Adyen Checkout is a native client for accepting payments in-app.

AdyenCheckout

Usage

To run the example project, clone the repo and run pod install from the example directory. You can use the library in two ways:

• Plug & Play
• Advanced.

Plug & Play example

Provide the token or public key to the library:

Checkout.shared.publicKey = "YOUR_ADYEN_PUBLIC_KEY"
// OR
Checkout.shared.token = "YOUR_ADYEN_TOKEN"

Show the CheckoutCardViewController to checkout with card:

// Create payment request
let request = CheckoutRequest()
request.amount = 1.99
request.currency = "EUR"
request.reference = "Merchant Reference 123"

// Create Checkout view controller
let vc = CheckoutCardViewController(checkoutRequest: request)
vc.delegate = self
vc.titleText = "My Company"

// Present the controller
let nc = UINavigationController(rootViewController: vc)
self.presentViewController(nc, animated: true, completion: nil)

And implement the CheckoutViewControllerDelegate functions:

func checkoutViewController(controller: CheckoutViewController, authorizedPayment payment: CheckoutPayment) {
    // Dismiss the view controller
    controller.dismissViewControllerAnimated(true, completion: nil)

    // Send the payment to your server which should validate it with Adyen
    sendPayment(payment) { (psp, error) -> Void in
        if (error != nil) {
            let alert = UIAlertView(title: "Error", message: error!.localizedDescription, delegate: nil, cancelButtonTitle: "OK")
            alert.show()
        } else {
            let alert = UIAlertView(title: "Success!", message: "PSP: \(psp)", delegate: nil, cancelButtonTitle: "OK")
            alert.show()
        }
    }
}

func checkoutViewController(controller: CheckoutViewController, failedWithError error: NSError) {
    // Dismiss the view controller
    controller.dismissViewControllerAnimated(true, completion: nil)

    //Show error
    let alert = UIAlertView(title: "Error", message: error.localizedDescription, delegate: nil, cancelButtonTitle: "OK")
    alert.show()
}

The CheckoutPayment contains amount, currency, reference and paymentData which is Base64 encrypted data.

More advanced Usage

Take power with the advance library usage. Display the card fields in your view by adding a separate CardPaymentField , UIView class.

let paymentFieldView = CardPaymentField()
self.view.addSubview(paymentFieldView)

Ensure that you have a valid public key for encryption, or get it with token:

if (Checkout.shared.publicKey == nil) {
    Checkout.shared.fetchPublickKey({ (publicKey, error) -> Void in
        if (error != nil) {
            // Handle error                    
        }
    })
}

Encrypt the obtained data:

if (paymentFieldView.valid) {
    let card = paymentFieldView.paymentData()
    do {
        let paymentData = try card.serialize()
        let payment = CheckoutPayment(request: self.request, encryptedData: paymentData)
        // Send payment to Adyen
    }
    catch let error as NSError {
        // Handle error
    }
}
