TipTopPay SDK for Flutter

A Flutter plugin for integrating TipTopPay payments in Android and iOS applications.

Supports

X Check the validity of the card's parameters.
X Generate card cryptogram packet.
X Show 3ds dialog.

Getting Started

Initializing for Android

If you want to show 3ds dialog on Android, make MainActivity implements FlutterFragmentActivity instead of FlutterActivity

android/app/src/main/.../MainActivity.kt:

import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() {}

Usage

Check card number validity.

bool isValid = await TipTopPaySdk.isValidNumber(cardNumber);

Check card expire date.

bool isValid = await TipTopPaySdk.isValidExpireDate(cardNumber); // MM/yy

Generate card cryptogram packet. You need to get your publicId from your personal account and you need apiUrl (for example: https://api.tiptoppay.kz/)

final cryptogram = await TipTopPaySdk.createHexPacketFromData(
  event.cardNumber,
  event.expiryDate,
  event.cvcCode,
  Constants.MERCHANT_PUBLIC_ID,
  Constants.API_URL 
);

Showing 3DS form and get results of 3DS auth.

final result = await TipTopPaySdk.show3ds(
  acsUrl,
  transactionId,
  paReq,
);

Apple Pay

Create instance of TipTopPayApplePay.

final applePay = TipTopPayApplePay();

Check whether Apple Pay is available on this device and can process payment requests.

final isApplePayAvailable = await applePay.isApplePayAvailable();

Request payment.

final paymentToken = await applePay.requestApplePayPayment(
    merchantId: 'merchant.com.YOURDOMAIN',
    currencyCode: 'KZT',
    countryCode: 'KAZ',
    products: [
        {"name": "Red apple", "price": "170"},
        {"name": "Mango", "price": "250.50"},
        {"name": "Delivery", "price": "100"},
        {"name": "Discount", "price": "-89.90"},
        {"name": "Total", "price": "430.60"},
    ],
);

Now you can use paymentToken for payment by a cryptogram.

Google Pay

Create instance of TipTopPayGooglePay. Pass Google Pay Evironemnt (test or production) into constructor.

final googlePay = TipTopPayGooglePay(GooglePayEnvironment.production);

Check whether Google Pay is available on this device and can process payment requests.

final isGooglePayAvailable = await googlePay.isGooglePayAvailable();

Request payment.

final result = await googlePay.requestGooglePayPayment(
    price: '123.45',
    currencyCode: 'KZT',
    countryCode: 'KAZ',
    merchantName: 'Example Merchant',
    publicId: 'test_api_00000000000000000000002',
);

if (result != null) {
    if (result.isSuccess) {
      final paymentToken = result.token;
    }
}
