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 perform tokenized/recurring transactions using this SDK. 


To enable tokenization (for recurring or any other services that depend on auto-detection from the customers instead of saving credit card details), please follow the below instructions:

  1. Request a token in creating any payment request by passing the "tokeniseType" along with the "tokenFormat" with the preferred type and format that suits your business needs within your PaymentSdkConfigurationDetails, as shown below.  
    tokeniseType: PaymentSdkTokeniseType.MERCHANT_MANDATORY,
tokenFormat: PaymentSdkTokenFormat.AlphaNum20Format,


    To know more about these parameters and what are the available values you can pass please check the "2.3 Flutter SDK | Enums" solution article.


  2. Make sure you import PaymentSdkConfigurationDetails class.

  3. 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", 
        "country", 
        "city", 
        "state", 
        "zip code"
);
        
var shippingDetails = new ShippingDetails(
    "shipping name", 
     "shipping email", 
     "shipping phone",
     "address line", 
     "country", 
     "city", 
     "state", 
     "zip code"
);
    Generic


     

  4. 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",
        tokeniseType: PaymentSdkTokeniseType.MERCHANT_MANDATORY,
        tokenFormat: PaymentSdkTokenFormat.AlphaNum20Format
);



  5. Only then you will be ready to start/initiate the payment by passing your PaymentSdkConfigurationDetails object to the startCardPayment 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.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.
        }
      });
    });



  6. After this, you will receive the token along with the transaction reference (that generated this token) within the event callback in which you handled the payment response. You will need to save them for future usage.


  7. Then perform any further recurring transaction according to your business needs by repeating steps 2 and 3 from this solution article, then directly start the tokenized card payment via the startTokenizedCardPayment function by passing the PaymentSdkConfigurationDetails object along with the token and the transaction reference (saved from the previous step).

    FlutterPaytabsBridge.startTokenizedCardPayment(configuration, "Token", "TransactionReference", (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.
        }
      });
    });
