# Online banking Czech Republic for API only

Add Online banking Czech Republic to your API-only integration.

[View source](/payment-methods/online-banking-czech-republic/api-only.md)

You can add Online banking Czech Republic to your existing integration. The following instructions show only what you must add to your integration specifically for Online banking Czech Republic.

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.

## Requirements

| Requirement           | Description                                                                                                                                                                                                                |   |
| --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type**  | Make sure that you have an existing [API-only integration](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only).                                                                   |   |
| **Redirect handling** | Make sure that your existing integration is set up to [handle the redirect](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#handle-the-redirect). `action.type`: **redirect**. |   |
| **Setup steps**       | Before you begin, [add Online banking Czech Republic in your Customer Area](/payment-methods/add-payment-methods).                                                                                                         |   |

## How it works

1. The shopper selects Online banking Czech Republic as the payment method.
2. The shopper enters their details in the [payment form that you build](#build-your-payment-form).
3. When you make the payment request, you [include additional information about the items that the shopper intends to purchase](#additional-parameters-payments).

## Build your payment form

To show Online banking Czech Republic in your payment form, you need to:

1. Show a list of available banks to your shopper.
2. After the shopper selects a bank, pass the corresponding **Issuer** value to your server. You will need this to make a payment.

| Bank name              | Issuer ID |
| ---------------------- | --------- |
| Česká spořitelna       | cs        |
| Komercní banka         | kb        |
| mTransfer              | mp        |
| Fio banka              | pf        |
| Moneta Money Bank      | pg        |
| Raiffeisenbank ePlatby | rf        |

You can also get the issuer list from the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) response, as explained in the [API-only integration guide](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only\&version=71#get-available-payment-methods).

## Get Online banking Czech Republic as an available payment method

When you make the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) to [get available payment methods](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#get-available-payment-methods), specify the following so that Online banking Czech Republic is included in the response.

| Parameter                                                                                                          | Values                    |
| ------------------------------------------------------------------------------------------------------------------ | ------------------------- |
| [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-countryCode)         | **CZ**                    |
| [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount-currency) | **CZK**                   |
| [amount](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount)                   | The value of the payment. |

// Send the request
const checkoutAPI = new CheckoutAPI(client);
const response = checkoutAPI.PaymentsApi.payments(paymentRequest, { idempotencyKey: "UUID" });
```

The response includes `action.type`: **redirect**.

**Example response with a redirect action**

```json
{
    "resultCode":"RedirectShopper",
    "action":{
        "paymentMethodType":"onlineBanking_CZ",
        "method":"GET",
        "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
        "type":"redirect"
    }
}
```

## Handle the redirect

1. To complete the payment, redirect the shopper to the `action.url` returned in the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response, taking into account the following recommendations:

   * **When using the HTTP GET method:**\
     For security reasons, when showing the redirect in the app, we recommend that you use [SFSafariViewController](https://developer.apple.com/documentation/safariservices/sfsafariviewcontroller) for iOS or [Chrome Custom Tabs](https://developer.chrome.com/multidevice/android/customtabs) for Android, instead of WebView objects. Also refer to the [security best practices](https://developer.android.com/topic/security/best-practices#webview) for WebView.

   * **Redirection for mobile integrations:**\
     For mobile integrations, we strongly recommended that you redirect the shopper to the default browser of their device. Redirecting to the default browser ensures the best compatibility, handling of multi-factor authentication, app-to-app redirection, and error handling.

2. After the shopper is redirected back to your website, check the payment result by making a POST [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request, specifying:

   * `details`: object that contains the URL-decoded `redirectResult` returned when the shopper was redirected back to your site.

   **/payments/details request**

   ```bash
   curl https://checkout-test.adyen.com/v72/payments/details \
   -H 'x-api-key: ADYEN_API_KEY' \
   -H 'content-type: application/json' \
   -d '{
      "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
      }
   }'
   ```

3. In the response note the following:

   * `resultCode`: use this to present the result to your shopper.
   * `pspReference`: our unique identifier for the transaction.

   **/payments/details response**

   ```json
   {
      "resultCode": "Authorised",
      "pspReference": "V4HZ4RBFJGXXGN82"
   }
   ```

## Present the payment result

Use the  [resultCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details#responses-200-resultCode) that you received in the [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) response to present the payment result to your shopper.
