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".

Implementing this option will enable you to initiate payments targeted to be paid using other payment methods that are available in your regions, like STCPay, OmanNet, KNet, Valu, UnionPay, and Meeza, to serve a large sector of customers. To be able to do this, please follow the below instructions:

iOS
Android

iOS:

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:

using PaymentSDKBinding;

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 Xamarin SDK | Manage Shipping and Billing details and 2.1 Xamarin SDK | Configuration Options & Parameters solution articles.

PaymentBillingDetails billingDetails = new PaymentBillingDetails
        {
            Name = "FirstName LastName",
            Email = "[email protected]",
            Phone = "+971111111111",
            AddressLine = "Address line",
            City = "Dubai",
            State = "Dubai",
            CountryCode = "AE",  // ISO alpha 2
            Zip = "12345"
        };

PaymentShippingDetails shippingDetails = new PaymentShippingDetails
        {
            Name = "FirstName LastName",
            Email = "[email protected]",
            Phone = "+971111111111",
            AddressLine = "Address line",
            City = "Dubai",
            State = "Dubai",
            CountryCode = "AE",  // ISO alpha 2
            Zip = "12345"
        };

Then create an object from PaymentConfiguration and fill it out with your credentials and payment details also you need to pass the "AlternativePaymentMethods" parameter list. To know more about what is the exact values that should be passed here, please check our 2.1 Xamarin SDK | Configuration Options & Parameters and 2.2 Xamarin SDK | The Payment Configuration Object solution articles, Also for all available alternative payment methods please check 2.3 Xamarin SDK | Enums solution articles.

PaymentConfiguration configuration = new PaymentConfiguration
{
            ProfileID = "*Profile Id*",
            ServerKey = "*Server key*",
            ClientKey = "*Client Key*",
            MerchantCountryCode = "AE",
            Currency = "USD",
            Amount = 130,
            CartID = "123456",
            CartDescription = "Buy 2 Flowers",
            MerchantName = "Flowers Store",
            ScreenTitle = "Pay with Card",
           AlternativePaymentMethods = new string[] { AlternativePaymentMethod.StcPay, ... };
};

Only then you will be ready to start/initiate the payment by passing your PaymentConfiguration to the StartAlternativePaymentMehtodWithConfiguration method in which the callback event and the setState method will handle/alter the payment response. To know more about this please check our 2.2 Xamarin SDK | The Payment Configuration Object and Step 5 - Xamarin SDK | Handle the payment response solution articles.
```
_proxy.StartAlternativePaymentMehtodWithConfiguration(configuration, this);     
```

Android:

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:

using Com.Payment.Paymentsdk.Integrationmodels;
using Com.Payment.Paymentsdk;
using Com.Payment.Paymentsdk.Sharedclasses.Interfaces;

PaymentBillingDetails billingDetails = new PaymentSdkBillingDetails(
	"Dubai",  //city
	"AE", //2 digit iso Country code
	"[email protected]", //email
	"FirstName LastName", //Full Name
	"+971111111111", // Phone number
	"Dubai", //State
	"address street", // Address Line
	"12345" // ZIP code
);

PaymentSdkShippingDetails shippingDetails = new PaymentSdkShippingDetails(
	"Dubai", //city
	"AE", //2 digit iso Country code
	"[email protected]",  //email
	"FirstName LastName",  //Full Name
	"+971111111111",   // Phone number
	"Dubai", //State
	"Address line",  // Address Line
	"12345"  // ZIP code
);

Then create an object from PaymentSdkConfigBuilder and fill it out with your credentials and payment details also you need to pass the "AlternativePaymentMethods" parameter list. To know more about what is the exact values that should be passed here, please check our 2.1 Xamarin SDK | Configuration Options & Parameters and 2.2 Xamarin SDK | The Payment Configuration Object solution articles.

IList<PaymentSdkApms> apms = new List<PaymentSdkApms>();
apms.Add(PaymentSdkApms.StcPay);
            
PaymentSdkConfigurationDetails configuration = new PaymentSdkConfigBuilder(
"*Profile ID*", "*Server Key*", "*Client Key*", 44.0, "USD")
                .SetCartId("123")
                .SetCartDescription("yyif")
                .SetMerchantCountryCode("AE")
                .SetBillingData(billDetails)
                .SetShippingData(shippingDetails)
                .Build();

configuration.AlternativePaymentMethods = apms;

Only then you will be ready to start/initiate the payment by passing your PaymentConfiguration to the StartAlternativePaymentMethods method in which the callback event and the setState method will handle/alter the payment response. To know more about this please check our 2.2 Xamarin SDK | The Payment Configuration Object and Step 5 - Xamarin SDK | Handle the payment response solution articles.
```
PaymentSdkActivity.StartAlternativePaymentMethods(this, configuration, this); 
```
