What is a merchant ID?

A merchant ID (MID) is a unique merchant identification code assigned to every merchant using Klarna. MID consists of a letter followed by numbers (e.g., P963369).

Not sure what your MID is? Go to Settings in the Merchant portal, and you’ll find your MID on your Store information page.
