How Do I Create a Google Maps API Key for Each Station to Avoid Google’s Daily Load Limits?

Google Maps enforces a daily limit of 25,000 map loads per API key. If you use the same API key for traffic maps across multiple stations, all stations share this limit. Once the limit is reached, your map may display an error, as shown below:

To ensure each station has its own daily limit, you should generate a unique API key for each station. Follow the steps below:

How to Generate a Google Maps API Key for Each Station

1. Log in to your Google account.
2. Visit https://developers.google.com/maps/documentation/javascript/get-api-key.
3. Click the GET A KEY button.
   
4. Enter a project name. We recommend using your station’s name so you can easily track which API key belongs to each station.
   
5. Click Create and Enable API. Your new API key will be generated.
   
6. Copy the API key to your clipboard.

How to Replace the API Key in Your Embedded Google Maps

To update the API key for your existing embedded maps:

1. Go to the Raw HTML widget where the map is embedded.
2. Locate the API key in the map’s embed code.
3. Replace the existing API key with your new one. Insert the new key between key= and the next quotation mark (").

Example:

Repeat this process for each station. By assigning a unique API key to each station, you ensure every station has its own 25,000 daily map load limit, preventing shared overages and maintaining reliable map service for your audience.
