Razorpay Payment Gateway Integration In iOS Swift

Razorpay Payment Gateway Integration In iOS Swift
Introduction
Razorpay is the fastest growing Payment Solution. Most of the developers prefer Razorpay as the
Payment solution in India. It is robust and provides developer friendly API & SDK for Android, iOS etc. It
provides different modes of payments like :- credit card, debit card, net banking, UPI and other popular
wallets. It provide the fast and reliable support.
In this blog we are going to focus on Razor Pay integration with iOS swift 4 using Xcode 10.1. in which
we will learn how can we integrate Razorpay with iOS app. We will create a demo app to integrate
Razorpay and pay some amount by using Razorpay payment gateway.
Prequisite
1.xcode 10.1
2.Swift 4
3.A Razorpay account (you can signup from here https://dashboard.Razorpay.com/#/access/signup)
4.your Razorpay key id (you can get from here https://dashboard.Razorpay.com/#/app/keys)
Let’s start the development :-
Step 1: Install pod for Razorpay
•Add pod ‘Razorpay-pod’ in the pod file.
•Run ‘pod install’ from terminal.
•Now open the xcworkspace

Step 2: Develop a basic UI as given below.
Step 3: Import Razorpay to your view Controller.
import Razorpay
step 4 :
1.Create action outlet of pay now button in your view controller.
1
2
@IBAction func payNowClicked(_ sender: Any) {
}
2. Create instance reference variable of type Razorpay.
1 private var razorpay:Razorpay?
3. Initialise that reference variable in viewDidLoad method of view controller by calling init method with
public key and delegate.

4
override func viewDidLoad() {
super.viewDidLoad()
razorpay =
Razorpay.initWithKey("rzp_test
_FYCQAsmKTFF8FR",
andDelegate: self)
}
4. Create extension of view controller and confirm RazorpayPaymentCompletionProtocol as given
below :-
a) onPaymentSuccess(_ payment_id: String)
b) onPaymentError(_ code: Int32, description str: String)

extension ViewController: RazorpayPaymentCompletionProtocol {
func onPaymentSuccess(_ payment_id: String) {
let alert = UIAlertController(title: "Paid", message:
"Payment Success", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .cancel,
handler: nil)
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
}
func onPaymentError(_ code: Int32, description str: String)
{
let alert = UIAlertController(title: "Error", message: "
(code)n(str)", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .cancel,
handler: nil)
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
}
}
As you can see in above code we have two methods onPaymentSuccess and onPaymentError the
success method will be called if payment transaction is completed successfully where the
onPaymentError will be called if the transaction is not completed successfully. it provides some error
codes as given below :-
Possible values for a failure code are:
•0: Network error
•1: Initialization failure / Unexpected behavior
•2: Payment cancelled by user
Now inside action outlet of pay button create parameter for razor pay like.

"name": "business or

"prefill": [
"contact":
"9797979797",
"email":
"foo@bar.com"
],
"theme": [
"color": "#F37254"
]
]
Progress Bar:
To support theme color in the progress bar, pass HEX color values only.
after setting all parameters call the open method of Razorpay
1 razorpay?.open(options)
