How to Convert USD to EUR in JavaScript

If you have a large international customer base, integrating exchange rate and conversion tools into your applications is a great way to improve your online commerce experience. Utilizing the following API in JavaScript will allow you to automatically convert any source currency into any available destination currency with constantly updated exchange rate data.

We will begin by installing the jQuery library:

bower install jquery

Once the installation is complete, we can call our API function:

var settings = {
     "url": "https://api.cloudmersive.com/currency/exchange-rates/convert/<string>/to/<string>",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "Content-Type": "application/json",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "data": JSON.stringify("<double>"),
};
$.ajax(settings).done(function (response) {
     console.log(response);
});

The only inputs needed for the above operation are the source and destination currency ISO codes, the price to convert, and your API key.
