Stripe Payment Gateway in Swift using SDK

In this blog, we will know about the implementation of the Stripe payment gateway.

And you will receive the payment online from the customer using this payment gateway

1. Need to install the pod for this payment gateway by using the below pod you can access the library of stripe payment.

pod 'Stripe'

1	pod 'Stripe'

2. After installing the pod please import the its library where you want to use payment.

import Stripe

1	import Stripe

3. Initiate the payment in your controller and create a storyboard,

you need to add class STPPaymentCardTextField of the text field then you can able to use its funtionality

If you want to use zip field then use or remove the zip code using the below code

cardTextField.postalCodeEntryEnabled = false

1	cardTextField.postalCodeEntryEnabled = false

Stripe.setDefaultPublishableKey(testPublishableKey ?? "")

 var paymentIntentClientSecret: String?

 @IBOutlet weak var cardTextField: STPPaymentCardTextField!
@IBOutlet weak var payBtn: UIButton!

Stripe.setDefaultPublishableKey(testPublishableKey ?? "")

var paymentIntentClientSecret: String?

@IBOutlet weak var cardTextField: STPPaymentCardTextField!

@IBOutlet weak var payBtn: UIButton!

4. After filled the card and on the pay action you need to call the stripe methods to make payment

 guard let paymentIntentClientSecret = paymentIntentClientSecret else {
            return;
        } 
let cardParams = cardTextField.cardParams
        let paymentMethodParams = STPPaymentMethodParams(card: cardParams, billingDetails: nil, metadata: nil)
        let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret)
        paymentIntentParams.paymentMethodParams = paymentMethodParams
        
        // Submit the payment
        let paymentHandler = STPPaymentHandler.shared()
        paymentHandler.confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { (status, paymentIntent, error) in
            switch (status) {
            case .failed:
                print("Payment failed")
                print(error)
               
                break
            case .canceled:
                print("Payment canceled")
               
                break
            case .succeeded:
                print("Payment succeeded")
                
                break
            @unknown default:
                fatalError()
                break
            }

guard let paymentIntentClientSecret = paymentIntentClientSecret else {

return;

}

let cardParams = cardTextField.cardParams

let paymentMethodParams = STPPaymentMethodParams(card: cardParams, billingDetails: nil, metadata: nil)

let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret)

paymentIntentParams.paymentMethodParams = paymentMethodParams

// Submit the payment

let paymentHandler = STPPaymentHandler.shared()

paymentHandler.confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { (status, paymentIntent, error) in

switch (status) {

case .failed:

print("Payment failed")

print(error)

break

case .canceled:

print("Payment canceled")

break

case .succeeded:

print("Payment succeeded")

break

@unknown default:

fatalError()

break

}

And then please handle the response from the payment gateway and perform an action after success or failure.

Now you can execute the above code and you can receive payment through Stripe payment gateway
