PayTabs SDK makes the integration with the PayTabs payment gateway very easy by providing a ready-made payment screen that handles the card entry and, billing & shipping information and completes the missing details.

This article is dedicated to walking you through how to initiate the payment/request payload using the configuration options and parameters that have already been clarified in the previous step, "Step 2 - Configure the integration method".

After making sure of configuring this SDK as you wish, you will need to import the SDK package classes in your code first to start, as shown below: 

import 'package:flutter_paytabs_bridge/BaseBillingShippingInfo.dart';
import 'package:flutter_paytabs_bridge/PaymentSdkConfigurationDetails.dart';
import 'package:flutter_paytabs_bridge/PaymentSdkLocale.dart';
import 'package:flutter_paytabs_bridge/PaymentSdkTokenFormat.dart';
import 'package:flutter_paytabs_bridge/PaymentSdkTokeniseType.dart';
import 'package:flutter_paytabs_bridge/flutter_paytabs_bridge.dart';
import 'package:flutter_paytabs_bridge/IOSThemeConfiguration.dart';
import 'package:flutter_paytabs_bridge/PaymentSdkTransactionClass.dart';

Implementing this option will enable you to initiate payments targeted to be paid using the supported types of credit cards such as Visa, MasterCard, Amex, .. etc. Furthermore, your SDK will save the card on your behalf to show it in a list of saved cards for any further payments. To be able to do this, please follow the below instructions: 

  1. Make sure you import PaymentSdkConfigurationDetails class.

  2. Configure the billing & shipping information for this payment, noting that the shipping information is optional. To know more about this, please check our 3.1 Flutter SDK | Manage Shipping and Billing details and 2.1 Flutter SDK | Configuration Options & Parameters solution articles. 
    var billingDetails = new BillingDetails(
        "billing name", 
        "billing email", 
        "billing phone",
            "address line", 
            "zip code"
    var shippingDetails = new ShippingDetails(
        "shipping name", 
         "shipping email", 
         "shipping phone",
         "address line", 
         "zip code"

  3. Then create an object from PaymentSdkConfigurationDetails and fill it out with your credentials and payment details. To know more about what is the exact values that should be passed here, please check our 2.1 Flutter SDK | Configuration Options & Parameters and 2.2 Flutter SDK | The PaymentSdkConfigurationDetails Object solution articles.
     var configuration = PaymentSdkConfigurationDetails(
            profileId: "profile id",
            serverKey: "your server key",
            clientKey: "your client key",
            cartId: "cart id",
            cartDescription: "cart desc",
            merchantName: "merchant name",
            screentTitle: "Pay with Card",
            billingDetails: billingDetails,
            shippingDetails: shippingDetails,
            locale: PaymentSdkLocale.EN, //PaymentSdkLocale.AR or PaymentSdkLocale.DEFAULT 
            amount: "amount in double",
            currencyCode: "Currency code",
            merchantCountryCode: "2 chars iso country code"

  4. Only then you will be ready to start/initiate the payment with the previously saved card by passing your PaymentSdkConfigurationDetails object to the startPaymentWithSavedCards function in which the callback event will handle/alter the payment response. To know more about this please check our 2.2 Flutter SDK | The PaymentSdkConfigurationDetails Object and Step 5 - Flutter SDK | Handle the payment response solution articles.
    FlutterPaytabsBridge.startPaymentWithSavedCards(configuration, support3DsBoolean, (event) {
          setState(() {
            if (event["status"] == "success") {
              // Handle transaction details here.
              var transactionDetails = event["data"];
              if (transactionDetails["isSuccess"]) {
                print("successful transaction");
              } else {
                print("failed transaction");
            } else if (event["status"] == "error") {
              // Handle error here.
            } else if (event["status"] == "event") {
              // Handle events here.

    Only cards that has been saved through this startPaymentWithSavedCards function will be shown in the list.

    This would make the payment behavior like the one below, in which once your customers choose one of the saved cards, the payment will be performed directly if the support3DsBoolean was false or will be directed to the 3DS phase if it is true.
