I read the following doc
The duration in traffic is returned only if all of the following are true:
1. The request includes a valid API key, or a valid Google Maps APIs Premium Plan client ID and signature.
2. The request does not include stopover waypoints. If the request includes waypoints, they must be prefixed with via: to avoid stopovers.
3. The request is specifically for driving directions—the mode parameter is set to driving.
4. The request includes a departure_time parameter.
5. Traffic conditions are available for the requested route.
For condition 2, how do I prefix via: to the waypoints. I have a list of coordinates.
