As of April 2023, we claimed our own Swish certificate and have officially become a so-called Technical Supplier which will help us onboarding new customers.
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.
Make sure the customer chose 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.
Set the Client certificate thumbprint value on the Mobile Invoice Setup page as DF3BBAD114D6F0A754E5316FE2A86A614BD8A339 and provide the client’s Merchant ID
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: New certificate also supports working with existing customers, hence their configurations can be changed at any time if desired.
