Dear creator's community

I need help with this api request, I checked on the support online and on the form but it’s very confusing for me because there are different type of supports between the old version and the new version,

I would like to get the api for the distance matrix between two area.

 I've tryed to create this code but of course doesn't work

MapResponse = getUrl((("https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=" + input.Origin) + "&destinations=" + input.Destination) + "&key=A*****************************M");

Tot_KM = MapResponse.executeXPath("/distance/value()");

My goal is to get the distance between two area that my user insert, I would like that the result will be in a “Tot km” field.

I used a debug on user input.

I will attached here the json answer:
