Ayden Payment Gateway In iOS SDK

when Please follow below steps to integrate Ayden Payment Gateway

Adyen Components for iOS allows you to accept in-app payment by providing you with the building blocks you need to create a checkout experience with Adyen.

Installation

Add pod 'Adyen' to your Podfile.
Run pod install.

Drop-in

The Drop-in handles the presentation of available payment methods and the subsequent entry of a customer’s payment details. It is initialized with the response of payment methods and provides everything you need to make an API call to payments and /payments/details.

Usage

Presenting the Drop-in

The Drop-in requires the response of the paymentMethods endpoint to be initialized. To pass the response to Drop-in, and also, decode the response to the payment methods structure:

let paymentMethods = try JSONDecoder().decode(PaymentMethods.self, from: response)

1	let paymentMethods = try JSONDecoder().decode(PaymentMethods.self, from: response)

Some payment methods need an additional configuration also. For example, to enable the card form, the Drop-in needs a public key to use for encryption. This payment method specific configuration parameters can be set in an instance of DropInComponent.PaymentmethodsConfiguration:

let configuration = DropInComponent.PaymentMethodsConfiguration()
configuration.card.publicKey = "..." // Your public key,while retrieved from the Customer Area.

1 2	let configuration = DropInComponent.PaymentMethodsConfiguration() configuration.card.publicKey = "..." // Your public key,while retrieved from the Customer Area.

Assign a delegate and use the viewController property to present the Drop-in on the screen:

let dropInComponent = DropInComponent(paymentMethods: paymentMethods,
paymentMethodsConfiguration: configuration)
dropInComponent.delegate = self
present(dropInComponent.viewController, animated: true)

let dropInComponent = DropInComponent(paymentMethods: paymentMethods,

paymentMethodsConfiguration: configuration)

dropInComponent.delegate = self

present(dropInComponent.viewController, animated: true)

Implementing DropInComponentDelegate

To handle the results of the Drop-in, the following methods of DropInComponentDelegate should be implemented:

func didSubmit(_ data: PaymentComponentData, from component: DropInComponent)

1	func didSubmit(_ data: PaymentComponentData, from component: DropInComponent)

When the customer has selected a payment method and entered its payment details this method is invoked. While the payment details can be read from data.paymentMethod and can be submitted as-is to payments.

func didProvide(_ data: ActionComponentData, from component: DropInComponent)

1	func didProvide(_ data: ActionComponentData, from component: DropInComponent)

This method is invoked when additional details are provided by the Drop-in after the first call to /payments. This happens also, for example, during the 3D Secure 2 authentication flow or any redirect flow. while The additional details can be retrieved from data.details and can be submitted to /payments/details.

func didFail(with error: Error, from component: DropInComponent)

1	func didFail(with error: Error, from component: DropInComponent)

When an error occurred during the use of the Drop-in this method is invoked. Also, dismiss the view controller and display an error message.

let action = try JSONDecoder().decode(Action.self, from: actionData)
dropInComponent.handle(action)

1 2	let action = try JSONDecoder().decode(Action.self, from: actionData) dropInComponent.handle(action)

In case the customer is redirecting to an external URL, make sure to let the Drop-in know when the user returns to your app. but Do this by implementing the following in your UIApplicationDelegate:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool {
    Adyen.applicationDidOpen(url)

    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool {

Adyen.applicationDidOpen(url)

return true

}

Components

In order to have more flexibility over the checkout flow, you can use our Components to present each payment method individually.

Available Components

Card Component
3D Secure 2 Component
Apple Pay Component
BCMC Component
iDEAL Component
SEPA Direct Debit Component
MOLPay Component
Dotpay Component
EPS Component
Entercash Component
Open Banking Component
WeChat Pay Component
Qiwi Wallet Component
Redirect Component

Customization

Both the Drop-in and the Components offer a number of customization options to allow you to match the appearance of your app. For example, to change the section header titles and form field titles in the Drop-in to red, and turn the submit button’s background to blue:

var style = DropInComponent.Style()
style.listComponent.sectionHeader.title.color = .red
style.formComponent.textField.title.color = .red
style.formComponent.footer.button.backgroundColor = .purple

let dropInComponent = DropInComponent(paymentMethods: paymentMethods,
                                      paymentMethodsConfiguration: configuration,
                                      style: style)

var style = DropInComponent.Style()

style.listComponent.sectionHeader.title.color = .red

style.formComponent.textField.title.color = .red

style.formComponent.footer.button.backgroundColor = .purple

let dropInComponent = DropInComponent(paymentMethods: paymentMethods,

paymentMethodsConfiguration: configuration,

style: style)

Or, to create a black Card Component with white text:

var style = FormComponentStyle()
style.backgroundColor = .black
style.header.title.color = .white
style.textField.title.color = .white
style.textField.text.color = .white
style.switch.title.color = .white

let component = CardComponent(paymentMethod: paymentMethod,
                              publicKey: Configuration.cardPublicKey,
                              style: style)

var style = FormComponentStyle()

style.backgroundColor = .black

style.header.title.color = .white

style.textField.title.color = .white

style.textField.text.color = .white

style.switch.title.color = .white

let component = CardComponent(paymentMethod: paymentMethod,

publicKey: Configuration.cardPublicKey,

style: style)
