The current payload being sent for time entry deletion events doesn't include the "history_items" property, so it doesn't contain the details about the entity being deleted nor the user who performed the deletion.

Would it be possibile to normalize this event payload to match the created/updated event payloads?

Off topic: another nice thing would be to have a "discriminator" property in the payload that tells in a "machine-like manner" which is the action (create, update, delete) that caused the event. At the moment, there's the "data.description" property which reports a human readable description of the action, but that is, indeed, for humas.

Proposal: add a property "action" to the root object, valued with "CREATE", "UPDATE", "DELETE" strings.
