Note 1: the date property on an event is optional and if left off UTC time will be used in its place.

Note 2: In versions prior to v5, the /users/events endpoint would prepend Public Api: to events when viewed in the web view. In v5, this behavior has been removed, but if your code depends on this, then you can use the /v4/users/events/ endpoint.

Note 3: POSTing an event to a user with multiple devices will cause the event to be attributed to each and every device associated with the requested user_id.

Dates should be formatted using an ISO 6801 formatted string.
