Save a card

The whole integration

// Save the card on the first charge (or POST /tokens to save without charging):
const first = await fetch("https://cygma.cloud/api/m360/v1/payments", {
  method: "POST",
  headers: { Authorization: "Bearer " + SECRET_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({
    amount: 1999,
    card: { number: "4242424242424242", exp_month: 12, exp_year: 30, cvv: "123" },
    save_card: true,
  }),
}).then((r) => r.json());
// first.card_token  ->  "card_…"   (store this; the PAN is gone)

// Charge the saved card later — no card details needed:
await fetch("https://cygma.cloud/api/m360/v1/payments", {
  method: "POST",
  headers: { Authorization: "Bearer " + SECRET_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({ amount: 1999, card_token: first.card_token }),
});
