Amend a Reservation
This endpoint allows you to amend certain details of an existing reservation.
Important notes:
Changing the pickup or return station is not accepted. If you wish to change the station, you must cancel the current reservation and create a new one.
If you change the pickup/return dates, vehicle group preference, customer age, or mileage policy, the system will internally call the availability service. This may result in:
No availability for the new criteria (the amendment will fail with an error)
A change in the rate/price of the order (the new rate will be applied)
If the availability service is called due to such changes, the amended order will be set to pending status. You must then commit the order to finalize the reservation.
If only non-critical fields are changed (e.g., notes, flight number), the order remains in its current status.
Please review the response for any required follow-up actions after amending a reservation.
