🔐 Secure JWT Flow

You must pass a signed JWT to data prop containing transaction info. Sign this on your server.

---

🔐 Secure Payment Flow with JWT

You must generate a signed JWT on your backend and pass it to the SDK via the data prop.

Example Card Payment Payload:

{
  "id": "ORDER-001",
  "total": 5000,
  "subtotal": 5000,
  "description": "This is an order from the sdk",
  "tax": 0,
  "currency": "JMD",
  "fees": [],
  "items": [],
  "fulfilled": true,
  "shippingPerson": {
    "name": "Shamir Saddler",
    "street": "1 Test Ave",
    "city": "Kingston 6",
    "stateOrProvinceName": "Kingston",
    "postalCode": "00000",
    "countryName": "Jamaica"
  },
  "billingPerson": {
    "name": "Shamir Saddler",
    "street": "1 Test Ave",
    "city": "Kingston 6",
    "stateOrProvinceName": "Kingston",
    "postalCode": "00000",
    "countryName": "Jamaica"
  },
  "webhookUrl": "https://yourservice.com/webhook"
}

Example Card Save Payload:

{
  "webhookUrl": "https://webhook.com",
  "card_request_token": "<card_request_token>",
}

Use a backend library like jsonwebtoken to sign the payload with your secret key. Never expose your secret key in your app.
