|Description|| Mandatory parameter used for creating a recurring payment. |
It designates the recurring payment rule to be applied.
The expected value for this parameter is a chain of characters that comply with the iCalendar (Internet Calendar) specification, described in RFC5545 (see http://tools.ietf.org/html/rfc5545).
Among other aspects, this specification allows to define complex recurring payment rules via the RRULE property.
For technical reasons, it is not possible to define recurring payment periods that are shorter than one day.
The keywords " SECONDLY" / "MINUTELY" / "HOURLY " are not taken into account.
Input and output field, returned in the response (IPN and Return URL).
