# Swish Flutter Component

Add Swish to your Components integration.

[View source](/payment-methods/swish/flutter-component.md)

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

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

What you must add to your integration depends on the [server-side flow](/online-payments/build-your-integration) that your integration uses:

## Sessions flow Component

## Requirements

| Requirement          | Description                                                                                                                                                                      |   |
| -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type** | Make sure that you have an existing Sessions flow [Flutter Components integration](/online-payments/build-your-integration/advanced-flow?platform=Flutter\&integration=Drop-in). |   |
| **Checkout API**     | Make sure that you use Checkout API v68 or later.                                                                                                                                |   |
| **Setup steps**      | Before you begin, [add Swish in your Customer Area](/payment-methods/add-payment-methods).                                                                                       |   |

### Additional Parameters Sessions Request

## Add additional parameters to your /sessions request

You do not need to add any parameters when you [create a payment session](/online-payments/build-your-integration/sessions-flow?platform=Flutter\&integration=Components#create-a-payment-session).

### Additional Configuration

## Add additional configuration for Swish

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

## Test and go live

When you make a Swish payment in the test environment, the payment is authorised within 15 seconds. You can simulate different refusal scenarios, as outlined in the [Merchant Swish Simulator](https://developer.swish.nu/api/mss/v1), by adding the error code to the `shopperStatement` property. For example, `"shopperStatement": "FF08"`.

Check the status of Swish test payments in your **Customer Area** > **Transactions** > **Payments**.

To accept live Swish payments, you must [submit a request for Swish](/payment-methods/add-payment-methods) in your [live Customer Area](https://ca-live.adyen.com/).
