Search and book a car rental via the Rentalcars Connect API

Steps

1. Authenticate with the Rentalcars Connect API using your partner credentials to obtain a session token; the base URL and auth endpoint will be provided in your partner onboarding documentation.
2. Call the vehicle search endpoint with pickup location (IATA airport code or geo coordinates), pickup datetime, dropoff datetime, and driver age; parse the returned list of vehicle categories with their rate codes and supplier codes.
3. Filter results by vehicle category (economy, SUV, etc.), transmission type, and included mileage; present the total price which should include taxes and fees as indicated by the priceBreakdown fields.
4. Initiate a booking by POSTing the selected rate code along with driver details (name, age, license country) and a payment reference; note the reservation confirmation number returned.
5. Store the supplier confirmation code alongside your internal booking ID; the supplier code is what the rental desk uses at pickup and differs from the aggregator reference.
6. Handle cancellation by calling the cancel endpoint with the booking reference before the free-cancellation deadline surfaced in the rate's cancellationPolicy object.
