pay-btn').addEventListener('click', function() {
    CryptoMerchant.pay({
        amount: 100.00,
        order_id: 'ORDER-123',

        // Or use fiat conversion:
        // fiat_amount: 5000,
        // fiat_currency: 'RUB',

        onSuccess: function(payment) {
            alert('Payment confirmed! TX: ' + payment.tx_hash);
        },
        onClose: function() {
            console.log('Widget closed');
        },
        onError: function(err) {
            console.error('Payment error:', err);
        }
    });
});

❤️ 寄付ウィジェット

あらゆるWebサイトで暗号通貨の寄付を受け付けます。API署名不要 — ストアAPIキーのみ。

仕組み

ストア設定で寄付を有効にし、Webサイトにウィジェットを追加します。訪問者はUSDT、BTC、ETHで寄付できます。各寄付は追跡可能な支払いとして作成され、ダッシュボードの❤️ 寄付で確認できます。

クイックスタート — ボタン

スクリプトの位置に「寄付」ボタンを追加:

<script src="https://soko.ai/donate-widget.js"
        data-store-key="YOUR_STORE_API_KEY"></script>

トップバー

ページ上部に固定の寄付バーを表示:

<script src="https://soko.ai/donate-widget.js"
        data-store-key="YOUR_STORE_API_KEY"
        data-mode="topbar"></script>

インライン

指定した要素内にボタンをレンダリング:

<div id="crypto-donate"></div>
<script src="https://soko.ai/donate-widget.js"
        data-store-key="YOUR_STORE_API_KEY"
        data-mode="inline"
        data-target="crypto-donate"></script>

カスタマイズ属性

直接寄付ページ

ウィジェットなしで寄付ページに直接リンクすることもできます:

https://soko.ai/donate/YOUR_STORE_API_KEY
