In such case, you should enable multi-currency handling and create API calls that pass the transaction currency to Partnero. *** ### How it works When multi-currency handling is **enabled** for your program, Partnero API will check for *amount\_units* information with every transaction API call. * If the *amount\_units* does not match the default program currency, we will use a trusted 3rd-party service to convert the transaction value to the default program currency at the time of purchase. * If the *amount\_units* is not provided, the default program currency will be used. * If the multi-currency handling **is not enabled**, *amount\_units* will be ignored. Please see our [API Documentation](https://developers.partnero.com/reference/transactions.html) for detailed instructions. #### To enable multi-currency handling: 1. In your affiliate program, go to **Settings** under **Program**. 2. Scroll down to **Commission** and toggle to Enable the multi-currency conversion for the program: 3. Click **Update**. *** ### Conversion rates We use a trusted 3rd-party service to pull conversion rates at the time of the transaction. The service provides real-time exchange rate data for 170 world currencies, updated every 60 seconds. Currency data is sourced from financial data providers and banks, including the European Central Bank.
