Get started

Follow these steps to get set up with the Advanced Markers Preview.

Get an API key and enable the Maps JavaScript API

Before using the Advanced Markers preview, you need a Cloud project with a billing account, and the Maps JavaScript API enabled. To learn more, see Set up your Google Cloud project.

Get an API key

Create a map ID

To create a new map ID, follow the steps in Cloud customization. Set the Map type to JavaScript, and select either the Vector or Raster option.

Update your map initialization code

This requires the map ID you just created. It can be found on your Maps Management page.

1. Use v=beta and libraries=marker in your API script tag. For example:

   <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&v=beta&libraries=marker&callback=initMap"></script>

2. Provide a map ID when you instantiate the map using the mapId property. This can be a map ID that you provide, or DEMO_MAP_ID.

   const map = new
   google.maps.Map(document.getElementById('map'), {
     center: {lat: -34.397, lng: 150.644},
     zoom: 8,
     mapId: 'YOUR_MAP_ID'
   });

Check map capabilities (optional)

Advanced Markers requires a map ID. If the map ID is missing, or an invalid map ID is passed, Advanced Markers cannot load. As a troubleshooting step, you can add a mapcapabilities_changed listener to subscribe to map capability changes. This will indicate whether the following conditions have been met:

• A valid map ID is in use.
• The map ID is associated with a vector map, if features requiring a vector map are in use.

Using Map Capabilities is optional, and recommended only for testing and troubleshooting purposes, or for runtime fallback purposes.

// Optional: subscribe to map capability changes.
map.addListener('mapcapabilities_changed', () => {
  const mapCapabilities = map.getMapCapabilities();

  if (!mapCapabilities.isAdvancedMarkersAvailable) {
    // Advanced markers are *not* available, add a fallback.
  }
});
