Send an email to Carsales for these things:
1- Need confirmation with Carsales. Are there any changes on the JSON file (10 months ago) that they send us?
2- Every dealer will have a published API URL base on that dealer.
E.g. https://porschecentreadelaide.com.au/API/importVehicle
https://porschebrighton.com.au/API/importVehicle
3- Request Carsales for more Vehicle-Json. We need more JSON for testing.
Update from Carsales (21 Jul 21): "Vehicles are sent individually per transaction"
