    These kinds of free websites all carry this risk. If users need automatic currency adjustment, I generally recommend using a bank's paid service.

    Hi,
     
    You need to provide service URL in the Exchange rate service screen.
     
     
    1- In Business Central Open Exchange Rate Services
    3 - Toogle enable
    4 - You can also check preview.

    Hello,
     
    This error with the XE Currency Data plugin (“The Service URL field must not be blank”) typically occurs because the Service URL value doesn’t properly persist in the database, leaving it effectively empty; the quick fix is to temporarily replace the Service URL with http://www.floatrates.com/daily/usd.xml and save to force validation and write the value, then change it back to https://xecdapi.xe.com/v1 and save again, which correctly reinitializes and stores the field so the XE API works normally.

    The XE.com currency exchange API is producing a significant number of errors. It may be better to switch to a more reliable exchange rate API, such as Fixer.io or AllRatesToday.
