     Specifies an array of intermediate locations to include along the route between the origin and destination points as pass through or stopover locations. Waypoints alter a route by directing it through the specified location(s). The API supports waypoints for these travel modes: driving, walking and bicycling; not transit.   You can supply one or more locations separated by the pipe character (`|` or `%7C`), in the form of a place ID, an address, or latitude/longitude coordinates. By default, the Directions service calculates a route using the waypoints in the order they are given. The precedence for parsing the value of the waypoint is place ID, latitude/longitude coordinates, then address.
