Ulyses Connections allows third parties to complete the payment of the room's pending amount regardless of the time when this is done. In other words, if a reservation's total amount is worth 100€, customers will be able to pay in the reservation at any time and Ulyses Connections will always let third parties know about the updated reservation's amount. This means that they can add a payment of 100€ before checking in or more when they are in-house. This operation is often needed by guest apps or kiosks solutions that invite customers to pay the entire reservation when checking in or when they access the appwhile they're in-house. To complete this operation you need to follow this endpoint.
