Pay with Swish

Important

Introduced in Android version 2.5.0 and iOS version 3.3.0.

In order to make a payment using Swish, a URL to launch the application needs to be obtained by calling the getSwishUrl function using a payment token provided by your server.

After obtaining this URL, the app should use it to create an intent and launch the Swish App.
The URLs are constructed in a way so that you should not need to process it before launching Swish from your app.

Once the Swish intent is handled, the app should call getPaymentResponse in order to obtain the payment status. Swish Flow

Please note

Even though we have chosen to name both iOS and Android functions getSwishUrl, the Android SDK returns an URI object for easier usage.

Get Swish URL

Parameter	Description
paymentToken	A valid payment token from your backend.
callbackUrl	A valid URL for returning to the application.
receiveOn	The dispatch queue used when invoking the result callback handler. Defaults to main.
onResult	Result callback handler.

SveaAppWallet.shared.getSwishUrl(paymentToken: paymentToken, callbackUrl: URL) { [weak self] result in
    switch result {
    case .success(let swishUrl):
        // Using swish url open Swish if installed.
        UIApplication.shared.open(swishUrl. options: [:], completionHandler: nil])
    case .failure(let error):
        print("Could not get swish url, got error: \(error)")
    }
}

`onSuccess`

Returned when a URL to used to launch swish is successfully generated

`onFailure`

Returned when an error occurs.

Possible errors

case noPaymentTokenProvided     // No payment token was found
case failedToGetSwishUrl        // The request could not be completed.

Get payment response

Returns the status of a Swish payment

Parameter	Description
receiveOn	The dispatch queue used when invoking the result callback handler. Defaults to main.
onResult	Result callback handler.

Please note

SveaWalletClient is deprecated in version 3.1.0. Use new class SveaAppWallet instead.

Test Swish payments

We provide several options to test Swish payments in the stage environment. Unless otherwise specified, Swish mock will be used for new projects.

Swish mock

Swish mock is a web app that that simulates the Swish client. When configured for Swish mock, the example code above will open Swish mock in the default browser, and you will get options to test different scenarios.

Complete payment

To complete a payment in Swish mock, press Pay, Decline or Error. This will result in the payment being completed with a corresponding status.

Note that the browser tab will stay open until you close it.

Test with callbackUrl

If you entered a callbackUrl to your application you will get the option to use it when completing the payment.

Note that some browsers will not work properly with this option

Test with callback delay

You can simulate delayed callbacks from either the Swish server or the Swish Client. This can be useful if you want to test your implementation for race conditions.

To use the client callback delay you must also use the callbackUrl. A server callback delay does not require the callbackUrl, but you can use it for more precise timing.

Fail to create a payment

By entering amount 5.01 the payment will fail straight away, simulating an error from the Swish server.

Merchant Swish Simulator

The official Merchant Swish Simulator can be used for testing without a Swish client.

Swish Sandbox

The official Swish Sandbox can be used for a more realistic test. Follow the link for instructions on how to set it up.
