Use different Fortnox articles for the shipping fee depending on the shipping method the customer chose.
Each row connects:
a shipping method from your webshop, and
a Fortnox article number.
Good to know
Shipping methods that are not mapped, or don't match, use Default Article number used for Shipping Fee.
This is shown when Shipping fee as an Order Line is turned on.
Type each value exactly as your webshop sends it – same spelling and same upper/lower case. A value that doesn't match is skipped without an error, and the default is used instead.
