The Reach /localize GET API call is used to retrieve locale data from the Reach system. When you have to get FX rates for a particular currency, calling the /localize api call with the right parameters gives the converted response you need.

🚧

Using POST instead of GET

While the /localize api endpoint works on both GET and POST, we highly recommend a POST call if you have a large product base and would need to do a large batch call.
