Using the POI API

Query the POI REST API. When you click on the map, this example will search and display markers for any nearby POIs. To set up places on your map that can be searched, use the Places Designer with your API key.

This is an optional component with a few dependencies. To use it, you will have to include poi_api.js as shown in the code sample below.
