More than 1 year has passed since last update.

環境

ドキュメント(Stripe公式)

設定

KEYの設定(環境変数)

こちらを参照。

initializersの設定

こちらを参照。

コンソールでテスト

テスト結果は、stripeのダッシュボードで確認可能。
※ユーザ固有のキーを使っている場合のみ。
※ダッシュボードで 「テストデータを表示」 をチェックすること。

リクエスト例

## customer の作成
customer = Stripe::Customer.create({
    source: 'tok_mastercard',
    email: 'paying.user@example.com',
})

## customer にチャージする (カードではなく)
charge = Stripe::Charge.create({
    amount: 1000,
    currency: 'jpy',
    customer: customer.id,
})

## customer ID (customer.id) や、その他の情報をデータベースに保存する。

## 再度、customer にチャージする際に、↑で保存した customer ID を使う。以下の customer_id はデータベースに保存していたもの。
charge = Stripe::Charge.create({
    amount: 1500,
    currency: 'jpy',
    customer: customer_id,
})
