Most integrations have a misc setting section also which looks like this:
Currency - This option allows you to select the currency you want this channel to be in
Language - You can set the language that channel will be in.
Calculate Shipping Tax - If enabled we will calculate shipping tax based on the shipping paid and the shipping tax value set against the shipping method that was applied.
Default Pricing Profile - This option is not applicable to all users, but for customers using pricing profiles this allows you to set a pricing profile that will get applied to all listings for that channel by default
Channel Percentage Fees - This field is linked to pricing profiles and can be used as part of your pricing profile setup.
