About ZIO Webhooks

A microlibrary for reliable and persistent webhook delivery.

Below is a state diagram for each webhook handled by a server. Note that there aren't any initial or final states as the server doesn't manage the entire lifecycle of webhooks and events—only the subset needed for reliable webhook delivery.
