One-time card checkout

do {
    let result = try await SwirepayAPIHelper.shared.createOneTimeEncryptedCardCheckout(
        customerName: name,
        customerEmail: email,
        phoneE164: "+14155552671",
        cardNumberDigits: "4242424242424242",
        expiryMonth: 12,
        expiryYear: 2030,
        cvv: "123",
        cardholderName: name,
        billingStreet: street,
        billingCity: city,
        billingState: state,
        billingPostalCode: postal,
        billingCountryCode: "US",
        amountMinorUnits: 1000,
        currencyCode: "USD"
    )

    let completion = result.paymentCompletionResponse
    if completion.success {
        // Done — use completion.paymentMethodGid / paymentSessionGid
    }
} catch {
    // Show error.localizedDescription
}

On staging, this auto-creates a checkout session when none is set. For production apps, prefer explicit createCheckoutSession + checkout-session pipeline (same as Checkout sheet).

Recurring card checkout

let result = try await SwirepayAPIHelper.shared.createRecurringEncryptedCardCheckout(
    // same parameters as one-time …
)
// result returns item/plan/subscription gids (separate from one-time completion shape)

Notes

• SwirepayCard.shared.startPayment(amount:) is a sample-only helper that uses a placeholder token. Replace with real tokenization in production.
• Always read completion.success — HTTP 200 alone does not confirm payment.
