Creating a deferred payment with PayPal
This delay before capture by PayPal can be defined in the payment form via the vads_capture_delay parameter.
In case of a deferred payment, the capture delay is strictly greater than 0. Similarly to payments by card, the results are different if the capture delay is greater than the authorization validity period. For PayPal payments, authorizations are valid for only three days (and not 6 days like for bank card payments).
If the capture delay is less or equal to 3 days:
An authorization is made on the payment day.
The capture will be made on the day of the requested presentation date.
If the capture delay is greater than 3 days:
On the payment day, an operation similar to a card pre-authorization is made.
The authorization will be made 3 days before the requested presentation date. The capture is always made on the day of the presentation date.
