Swish for API only

Add Swish to an existing API-only integration.

Accept Swish payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.

Before you begin

These instructions explain how to add Swish to your existing API-only integration. The API-only integration works the same way for all payment methods. If you haven't yet done this integration, refer to our API-only integration guide.

Before starting your Swish integration:

  1. Make sure that you have set up your back end implementation.
  2. Add Swish in your test Customer Area.

Build your payment form for Swish

Show Swish as an available payment method in your payment form. You don't need to collect any information from the shopper in your payment form.

We provide a Swish logo which you can use on your payment form. For more information, refer to Downloading logos.

You can also submit a /paymentMethods request specifying:

  • countryCode: SE
  • amount.currency: SEK.

In the response, you receive paymentMethod.type: swish.

Make a payment

When a shopper chooses to pay with Swish, you need to redirect them to the Swish app, depending on how they are accessing your site:

  • For shoppers on mobile, redirect to the Swish app. If this fails, present a QR code as a fallback.
  • For shoppers on desktop or laptop, present a QR code.
  1. From your server, make a /payments request, providing:

    • paymentMethod.type: swish
    • returnUrl: Make sure that the returnUrl is an HTTPS url.

    The following code sample is a /payments request for a Swish payment.

    curl https://checkout-test.adyen.com/v52/payments \
    -H "x-API-key: YOUR_X-API-KEY" \
    -H "content-type: application/json" \

    The /payments response contains:

    • action: Object containing information that you will need to generate the QR code or redirect to the Swish app.
    {
        "resultCode": "Pending",
        "action": {
            "qrCodeData": "D4XJQf4wJSQWYGBUue55Wy8TiV7t_r5vC",
            "paymentMethodType": "swish",
            "type": "qrCode",
            "paymentData": "Ab02b4c0!...==",
            "url": "swish://paymentrequest?..."
        }
    }

Present QR code

  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'll send a notification webhook informing you of the payment result.
  3. Once the shopper finalises the payment, redirect them to your website, and present the payment result.

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

You will also receive the outcome of the payment asynchronously in a notification webhook.

The resultCode values you can receive for Swish are:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment was successful.
Cancelled The shopper cancelled the payment. Ask the shopper whether 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 field. Inform the shopper that there was an error processing their payment.
Pending
Received
The payment order was successfully received. Inform the shopper that you've received their order, and are waiting for the payment to clear.
You will receive the final result of the payment in an AUTHORISATION notification.
Refused The payment was refused. For more information, check the refusalReason field. Ask the shopper to try the payment again using a different payment method.

Test and go live

You need to contact Swish to set up a test account. Check the status of Swish test payments in your Customer Area > Transactions > Payments.

Before you can accept live Swish payments, you need to submit a request for Swish in your live Customer Area.
