Paymob Payment Gateway in Swift

Today, we are going to learn how to integrate Paymob Payment Gateway in Swift with the SDK approach.

Before, implementing the payment gateway first we will learn what is a payment gateway?

A payment gateway is a technique used by merchants to accept credit or debit card purchases from customers.

Paymob provides a list of payment methods.

Card payment
Kiosk Payments
Mobile Wallets
Bank Installments
SOUHOOLA Payments

Many others

Let’s start the integration

Please follow the below steps in your iOS project

Step -1:-

Please install the paymob pod in your project

AcceptCardSDK is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'AcceptCardSDK'

1	pod 'AcceptCardSDK'

After that change the general settings of the project, under libraries and frameworks “Do not embed” to “Embed and Sign”

Step -2:-

Now, import the AcceptSDK in viewcontroller

import AcceptSDK

1	import AcceptSDK

Step -3:-

Create payment

We need a valid payment key is required to start the payment

let accept = AcceptSDK()
            let KEY: String = authKey
            accept.delegate = self
            
            do {
                try accept.presentPayVC(vC: self, paymentKey: KEY, saveCardDefault:
                                            true, showSaveCard: true, showAlerts: true)
            } catch AcceptSDKError.MissingArgumentError(let error_Message) {
                print(error_Message)
            }  catch let error {
                print(error.localizedDescription)
            }

let accept = AcceptSDK()

let KEY: String = authKey

accept.delegate = self

do {

try accept.presentPayVC(vC: self, paymentKey: KEY, saveCardDefault:

true, showSaveCard: true, showAlerts: true)

} catch AcceptSDKError.MissingArgumentError(let error_Message) {

print(error_Message)

} catch let error {

print(error.localizedDescription)

}

Step – 4:-

Add the delegate to the class, and add the protocol stubs

//MARK:- AcceptSDKDelegate

class ViewController: UIViewController, AcceptSDKDelegate {
 func userDidCancel() {
        
    }
    
    func paymentAttemptFailed(_ error: AcceptSDKError, detailedDescription: String) {
    
    }
    
    func transactionRejected(_ payData: PayResponse) {
   
    }
    
    func transactionAccepted(_ payData: PayResponse) {
    
    }
    
    func transactionAccepted(_ payData: PayResponse, savedCardData: SaveCardResponse) {
     
    }
    
    func userDidCancel3dSecurePayment(_ pendingPayData: PayResponse) {
     
    }
}

//MARK:- AcceptSDKDelegate

class ViewController: UIViewController, AcceptSDKDelegate {

func userDidCancel() {

}

func paymentAttemptFailed(_ error: AcceptSDKError, detailedDescription: String) {

}

func transactionRejected(_ payData: PayResponse) {

}

func transactionAccepted(_ payData: PayResponse) {

}

func transactionAccepted(_ payData: PayResponse, savedCardData: SaveCardResponse) {

}

func userDidCancel3dSecurePayment(_ pendingPayData: PayResponse) {

}

And if you already have a saved token

do {
            try accept.presentPayVC(vC: self, paymentKey: KEY,  saveCardDefault: false, showSaveCard: false, showAlerts: true, token: "", maskedPanNumber: "xxxx-xxxx-xxxx-1234")
        } catch AcceptSDKError.MissingArgumentError(let error_Message) {
            print(error_Message)
        } catch let error {
            print(error.localizedDescription)
        }

do {

try accept.presentPayVC(vC: self, paymentKey: KEY, saveCardDefault: false, showSaveCard: false, showAlerts: true, token: "", maskedPanNumber: "xxxx-xxxx-xxxx-1234")

} catch AcceptSDKError.MissingArgumentError(let error_Message) {

print(error_Message)

} catch let error {

print(error.localizedDescription)

}
