REST Services Examples
Note
Bing Maps Web Control SDK retirement
Bing Maps Web Control SDK is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Web Control SDK until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate from Bing Maps Web Control SDK and Migrate Bing Maps Enterprise applications to Azure Maps with GitHub Copilot.
Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.
The Bing Maps REST services provide a number of APIs which provide several functionalities:
- Geocode Addresses
- Reverse Geocode locations
- Calculate Directions
- Generate static map images
- Get Traffic incident data
- Get elevation data
The Bing Map V8 provides a Search, Direction and Traffic modules which wraps several of the APIs in the Bing Maps REST services. Not all of the APIs are exposed in V8, however even when there is a module, sometimes it is useful to directly access the raw data from the REST services without using the modules.
Accessing the REST services from JavaScript
The Bing Maps REST services can be accessed using GET requests with JSONP. The following examples show how to access the Bing Maps REST Location API to geocode a query and display the matching results in a table using different JavaScript frameworks. All of these examples will look like this in a browser.
Standard JavaScript
REST services can be called using standard JavaScript by simply appending a script tag containing the REST URL to the page.
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
<script type='text/javascript'>
var BingMapsKey = 'Your Bing Maps Key';
function geocode() {
var query = document.getElementById('input').value;
var geocodeRequest = "http://dev.virtualearth.net/REST/v1/Locations?query=" + encodeURIComponent(query) + "&jsonp=GeocodeCallback&key=" + BingMapsKey;
CallRestService(geocodeRequest, GeocodeCallback);
}
function GeocodeCallback(response) {
var output = document.getElementById('output');
if (response &&
response.resourceSets &&
response.resourceSets.length > 0 &&
response.resourceSets[0].resources) {
var results = response.resourceSets[0].resources;
var html = ['<table><tr><td>Name</td><td>Latitude</td><td>Longitude</td></tr>'];
for (var i = 0; i < results.length; i++) {
html.push('<tr><td>', results[i].name, '</td><td>', results[i].point.coordinates[0], '</td><td>', results[i].point.coordinates[1], '</td></tr>');
}
html.push('</table>');
output.innerHTML = html.join('');
} else {
output.innerHTML = "No results found.";
}
}
function CallRestService(request) {
var script = document.createElement("script");
script.setAttribute("type", "text/javascript");
script.setAttribute("src", request);
document.body.appendChild(script);
}
</script>
</head>
<body>
<input type="text" id="input" value="New York" />
<input type="button" onClick="geocode()" value="Search" /><br />
<div id="output"></div>
</body>
</html>
jQuery
JQuery is a very popular JavaScript framework that makes it easier to developer JavaScript that works across different browsers. jQuery provides three of different functions to make HTTP GET requests to services; jQuery.ajax ($.ajax), jQuery.get ($.get) and jQuery.getJSON ($.getJSON). The jQuery.get and jQuery.getJSON function is meant to be a simplified version of the jQuery.ajax function but have less functionality. The jQuery.get and jQuery.getJSON functions do not support cross-domain requests or JSONP whereas the jQuery.ajax function does. In order to make a cross-domain request using the jQuery.ajax function you have to specify that it uses JSONP and set the dataType property to JSONP.

Angular 1.0
AngularJS is an open source JavaScript framework that lets you build well structured, easily testable and maintainable front-end applications by using the Model-View-Controller (MVC) pattern. AngularJS has a function $http.jsonp which allows you to easily make JSONP requests. Angular requires that JSONP parameter of the REST request URL point to JSON_CALLBACK.

Angular 1.6
Angular 1.6 has changed how it handles JSONP. First off you need to allowlist the Bing Maps REST Services in your app config. Additionally, instead of using success and error functions, Angular 1.6 now uses a then function. Finally, the hardcoded &jsonp=JSON_CALLBACK value is no longer supported, and instead the jsonpCallbackParam option needs to be used in the request.
