The vads_sub_desc field is a mandatory parameter used in the case of 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). Example To program installment payments taking place on the last day of each month for 12 months, the rule is: vads_sub_desc=RRULE:FREQ=MONTHLY;BYMONTHDAY=28,29,30,31;BYSETPOS=-1;COUNT=12 This rule means that if the current month does not have 31 days, the machine will take the 30th into account. If there is no 30th day in a month, the machine will take the 29th into account, and so on until the 28th. Make sure that the values entered in the form respect the expected format. |
