The following method calls the Google Maps Distant Matrix API to calculate the distance between the Dam in Amsterdam and the Coolsingel in Rotterdam:

    {"Content-Type": "application/json"}

The result is a JSON object with the answer of the REST-service. The above mentioned request returned:

{  "destination_addresses" : [ "Coolsingel, Rotterdam, Netherlands" ],
   "origin_addresses" : [ "Dam, Amsterdam, Netherlands" ],
   "rows" : [
         "elements" : [
               "distance" : {
                  "text" : "76.1 km",
                  "value" : 76140
               "duration" : {
                  "text" : "1 hour 3 mins",
                  "value" : 3809
               "status" : "OK"
   "status" : "OK"

You can use the result as a variable in the rest of the script, for instance:

response = JSON.parse(response);
console.log("The distance is " + response.rows[0].elements[0].distance.text);
