When EffectConnect imports an order from a marketplace, it will be imported with the currency that applies in that specific country. In some situations, EffectConnect will convert the currency to Euro, in other situations the currency remains the same. When you open the order in EffectConnect, you will always be able to see the original currency the order has.
If you're using a pre-built connection that uses an installation from an app store or plugin (like for example Lightspeed, CCV shop. OpenCart) EffectConnect will convert the currency to Euro.
If you're using a custom API connection, for example, a connection you wrote yourself onto our custom API, you'll import the orders yourself and then will receive the order amount in the currency of the marketplace, EffectConnect will then do no conversion of the currency.
Please keep in mind that EffectConnect imports all the currencies every 24 hours.
