Page Summary
-
This tool uses the Google Maps Places API to locate a place based on its address.
-
It then places a marker on the map at the located place's coordinates.
-
An info window is displayed, containing the place's ID, name, and formatted address.
-
Sample code is provided in both JavaScript and TypeScript, demonstrating the functionality.
The Place ID Findersample allows a user to find a place based on its address, then it adds a marker for the place to the map, and displays the place's place ID in an info window.
