## What you get

- **Card payments**: Visa, Mastercard, American Express and the other card brands enabled on your Adyen account.
- **3D Secure 2**: bank verification opens inside the checkout, and shoppers can cancel it. For banks that use a redirect, shoppers continue to their bank's page and come back to the checkout's payment step.
- **Authorize, then capture**: cards are authorized when the shopper pays and captured when the order is placed. The amount authorized is always the cart total, calculated by the app on the server.
- **Refunds**: full and partial refunds from the Swell dashboard go through Adyen.
- **Subscriptions**: the card is saved with Adyen at checkout, and subscription renewals charge it automatically.
- **Test and live**: switch between Adyen's test and live environments in the app settings.
- **Signed webhooks**: Adyen notifications are verified with your HMAC key before they're processed.

:::warning
**Selling subscriptions?** Ask Adyen support to enable **merchant-initiated (recurring) card payments** on your account before your first renewal. Without it, Adyen declines every renewal with `14_029` "Required field 'cvc' is not provided". [Here's what to ask](/before-you-start#ask-adyen-to-enable-recurring-card-payments).

## Setup at a glance

Setup takes about 15 minutes. You'll move between two places: your **Swell dashboard** and the **Adyen Customer Area**.

1. **Check your Adyen account**

    Manual capture, plus the recurring options if you sell subscriptions. See [Before you start](/before-you-start).

2. **Copy your Adyen keys**

    API key, client key and merchant account. See [Connect your Adyen account](/setup/connect-adyen).

3. **Allow the payment form's origin**

    So Adyen accepts the card form on your checkout. See [Allowed origins](/setup/allowed-origins).

4. **Set up the webhook**

    So Adyen can report failed captures and refunds. See [Webhook](/setup/webhook).

5. **Enable Adyen and place a test order**

    See [Test your setup](/setup/test-order).

**[Before you start](/before-you-start)**

Adyen account requirements.

**[Going live](/going-live)**

Switch from test to live payments.
