1. Configure the billing & shipping info, the shipping info is optional

  var billingDetails = new BillingDetails("billing name", 
    "billing email", 
    "billing phone",
        "address line", 
        "country", 
        "city",

var configuration = PaymentSdkConfigurationDetails();
var theme = IOSThemeConfigurations();
theme.logoImage = "assets/logo.png";
configuration.iOSThemeConfigurations = theme;

1-Pay with Card

Start payment by calling startCardPayment method and handle the transaction details

FlutterPaytabsBridge.startCardPayment(configuration, (event) {
      setState(() {

          // Handle transaction details here.
          var transactionDetails = event["data"];
          print(transactionDetails);
          
          if (transactionDetails["isSuccess"]) {
            print("successful transaction");
          } else {
            print("failed transaction");
          }
        } else if (event["status"] == "error") {
          // Handle error here.

Pay with Apple Pay

1. Follow the guide Steps to configure Apple Pay to learn how to configure ApplePay with PayTabs.

2. Do the steps 1 and 2 from Pay with Card although you can ignore Billing & Shipping details and Apple Pay will handle it, also you must pass the merchant name and merchant identifier.

//ignore this part if you want to use default networks
 List<PaymentSDKNetworks> networks = [];
    networks.add(PaymentSDKNetworks.visa);
    networks.add(PaymentSDKNetworks.amex);

 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",
        locale: PaymentSdkLocale.AR, //PaymentSdkLocale.EN or PaymentSdkLocale.DEFAULT 
        amount: "amount in double",
        currencyCode: "Currency code",
        merchantCountryCode: "2 chars iso country code",
        merchantApplePayIndentifier: "merchant.com.bundleID",
        linkBillingNameWithCardHolderName: true,
    paymentNetworks: networks);

3. To simplify ApplePay validation on all user's billing info, pass simplifyApplePayValidation parameter in the configuration with true.

configuration.simplifyApplePayValidation = true;

4. Call startApplePayPayment to start payment

FlutterPaytabsBridge.startApplePayPayment(configuration, (event) {
      setState(() {
        setState(() {
        if (event["status"] == "success") {
          // Handle transaction details here.
          var transactionDetails = event["data"];
          print(transactionDetails);
        } else if (event["status"] == "error") {
          // Handle error here.
        } else if (event["status"] == "event") {
          // Handle cancel events here.
        }
      });
      });
    });

Pay with Samsung Pay

Pass Samsung Pay token to the configuration and call startSamsungPayPayment

configuration.samsungToken = "{Json token returned from the samsung pay payment}"

Pay with Alternative Payment Methods

It becomes easy to integrate with other payment methods in your region like STCPay, OmanNet, KNet, Valu, Fawry, UnionPay, and Meeza, to serve a large sector of customers.

1. Do the steps 1 and 2 from Pay with Card
2. Choose one or more of the payment methods you want to support, check the available APMs in the enum section.

 List<PaymentSdkAPms> apms = [];
 apms.add(PaymentSdkAPms.STC_PAY);
 
 var configuration = PaymentSdkConfigurationDetails(
     * Your configuration *
     alternativePaymentMethods: apms); // add the Payment Methods here

3. Call startAlternativePaymentMethod to start payment

FlutterPaytabsBridge.startAlternativePaymentMethod(await generateConfig(),

        (event) {

      setState(() {

        if (event["status"] == "success") {

          // Handle transaction details here.

          var transactionDetails = event["data"];

          print(transactionDetails);

        } else if (event["status"] == "error") {

          // Handle error here.

        } else if (event["status"] == "event") {

          // Handle cancel events here.

        }

      });

    });
    

Discounts

You can add discounts to the payment by passing the discount amount and the discount type to the configuration.

 configuration.cardDiscounts = [
      PaymentSDKCardDiscount(
          discountCards: ["4111"],
          discountValue: 50,
          discountTitle: "50% discount on cards starting with 4111",
          isPercentage: true),
      PaymentSDKCardDiscount(
          discountCards: ["4000", "41111"],
          discountValue: 2,
          discountTitle: "2 EGP discount on cards starting with 4000 and 41111",
          isPercentage: false)
    ];

Card Approval

You can customize BIN-based discounts through the PaymentSDKCardApproval class, which collects approval details via an API.

final cardApproval = PaymentSDKCardApproval(
  validationUrl: "https://webhook.site/f80622ae-a0c0-4664-861e-b71ab1b72d90",
  binLength: 8,
  blockIfNoResponse: false
);

final configuration = PaymentSdkConfigurationDetails(
  ...,
  cardApproval: cardApproval
);

• validationUrl: The endpoint provided by the business to validate the transaction.
• binLength: BIN length (default is 6, can be set to 8).
• blockIfNoResponse: Determines if the transaction should proceed in case of no response from the validation endpoint.

Clear saved cards

You can clear the saved cards using the following method call.

FlutterPaytabsBridge.clearSavedCards()

Query transaction

You can check the status of a transaction

1- first create PaymentSDKQueryConfiguration

var queryConfig = PaymentSDKQueryConfiguration(
    "ServerKey",
    "ClientKey",
    "Country Iso 2",
    "Profile Id",
    "Transaction Reference"
);

2- Call QuerySdkActivity.queryTransaction and pass the needed arguments

FlutterPaytabsBridge.queryTransaction(
    generateConfig(), queryConfig,
    (event) {
        setState(() {
            if (event["status"] == "success") {
                // Handle transaction details here.
                var transactionDetails = event["data"];
                print(transactionDetails);
            } else if (event["status"] == "error") {
                // Handle error here.
            } else if (event["status"] == "event") {
                // Handle cancel events here.
            }
        });
    });

Handling Transaction response

you can use event["data"]["isSuccess"] to ensure a successful transaction ..

if the transaction is not successful you should check for the corresponding failure code you will receive the code in responseCode .. all codes can be found in Payment Response Codes

Link billing name with card holder name

By default, the billing name is linked with card holder name, if you set its flag to false the billing name and the card holder name will be seperated

 var configuration = PaymentSdkConfigurationDetails(
        ...
        ...
        linkBillingNameWithCardHolderName: true
        );

Customize the Theme:

iOS Theme

Use the following guide to cusomize the colors, font, and logo by configuring the theme and pass it to the payment configuration.

	var theme = IOSThemeConfigurations();
	theme.backgroundColor = "e0556e"; // Color hex value
	theme.backgroundColorDark = "520f3a"; // Dark Mode Color hex value
	configuration.iOSThemeConfigurations = theme;

Android Theme

Use the following guide to customize the colors, font, and logo by configuring the theme and pass it to the payment configuration.
