I'd like to store a Paypal transaction for a long term authorization (greater than 28 days) to be finally captured when an item ships. (That way, there's no risk as no money has exchanged hands at that point.) It's easy to do with credit cards by indefinitely storing the credit card via the vault and charging it when the time comes, but is there a method to indefinitely store a Paypal account to be charged when the time comes?
Right now, the only way I see that possible is through Preapproval in the Adaptive Payments API, but is there a method to do the same in the RESTful API? If not, is it planned? Is/will it be exactly like the current Preapproval API where it might fail because it uses the exact funding source or will it be more guaranteed? (I understand if a credit card is full, or user deletes their Paypal account, but that should be a very rare event.)
More Info: The full amount is known to the consumer in advance, the general timeframe is known to the consumer in advance but not the exact date, the event or item could be cancelled so authorizations could be voided (therefore no money ever exchanges hands), and the money will go directly to me and not in escrow or chained with any other Paypal account.
