Fetch exchange rate using API request from the response object

The following code will teach you to call and request information from the endpoint

This is another way of getting a value from API request.

 let headersRequest = {
                        'Content-Type': 'application/json'
                    }
                    let apiUrl = "https://api.freecurrencyapi.com/v1/latest?apikey=fca_live_9YbQtanAqpYwy8475QRWA7fJotFsvOF8Mqo6KccW&currencies="+transactionCurrency+"&base_currency=INR"
                     let response = https.request({
                        method:https.Method.GET,
                        url: apiUrl,
                        body:transactionCurrency,
                        headers: headersRequest
                    });
                    if(response.code == 200){
                    let exchangerateResponse = JSON.parse(response.body);
                    let exchangeRate = exchangerateResponse.data[transactionCurrency];
                    let calAmount = feeAmount * exchangeRate;

if the output like this

 {
"data":
       {
"USD":0.0119264751
       }
}
