You're all set!

To start developing, please head over to our developer documentation.

Activate the Google Maps JavaScript API

To get you started we'll guide you through the Google Developers Console to do a few things first:

  1. Create or choose a project
  2. Activate the Google Maps JavaScript API and related services
  3. Create appropriate keys

Custom Marker Symbols

Read the documentation or view this example fullscreen.

// This example uses SVG path notation to add a vector-based symbol
// as the icon for a marker. The resulting icon is a star-shaped symbol
// with a pale yellow fill and a thick yellow border.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: -25.363882, lng: 131.044922}
  });

  var goldStar = {
    path: 'M 125,5 155,90 245,90 175,145 200,230 125,180 50,230 75,145 5,90 95,90 z',
    fillColor: 'yellow',
    fillOpacity: 0.8,
    scale: 1,
    strokeColor: 'gold',
    strokeWeight: 14
  };

  var marker = new google.maps.Marker({
    position: map.getCenter(),
    icon: goldStar,
    map: map
  });
}
<div id="map"></div>
/* Always set the map height explicitly to define the size of the div
 * element that contains the map. */
#map {
  height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}
<!-- Replace the value of the key parameter with your own API key. -->
