We need to update the currency rates everyday with live values. Do you know if there is something we can use from the api for this? Or do we have to do some custom development?
The conversion rates are saved in the database, so it is quite easy to update them using the data integration module.
There is no webservice or similar, but the api for the is available in the Dynamicweb.ecommerce.international.Currency, where you can set the rates in code, if needed.
