PayPal Integration

For a PayPal payment, create a PaymentProcess of type payPalPayment :

let merchantDetails = MerchantDetails.merchant(withID: merchantID, inTest: isTestMerchantID)

let payPalProcess = PaymentProcess.payPalPayment(
    withMerchant: merchantDetails) { [unowned self] callback in
    // Make the registration call and return the callback
}

The SDK offers a declarative API to instantiate a controller for paypal payment with result callbacks for success, cancellation and failure. Present this controller and handle the callbacks accordingly.

PiaSDK.controller(
    for: payPalProcess,
    success: { piaController, transactionId in  },        // Commit the transaction with your merchant backend
    cancellation: { piaController, transactionId in },    // User canceled, rollback the transaction
    failure: { piaController, error in}                   // Rollback transaction, check error object for detail. 
)

The following sample code demonstrates how registration results are returned to the SDK via callback.

fun registerPayPalPayment(piaCallback: (TransactionID, RedirectURL) -> Void) {

    // Make a paypal registration request with your backend to retrieve a transactionID and redirectURL. 

    // Callback with `transactionID` and `redirectURL` obtained from your merchant backend
    callback(.success(withTransactionID: response.transactionId, redirectURL: response.redirectURL))

    // If registration request failed with your backend, callback the SDK with the error. 
    callback(.failure(error))
}

After the transaction has been registered, Netaxept will send back the url for performing the PayPal payment which will be loaded inside a webView. The webView will look like below:

Netaxept backend integration request body - Pay Pal payment registration:

{
    "paymentMethodActionList" : { 
        "PaymentMethod" : "PayPal" 
    }
}
