You can think of it as a shopping cart that is pending checkout. It is used to evaluate [Redemption Ceiling Rules](/build/redemption-ceiling-rules). ### Processing Presales are typically fed to Fielo from an external system of record via API. When a presale is registered into Fielo, it enters a queue which is cleared on a first-in, first-out basis. The presale is evaluated against the redemption ceiling rules of the program to which the customer belongs and the redemption ceiling is calculated. ### Attributes For small-scale testing purposes, presales can be created from the Presales page. Presales have all of the attributes that [Sales](/run/sales) have, plus the following additional one: * *Redemption Ceiling Amount*: The maximum amount of currency applicable, should the presale be finalized as a sale. ### Redemption Ceiling Results Post-processing, you have visibility on how a presale was processed by Fielo. Redemption ceiling results show which rule prevailed and which were discarded, including the reasons. You can find the results on the detail page of a processed presale. Redemptionceilingresults Pn ### Statuses Presales can be in one of four statuses: * *Pending-Ready to Process*: The presale has entered the system and is waiting to be processed. * *Pending-Processing*: The presale is being processed against the redemption ceiling rules of the member's program. * *Resolved-Processed*: The presale has been successfully processed against the redemption ceiling rules of the member's program. * *Resolved-Withdrawn*: Presale processing was aborted either because the associated member's status is not *Open-Active* or due to a system error.
