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(() {
        if (event["status"] == "success") {
          // 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.
        } else if (event["status"] == "event") {
          // Handle events here.
        }

          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.


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

configuration.simplifyApplePayValidation = true;

  1. 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 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
  1. 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 events here.

        }

      });

    });
    

Handling Transaction response

you can use event"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:

UI guide

iOS Theme
