# IRIS for API only

Add IRIS to your API-only integration.

[View source](/payment-methods/iris/api-only.md)

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

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).                                                                                                                                                                                                  |   |
| **Action handling**  | Make sure that your existing integration is set up to [handle the additional action](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#additional-action). `action.type`: **redirect** and **qrCode**.                                                                                                          |   |
| **Setup steps**      | - Before you begin, [add IRIS in your Customer Area](/payment-methods/add-payment-methods). - Before you can go live, [request the IRIS payment method](/payment-methods/iris#onboarding) from your Greek bank, and from Adyen, by submitting your DIAS code, as well as the merchant account and the associated stores you want to have it activated on. |   |

## How it works

1. The shopper selects IRIS as the payment method.

2. Then, there are two flows possible:

   * Issuer-redirect: A list of issuers is shown, and the shopper selects their issuing bank. The shopper is then redirected to the issuing bank and completes the payment. The shopper is then redirected back to your page.
     * Issuer-redirect flow is applicable to Mobile and Desktop checkout scenarios
   * QR-code: a QR code is shown, which the shopper scans with the issuer app. The shopper completes the payment in the app on their device. You will be notified of the payment result.
     * QR code flow is intended for Desktop only; on mobile this flow is not recommended, because often the app used for scanning the QR code resides on the same device.

3. You complete the order.

## Build your payment form

Include fields to collect important information from your shopper in the payment form.

For the Issuer-redirect flow you need to show a list of issuing banks. The list of issuing banks is included in the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) response. The list may include the following banks:

| Bank name               | Issuer ID |
| ----------------------- | --------- |
| Piraeus Bank            | PIRBGRAA  |
| Eurobank                | ERBKGRAA  |
| National Bank of Greece | ETHNGRAA  |
| Alpha Bank              | CRBAGRAA  |
| Viva                    | PRXBGRAA  |
| CrediaBank              | ATTIGRAA  |

You can [download the logo for IRIS](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%2Bonly\&version=71#downloading-logos) to use in your form.

We also provide logos for the issuing banks, which you can use on your payment form. For more information, refer to [downloading logos](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%2Bonly\&version=71#downloading-logos).

## Get IRIS 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 IRIS is included in the response.

| Parameter                                                                                                          | Values  |
| ------------------------------------------------------------------------------------------------------------------ | ------- |
| [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-countryCode)         | **GR**  |
| [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount-currency) | **EUR** |

In the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response, note the `action` object. This contains the information needed to redirect the shopper.

**Example response**

```json
{
    "resultCode":"RedirectShopper",
    "action":{
        "paymentMethodType":"iris",
        "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 the following recommendations into consideration:

   * 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.

**Example /payments/details**

#### curl

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

```

In the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response, note the `action` object. This contains the information needed to generate the QR code.

**Example response**

```json
{
    "pspReference": "BCMSN9N347C68775",
    "resultCode":"Pending",
    "action":{
        "paymentData": "Ab02b4c0!BQABAgCpM2q6...==",
        "paymentMethodType":"iris",
        "method":"GET",
        "qrCodeData":"IRISCOMf1443214-1cec-4ffa-8378-5a1d6a60cfef",
        "type":"qrCode"
    }
}
```

After initiating the payment, the shopper has 10 minutes to complete the transaction. We recommend that you show this timer to the shopper.

#### Present the QR code

Follow these steps to render the QR code on your checkout page:

1. Use the `qrCodeData` from the `action` object to render the QR code on your checkout page.
2. After the shopper scans the QR code and completes the payment, we send a webhook informing you of the payment result.
3. Present the payment result to your shopper.

## Present the payment result

Use the `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, or wait for a webhook to know the outcome of the payment.

The `resultCode` values you can receive for IRIS payments are:

| resultCode          | Description                                                                                                                                      | Action to take                                                                                                                                                                                                                                               |

The [webhooks](https://docs.adyen.com/development-resources/webhooks/webhook-types) you can receive for IRIS are:

| eventCode     | success field | Description                                     | Action to take                                                                      |
| ------------- | ------------- | ----------------------------------------------- | ----------------------------------------------------------------------------------- |
| AUTHORISATION | false         | The transaction failed.                         | Cancel the order and inform the shopper that the payment failed.                    |
| AUTHORISATION | true          | The shopper successfully completed the payment. | Inform the shopper that the payment has been successful and proceed with the order. |

In the QR code flow, you have to wait for [webhooks](https://docs.adyen.com/development-resources/webhooks/webhook-types) to know the outcome of the payment. This also applies to the Issuer redirect flow, if the shopper failed to return to your website or app.

## Test and go live

Before you accept live payments, test your integration using Adyen’s IRIS simulator. In this simulator, the payment outcome (**Successful**, **Refused**, or **Cancelled**) can be selected on an Adyen-hosted page. This page will load depending on the IRIS flow:

* Issuer redirect flow: the page URL is in the redirect link in Adyen’s /payments response.
* QR code (Ecommerce and In-person Payments): the page URL is encoded in the QR code, which can be opened with any smartphone camera.

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

Before you go live, go through the onboarding steps with your Greek bank, and enable IRIS payment method for your live merchant account on [Customer Area](https://ca-live.adyen.com/).
