You can split up a planned card into several new cards within the same collection. The number of resulting cards can be determined with the date_parts array. For each resulting card you can fill a planned date and a time value. This wil result in a new card on the chosen date, with the chosen time estimate.
If you want the resulting cards to be planned in the past, please use the “reverse” key.To understand the difference between collections and cards, please visit our help center.Splitting cards is an asynchronous process, new cards are almost but not instantly created.
