The present application relates to the technical field of cruising taxis and online appointment vehicles, and in particular relates to an order processing method and apparatus, a server and a storage medium. The method includes: receiving an order request sent by a user, the order request including information of a requested vehicle model set by the user; selecting a target vehicle according to the order request so as to send order distribution information; and if the requested vehicle model set by the user is an online appointment vehicle model, sending an operating state change instruction to the target vehicle. According to the order processing method not only avoids the order acceptance and dropping behavior of cruising taxi drivers and ensures that the user may travel conveniently, but also ensures that the vehicle that accepts the order may meet user demands, improving the user experience.
