1524523204.000192Usage info
This method returns a list of all reactions for a single item (file, file comment, channel message, group message, or direct message).
Response
An item will always have a type property, while the other properties depend on the type of item. The possible types are:
message: the item will have amessageproperty containing a message object and achannelproperty containing the channel ID for the messagefile: this item will have afileproperty containing a file objectfile_comment: the item will have afileproperty containing the file object and acommentproperty containing the file comment
The users array in the reactions property will always contain the authenticated user, but might not always contain all users that have reacted. The value of count, however, will always represent the count of all users who made that reaction (i.e. it may be greater than users.length).
The response contains the item with reactions.
