how to get the service url while configuring currency exchange rate service and how to edit or change the URL once saved.
Hi, perhaps these links will be of some help:

https://support.opendoorerp.com/support/solutions/articles/17000066690-setup-free-currency-exchange-rate-service-feed-for-nav (this is for NAV but should give you a good idea of how to setup the Data Exchange Definition).
