Drop-in also redirects the shopper to perform the 3D Secure 2 authentication. When making a card payment with redirect 3D Secure 2 authentication, you additionally need to: 1. [Configure Drop-in](#configure-drop-in) to collect the card holder name. 2. [Provide the required 3D Secure parameters](#make-a-payment) when making a payment request. 3. [Handle the redirect result](#handle-the-redirect-result) after the shopper returns to your website. ## Requirements This page explains how to add cards with redirect 3D Secure authentication to your existing iOS Drop-in integration. The iOS Drop-in integration works the same way for all payment methods. If you haven't done this integration yet, refer to our [Drop-in integration guide](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in). Before starting your integration: 1. Make sure that you have [set up your back end implementation](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in), and [added Drop-in to your payment form](/online-payments/build-your-integration/sessions-flow/?platform=iOS\&integration=Drop-in#step-3-set-up-drop-in). 2. [Add the cards that you want to accept in your test Customer Area](/payment-methods/add-payment-methods). 3. If you are using 3D Secure for PSD2 compliance, read our [comprehensive PSD2 SCA guide](/online-payments/psd2-sca-compliance-and-implementation-guide). ## Collect additional parameters in your payment form For higher authentication rates, we strongly recommend that you collect the shopper card holder name and billing address in advance in your payment form. Deliver these parameters to your backend when [making a payment](#make-a-payment), because they are required by the card schemes. ## Show the available cards in your payment form For information about the supported countries/regions and currencies for each card, refer to [Payment methods](https://www.adyen.com/payment-methods). To show cards in your payment form: 1. Specify in your [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) request a combination of [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) and [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount). Drop-in uses this information to show the available cards to your shopper. 2. []()When [initializing the Drop-in](/online-payments/build-your-integration/sessions-flow/?platform=iOS\&integration=Drop-in#step-3-set-up-drop-in), create a configuration object, and specify: * `configuration.card.showsHolderNameField`: **true**. This shows the input field for the cardholder name. To get your public key: 1. Sign in to your [Customer Area](https://ca-test.adyen.com/) using your company account. 2. Navigate to **Developers** > **API credentials**. 3. Click on your web service user (**ws\@Company.\[YourCompanyAccount]**) in the users list.\ This opens the **Edit Web Service User** page. 4. In the **Client-Side Encryption** panel, copy the **Client Encryption Public Key**. ```swift let configuration = DropInComponent.Configuration(apiContext: apiContext) configuration.card.showsHolderNameField = true // Shows the field for entering the holder name. ``` When the shopper is entering their card details, Drop-in tries to recognize the card brand. When successful, Drop-in renders the brand icon. ## Make a payment When the shopper proceeds to pay, Drop-in invokes the `didSubmit` method which contains `data.paymentMethod`. 1. Pass `data.paymentMethod` to your server. 2. When you [make a payment request](/online-payments/build-your-integration/advanced-flow?platform=iOS\&integration=Drop-in\&version=latest#make-a-payment), include the following additional 3D Secure 2 parameters. See additional 3D Secure 2 parameters that we recommend to include in your request to increase authentication performance in our [API reference](/online-payments/3d-secure/api-reference). | Parameter name | Required | Description | | ------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [paymentMethod](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#request-paymentMethod) | ![Required](/user/pages/reuse/image-library/01.icons/required/required.svg?decoding=auto\&fetchpriority=auto) | The type and required details for a card payment method.

[Handle the redirect result](#handle-the-redirect-result). | A sample [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response with `action.type`: **redirect**: **/payments response** ```json { "resultCode":"RedirectShopper", "action":{ "method":"GET", "paymentMethodType":"scheme", "type":"redirect", "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/threeDS/redirect?MD=M2R..." } ... } ``` ## Handle the redirect result Drop-in uses [`dropInComponent.handle(action)` ](https://adyen.github.io/adyen-ios/5.0.0/documentation/adyen/)to redirect the shopper to complete the 3D Secure authentication. 1. To inform Drop-in when the shopper returns to your app, implement the following in your `UIApplicationDelegate`: ```swift func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool { RedirectComponent.applicationDidOpen(from: url) return true } ``` After Drop-in completes the action, it invokes the `didProvide` method. 2. From your server, make a POST [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request providing the `data` from the `didProvide` method from your client app. On Checkout API v67 and later, the payment is authorized after the shopper completes authentication. You make a [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request to get the payment result. On earlier versions, you need to complete the payment by making a [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request containing payment data. #### curl ```bash curl https://checkout-test.adyen.com/v72/payments/details \ -H 'x-api-key: ADYEN_API_KEY' \ -H 'content-type: application/json' \ -d '{hint:object passed from the front end or client app}STATE_DATA{/hint}' ``` #### Java ```java // Set your X-API-KEY with the API key from the Customer Area.

You will also receive the outcome of the payment asynchronously in a [webhook](/development-resources/webhooks). For card payments, you can receive the following `resultCode` values: | resultCode | Description | Action to take | | -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Authorised** | The payment was successful. | Inform the shopper that the payment has been successful. If you are using [manual capture](/online-payments/capture#manual-capture), you also need to [capture](/online-payments/capture) the payment. | | **Cancelled** | The shopper cancelled the payment. | Ask the shopper if they want to continue with the order, or ask them to select a different payment method. | | **Error** | There was an error when the payment was being processed. For more information, check the [`refusalReason` ](/development-resources/refusal-reasons)field. | Inform the shopper that there was an error processing their payment. | | **Refused** | The payment was refused. For more information, check the [`refusalReason` ](/development-resources/refusal-reasons)field. | Ask the shopper to try the payment again using a different payment method. | ## Test and go live Use our test card numbers to [test how your integration handles different 3D Secure authentication scenarios](/development-resources/testing/3d-secure-2-authentication). When you are ready to [go live](/get-started-with-adyen/#apply-for-your-live-account), follow our [go-live checklist](/online-payments/go-live-checklist/). When using our [live endpoints](/development-resources/live-endpoints/), make sure that all API requests you make for the same payment session use the same live endpoint region. Using different regions for [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) and [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) requests may result in errors when authenticating with 3D Secure. ## See also * [iOS Drop-in integration guide](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in) * [3D Secure 2 API Reference](/online-payments/3d-secure/api-reference) * [3D Secure authentication](/online-payments/3d-secure) * [Webhooks](/development-resources/webhooks)
