Improve discount representation in the Orders API
Currently, discounts are not consistently represented in the Orders API response.
Guest-applied promo codes are returned in rent.discount, while other promotions, such as Early Bird and Last Minute discounts, are represented as negative line items under fees.otherFees.
As a result, rent.discount can be null even when a reservation has discounts applied.
Requested improvement
Provide a consistent way to identify all discounts in the Order response, regardless of their type or how they are applied.
Ideally, discounts should have a dedicated field or a clear classification in the fee breakdown, allowing partners to identify and reconcile them without additional assumptions.
