Milestone events push to your customers' systems as they happen — signed, timestamped, retried.
An ERP that keeps its data to itself makes every customer integration a CSV emailed monthly. The forwarders winning the big accounts are the ones whose systems talk.
Every webhook carries a signature and timestamp header; the verification recipe is on the endpoint screen, not in a PDF nobody has.
The signing key appears exactly once, in a panel that will not dismiss itself. Rotation is explicit and immediate.
Events are the milestone vocabulary plus operational events — a stable contract, not whatever shipped last sprint.
Every attempt, response code and retry is on the endpoint's screen. "Did it fire?" has an answer.
