The Directions API is a web service that uses an HTTP request to return JSON or XML-formatted directions between locations. You can receive directions for several modes of transportation, such as transit, driving, walking, or cycling.
For direction calculations that respond in real time to user input (for example, within a user interface element), you can use the Directions API or, if you're using the Maps JavaScript API, use the Directions service. For server-side use, you can use Java Client, Python Client, Go Client and Node.js Client for Google Maps Services.
