MOLPay Payment Gateway For Swift

In this Blog , we are going to learn about how to implement the MOLPay Payment Gateway in your iOS Application. In addition I am explain the method and workflow of the payment Gateway in Swift.

Payment Gateways are use in all the Application in which there is requirement of the Transaction. With the Passage of time now companies are using digital transaction and with their requirement we need to implement the available payment gateway in the Application. In this Blog, we will learn about MOLPay Payment Gateway

Let’s start with the Integration of the payment gateway in your iOS Application. Please follow the steps below for integration.

Step -1

Go to the Link https://docs.adyen.com/payment-methods/molpay and create your account in the MOLPay Platform.

Step – 2

After Creating your Account , login in into your account and generate the test credentials for the Payment gateway.

Step – 3

Now Follow the Below Procedure for the integration of the Payment Gateway in your iOS Application.

Please follow the installation Procedure Below :

Step -A

Please create a Pod file and write the required pod “pod ‘MOLPayXDK'” for the MOLPay payment Gateway.

Step – B

Now import the MOLPay Sdk framework into your iOS Application project.

Step – C

Now go to the ViewController where you want to integrate the payment Gateway in your iOS Application i.e on Checkout View Controller in your iOS Application.

Step – D

Create an instance of the MOLPayLib() in the view Controller Class

var mp = MOLPayLib()

1	var mp = MOLPayLib()

Step – E

Now we call the start molpay Method. Therefore, it will initialise the Payment Gateway SDK.

self.startmolpay()

1	self.startmolpay()

Step – F

In this method we are assign the delegate of the MOLPayLib to viewController and parsing the required field for the Payment gateway.

func startmolpay() {
        self.isPaymentInstructionPresent = false
        self.isCloseButtonClick = false
        let paymentRequestDict: [String:Any] = [
            "mp_amount": amount,
            "mp_username": "api_fashionhub",
            "mp_password": "api_Fas#$%nio",
            "mp_merchant_ID": merchantID,
            "mp_app_name": "fashionhub",
            "mp_order_ID": orderID,
            "mp_currency": currency,
            "mp_country": country,
            "mp_verification_key": verificationKey,
            "mp_channel": channnel,
            "mp_bill_description": billDesc,
            "mp_bill_name": billName,
            "mp_bill_email": billEmail,
            "mp_bill_mobile": billMobile
        ]
        
        print("This is for payment Dict")
        print(paymentRequestDict)
        
        
        self.mp = MOLPayLib(delegate:self, andPaymentDetails: paymentRequestDict)
        self.mp.navigationItem.rightBarButtonItem = UIBarButtonItem(
            title: "Close",
            style: .plain,
            target: self,
            action: #selector(self.closemolpay)
        )
        self.mp.navigationItem.hidesBackButton = true
        
        // Present method (Simple mode)
        let nc = UINavigationController()
        nc.viewControllers = [mp]
        
        self.present(nc, animated: false) {
            print("---presented")
        }
    }

func startmolpay() {

self.isPaymentInstructionPresent = false

self.isCloseButtonClick = false

let paymentRequestDict: [String:Any] = [

"mp_amount": amount,

"mp_username": "api_fashionhub",

"mp_password": "api_Fas#$%nio",

"mp_merchant_ID": merchantID,

"mp_app_name": "fashionhub",

"mp_order_ID": orderID,

"mp_currency": currency,

"mp_country": country,

"mp_verification_key": verificationKey,

"mp_channel": channnel,

"mp_bill_description": billDesc,

"mp_bill_name": billName,

"mp_bill_email": billEmail,

"mp_bill_mobile": billMobile

]

print("This is for payment Dict")

print(paymentRequestDict)

self.mp = MOLPayLib(delegate:self, andPaymentDetails: paymentRequestDict)

self.mp.navigationItem.rightBarButtonItem = UIBarButtonItem(

title: "Close",

style: .plain,

target: self,

action: #selector(self.closemolpay)

)

self.mp.navigationItem.hidesBackButton = true

// Present method (Simple mode)

let nc = UINavigationController()

nc.viewControllers = [mp]

self.present(nc, animated: false) {

print("---presented")

}

Step – G

For instance this is Deep Linking method provided in the demo App by the MOLPay payment Gateway Team. However, for more information on Deep Linking Press here.

@IBAction func deeplinkToVTApp(sender: UIBarButtonItem) {
        
        let application = UIApplication.shared
        
        let razerVTApp = "molpayvt://mp_url_scheme=molpayvt&mp_amount=1.10&mp_merchant_ID=SB_molpayxdk&mp_verification_key=&mp_order_ID=swift-ios&mp_channel=paynow&mp_bill_description=test payment&mp_bill_name=nick&mp_bill_email=nick@email.com&mp_bill_mobile=0111111111"
        guard let razerVTURL = razerVTApp.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) else {return}
        
        guard let appUrl = URL(string: razerVTURL) else {return }
        
        let websiteUrl = URL(string: "https://razer.com")!
        
        if application.canOpenURL(appUrl) {
            application.open(appUrl, options: [:], completionHandler: nil)
        } else {
            print("cannot open molpayvt")
            application.open(websiteUrl, options: [:], completionHandler: nil)
        }
        
        
    }

@IBAction func deeplinkToVTApp(sender: UIBarButtonItem) {

let application = UIApplication.shared

let razerVTApp = "molpayvt://mp_url_scheme=molpayvt&mp_amount=1.10&mp_merchant_ID=SB_molpayxdk&mp_verification_key=&mp_order_ID=swift-ios&mp_channel=paynow&mp_bill_description=test payment&mp_bill_name=nick&mp_bill_email=nick@email.com&mp_bill_mobile=0111111111"

guard let razerVTURL = razerVTApp.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) else {return}

guard let appUrl = URL(string: razerVTURL) else {return }

let websiteUrl = URL(string: "https://razer.com")!

if application.canOpenURL(appUrl) {

application.open(appUrl, options: [:], completionHandler: nil)

} else {

print("cannot open molpayvt")

application.open(websiteUrl, options: [:], completionHandler: nil)

}

Step – H

After that close button this method will trigger

@IBAction func closemolpay(sender: UIBarButtonItem) {
        // Closes MOLPay
        self.mp.closemolpay()
        isCloseButtonClick = true
        print("---Close: \(NSNumber.init(booleanLiteral: true))")
    }

@IBAction func closemolpay(sender: UIBarButtonItem) {

// Closes MOLPay

self.mp.closemolpay()

isCloseButtonClick = true

print("---Close: \(NSNumber.init(booleanLiteral: true))")

}

Step – I

In addition, use this extension with the method of transaction Result

extension CheckoutDataViewController:  MOLPayLibDelegate {
    func transactionResult(_ result: [AnyHashable : Any]!) {
        
        if(result["status_code"] as? String == "11"){
//            if data["status_code"].stringValue == "11" {
            
            // This is for failure
            self.dismiss(animated: true);
        }else if(result["status_code"] as? String == "00"){
            
            // This is for success
            self.dismiss(animated: true);
        }else{
            if(result["pInstruction"] as? NSNumber == 1){
            }else{
                
            }
            // This is for failure
            self.dismiss(animated: true);
            
        }
    }
}

extension CheckoutDataViewController: MOLPayLibDelegate {

func transactionResult(_ result: [AnyHashable : Any]!) {

if(result["status_code"] as? String == "11"){

// if data["status_code"].stringValue == "11" {

// This is for failure

self.dismiss(animated: true);

}else if(result["status_code"] as? String == "00"){

// This is for success

self.dismiss(animated: true);

}else{

if(result["pInstruction"] as? NSNumber == 1){

}else{

}

// This is for failure

self.dismiss(animated: true);

}
