Creating a deferred payment

A deferred payment is a payment debited all at once with a capture delay that is strictly greater than 0 days.

An information request will be made if the capture delay is greater than the validity period of an authorization request (see table).

The information request is made in order to check the card validity. For acquirers who do not support information request, an authorization request for 1 EUR will be made (see table).
