As of April 2023, we claimed our own Swish certificate and have officially become a so-called Technical Supplierwhich will help us onboarding new customers. It will be valid until Tuesday, April 18, 2028 1:50:22 PM
The main advantage and purpose of using our own certificate is to get rid of the hassle while creating new certificates per customer as shown here Swish
Our partner certificate is re-usable for more than 1 customer. We just need to set 2 things as described below and our new customer will be ready to use Swish payments.
Ensure the customer chooses LINK Mobility AB as their technical supplier on bank account settings. Currently, Swedbank, Handelsbanken, Nordea, Danske Bank, Länsförsäkringar Bank, and SEB offer the technical supplier solution.
Provide the client’st Merchant ID and turn on the Use technical supplier certificate toggle. Keep in mind that the Client certificate thumbprint value is no longer necessary and will be removed in the upcoming releases.
From this point on, you will be able to create transactions with our client certificate on behalf of the merchant that is provided on the setup page.
PS: The new certificate also supports working with existing customers, hence their configurations can be changed at any time if desired.
