This section provides information on the minimum setup required to quickly begin using the . For more detailed information on HERE account setup, app registration, and authentication, see the Identity & Access Management Developer Guide.
Get a HERE Account
If your organization has signed up for HERE Workspace or HERE Marketplace, contact your organization admin who can invite you to join the HERE platform organization established for your company. You can also request a free trial of the HERE platform if your company does not have an organization established for it. For more information, see the HERE platform pricing.
Register your App
To register your app, follow these steps:
Sign in to the HERE platform using your HERE account.
Open the Access Manager from the Launcher.
On the Apps tab, click Register new app and provide the requested information.
Click Register. The platform creates a new app with a unique app ID.
Get an API Key
To get an API key, follow these steps:
Sign in to the HERE platform using your HERE account.
Open the Access Manager from the Launcher.
On the Apps tab, click the app you created in the previous section, Register your App, or an existing group app for which you want to generate an API key.
On the Credentials tab, select API Keys then click Create API key to generate a maximum of two API Keys for your application authentication credentials. The API key is created and displayed.
Creating a Sample Application
The use case is to create an application that displays a default map, which is non-interactive.
Its implementation uses JavaScript code to display the map in an HTML page and consists of the following steps:
The first step for any application based on the HERE Maps API for JavaScript is to load the necessary code libraries or modules. The implementation of our basic use case requires two modules: core and service (see also HERE Maps API for JavaScript Modules).
To load the modules, add the following <script> elements to the <head> of the HTML document:
The URL in the "src" attribute contains a version number that reflects the latest major release of the API. Note that this version number changes with each new release, which may break backwards-compatibility – for more information, see API versions.
Alternatively the API can be loaded as an EcmaScript 6 module:
An essential part of creating a working application with the HERE Maps API for JavaScript is to establish communication with the back-end services provided by HERE REST APIs. In our scenario, the back-end services process requests for the map data and delivers it to the application for display.
For this purpose, initialize a Platform object with the apikey you received on registration:
var platform =newH.service.Platform({'apikey':'{YOUR_API_KEY}'});
Furthermore, the object provides methods that allow for easy creation of fully working service stubs, such as map tile service stubs, routing service stubs, and so on.
Continuing with this scenario, the application will display a non-interactive map centered on a predefined location at a fixed zoom level. To implement this effect:
Create an HTML container element in which the map can be rendered (for example, a div).
Instantiate an H.Map object, specifying:
the map container element
the map type to use
the zoom level at which to display the map
the geographic coordinates of the point on which to center the map
The implemenation JavaScript code shown below sets up a Map object, specifying the normal map type, zoom level 10, and the map center as a location near Berlin, Germany, given by latitude 52.5 and longitude 13.4:
// Obtain the default map types from the platform object:var defaultLayers = platform.createDefaultLayers();// Instantiate (and display) a map object:var map =newH.Map(
document.getElementById('mapContainer'),
defaultLayers.vector.normal.map,{
zoom:10,
center:{ lat:52.5, lng:13.4}});
The implementation displays the following map image:

Below, you can find the complete source code that implements the basic scenario:

// Initialize the platform object:
var platform = new H.service.Platform({
'apikey': '{YOUR_API_KEY}'
});
// Obtain the default map types from the platform object
var maptypes = platform.createDefaultLayers();
// Instantiate (and display) a map object:
var map = new H.Map(
document.getElementById('mapContainer'),
maptypes.vector.normal.map,
{
zoom: 10,
center: { lng: 13.4, lat: 52.51 }
});
</script></body></html>
