What is a merchant ID?
Merchant ID (MID) is the unique merchant identification code assigned to each business using Klarna.
The MID starts with an alphabetical character, followed by a series of unique numbers in the format PKXXXX.
Not sure what your MID is?
Go to Settings in the Merchant Portal, and you’ll find your MID on your Store information page.
