Latitude longitude between to stops by using trip id

hello everyone I am using this API for real-time vehicle position.
https://api.transport.nsw.gov.au/v1/gtfs/vehiclepos/buses

This API returns vehicle’s origin and destination address with current position (latitude, longitude).

i need to display all stops(bus stop) that are coming between vehicle’s origin and destination

do I need to access some another API for the list of that station?

please help

maybe this one? Public Transport - Timetables - For Realtime - Dataset - TfNSW Open Data Hub and Developer Portal
