Payout due
A billing window became due, as the Due tab shows it (windows with nothing to pay are left out). Reported in a morning pass at around 06:40 in the campaign's zone, once the window's views have closed (views count by UTC day, so a period's views close at the end of the UTC day its last instant falls on): the morning after the close, or, east of about UTC+6:40, where they close later in the morning, right after the close. A window that becomes due again (after a withdrawal or a reinstatement) comes with a higher generation. Windows already due when you subscribed are not reported; GET /payouts/due lists them.

Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
