---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
payload |
Event#payload | Any data to store with the item.
In addition to the standardized properties described below, you may
include other custom properties that are useful to your specific use case
or plug-in as well. Note that the payload may be an Object or an Array.
In order to group multiple entries to be added, include an Array as the payload.
In that case, each array element will represent a single item and its associated
data. If you would like to group multiple items this way, the payload properties
documented here apply to each object in the array.

remove
Removes one or more items from the system. This event is triggered before the item(s)

event handlers can return the subset of item IDs to remove. This means that another way
to prevent all items from being removed is to return an empty array.
