# Recover events a webhook endpoint missed

> Queues a delivery for every subscribed event created since `since` that never reached this endpoint, for example while it was disabled, and the next attempt for every event whose attempts to it all failed with no retry pending. Events that reached the endpoint or still have an attempt pending are left alone. `since` is clamped to the endpoint's creation time and must be within the last 30 days. The work runs in batches so a large window never ties up one transaction; a resent event gets one more attempt. Deliveries start within about a minute, in the order the dispatcher's sweep picks them up.

                Stable, namespaced error code. The `ErrorCode` catalogue lists
                every code defined today; handle an unrecognized value as a
                generic failure rather than throwing, since codes are added over
                time.
              example: chip.not_found
            message:
              type: string
              description: >-
                Human-readable description, for logs and debugging. Wording may
                change without notice - never parse or match against it.
