Hi,
1. event: event means the name of your event, forsay "buy", "view" ,
"rate", "like". (It's not a model name)
2. entityType is always user, since the event corresponds to a user's
event.
3. EntityId correspond to a user ID.
4. properties can vary, for example I might pass a category id of a
particular purchase event, or something like that.
A basic event would look something like this:
{"entityId":"User1","entityType":"user","event":"buy","targetEntityType":"item","targetEntityId":"Product1"}
{"entityId":"User2","entityType":"user","event":"buy","targetEntityType":"item","targetEntityId":"Product2"}
{"entityId":"User3","entityType":"user","event":"view","targetEntityType":"item","targetEntityId":"Product5"}
I hope this helps
