The Java Client, Python Client, Go Client and Node.js Client for Google Maps Services are community supported client libraries, open sourced under the Apache 2.0 License. They are available for download and contributions on GitHub, where you will also find installation instructions and sample code:

- Node.js Client for Google Maps Services
Why use the client libraries?
The Java Client, Python Client, Go Client and Node.js Client for Google Maps Services enable you to work with Google Maps web services on your server. They wrap the functionality of the following APIs:
- Address Validation API
- Directions API
- Distance Matrix API
- Elevation API
- Geocoding API
- Places API
- Roads API
- Time Zone API
In addition to the functionality provided by these APIs, the client libraries make some common tasks a little easier.
- Automatic Rate Limiting By default, requests are sent at the expected
rate limit for each web service. You can provide custom QPM limits with
new GeoApiContext().setQueryRateLimit(qpm). - Retry on Failure The client libraries will automatically retry any
request if the API sends a
5xxerror. Retries use exponential back-off, which helps in the event of intermittent failures. - Easy Authentication The client libraries make it easy to authenticate with your freely available API Key. Google Maps Platform Premium Plan customers can use their client ID and secret.
- POJOs The Java libraries return native objects for each of the API responses. The Python libraries return the structure as it is received from the API.
- Asynchronous or synchronous All requests support synchronous or asynchronous calling style.

API keys and client IDs
Each Google Maps web service requires an API key or client ID. For a guide on when to use an API key, when to use a client ID, and how to get hold of your API key or client ID, see the authentication guide for the API you're using:
