# Atome iOS Component

Add Atome to your Components integration.

[View source](/payment-methods/atome/ios-component.md)

You can add Atome to your existing integration. The following instructions show only what you must add to your integration specifically for Atome.

If an instruction on this page corresponds with a step in the main integration guide, it includes a link to corresponding step of the main integration guide.

### Add-Configuration

## Add additional configuration for Atome

You do not need to add any configuration parameters for Atome.

### Initialize

## Initialize the Component for Atome

To [initialize](#initialize-the-component) Atome, use the `AtomeComponent` class.

**Initialize the Component**

```swift
let paymentMethods = session.sessionContext.paymentMethods
// Check that the payment method is supported before showing the Component.
guard let paymentMethod = paymentMethods.paymentMethod(ofType: AtomePaymentMethod.self) else { return }
// Create an instance of AtomeComponent.
let component = AtomeComponent(paymentMethod: paymentMethod,
                                        context: context,
                                        // Set the configuration object that you created for Atome.
                                        configuration: atomeConfiguration)
self.currentComponent = component
// Set the session as the delegate.
component.delegate = session
// Present the Component.
let componentViewController = viewController(for: component)
present(componentViewController)
```

### Refunds

## Refunds and cancellations

### Partial refunds

To [partially refund](/online-payments/refund) a payment, specify in your [/payments/{paymentPspReference}/refunds](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/\(paymentPspReference\)/refunds) request:

* [amount](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/\(paymentPspReference\)/refunds#request-amount): The amount to be refunded to the shopper.

## Test and go live

To test Atome payments, you need a test shopper account in the Atome sandbox environment. To request a test account, reach out to your Adyen contact. If you are testing in multiple countries/regions, use a different test account for each location.

To test the QR code flow, download one of the following test apps:

#### For Malaysia (MY)

* [Android app](https://www.pgyer.com/vBsC)
* [iOS app](https://testflight.apple.com/join/SPxKJdnB)

#### For Singapore (SG)

* [Android app](https://www.pgyer.com/m4OL)
* [iOS app](https://testflight.apple.com/join/SPxKJdnB)

You can check the status of test payments in your [Customer Area](https://ca-test.adyen.com/) > **Transactions** > **Payments**.

To accept live Atome payments, you must contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) to add Atome in your live Customer Area.

### Refunds

## Refunds and cancellations

### Partial refunds

To [partially refund](/online-payments/refund) a payment, specify in your [/payments/{paymentPspReference}/refunds](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/\(paymentPspReference\)/refunds) request:

* [amount](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/\(paymentPspReference\)/refunds#request-amount): The amount to be refunded to the shopper.

## Test and go live

To test Atome payments, you need a test shopper account in the Atome sandbox environment. To request a test account, reach out to your Adyen contact. If you are testing in multiple countries/regions, use a different test account for each location.

To test the QR code flow, download one of the following test apps:

#### For Malaysia (MY)

* [Android app](https://www.pgyer.com/vBsC)
* [iOS app](https://testflight.apple.com/join/SPxKJdnB)

#### For Singapore (SG)

* [Android app](https://www.pgyer.com/m4OL)
* [iOS app](https://testflight.apple.com/join/SPxKJdnB)

You can check the status of test payments in your [Customer Area](https://ca-test.adyen.com/) > **Transactions** > **Payments**.

To accept live Atome payments, you must contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) to add Atome in your live Customer Area.
