Starter – Instrument Mode

Instrument Mode

This feature is only available for merchants who have a specific agreement with Swedbank Pay.

With “Instrument Mode”, the Payment Menu will display only one specific payment instrument instead of all those configured on your merchant account. The PaymentOrder resource works just like it otherwise would, allowing you to remain largely indifferent to the payment instrument in use. To use the feature you need to add the instrument field in the request as shown in the example below.

It is important to only create one paymentOrder for each purchase, even if the payer changes their mind and wants to use another payment instrument. This is because we don’t allow creating multiple paymentOrders with the same payeeReference. If this happens, you should use the PATCH request below to reflect what the payer has chosen instead of creating a new paymentOrder. This way, you can still use the same payeeReference.

If you don’t want to use Swedbank Pay’s Payment Menu (e.g. building your own payment menu), or have multiple payment providers on your site, we strongly recommend that you implement this functionality. In this case you should use the instrument field to enforce which payment instrument to show. If you have an agreement with Swedbank Pay for both Card and Swish/Vipps processing, and the payer chooses either of these instruments, you should add the instrument parameter with the specific payment instrument.

Eligibility Check

If you want to build your own menu and display at least one wallet like Apple Pay, Click to Pay or Google Pay™, you need to do an eligibility check. This is to ensure that the wallet is supported on the payer’s device or browser.

Swedbank Pay provides a script to do this check, with the URL ecom.<environment>.payex.com/checkout/core/integration. Environments available for you are externalintegration and production, and you can switch integration between checkout and paymentmenu. Follow these links for test environment and production environment Checkout scripts.

Add the script tag to your website and do an await payex.getAcceptedWallets(). We will return a string array with the wallets eligible for that purchase. The format will e.g. be ["applepay"].

If you are not building your own menu or don’t offer these wallets, there is no need to run the script to do the check.

Instrument Mode Request

An example with invoice as the instrument of choice.

PATCH Instrument Selection

Note the rel named set-instrument, which appears among the available operations in the paymentOrder response when instrument mode is applied.

To switch instrument after the paymentOrder has been created, you can use the following PATCH request, here with Swish as an example.
