Reading a pickup response

HERE Waypoints Sequence API v8 has the following basic response structure.

• a waypoints object that lists the optimized waypoint sequence based on the parameters in the request. The value in the element sequence indicates the optimal order.
• not mentioned waypoints are not worth visiting, i.e. would overall cause more detour time/distance cost than they provide revenue.
• information about the total distance and time of your journey
• an interconnections object that includes information about the journey between the indicated waypoints
• information about the kind of optimization and supporting information
• metainformation about your request

Example response structure:
