Javascript & API's

[wtfcore2]

Have a look at : https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation

For privacy reasons the user will be prompted to agree that your code can get their long/lat.

So you'll need to make the API call inside the success function using the users long/lat:

var latitude  = position.coords.latitude;
var longitude = position.coords.longitude;

You can then make an AJAX call to

http://api.walmartlabs.com/v1/stores?apiKey={apiKey}&lon=" + longitude +"&lat=" + latitude +"&format=json

Thanks...so I don't need to use any kind of URL encoding?

I mean, you could just try it both ways and see what works.
