  "_comment": "OUTPUT - webhook, Luminetric-Event: request.failed. Sent to the same registered URL as statements, under the same signature, when a request produces NO statement. Before this existed a client's only way to learn an invoice had died was to notice its absence. The client gets a closed reason code and a fixed sentence - never our exception text, which stays in canonical_failures.internal_message. customer_action_required has the meaning it has on the account resource in 04: is there anything the CLIENT can do. client_reference is the request's own, echoed when the request supplied one and omitted when it did not - a failure early enough to precede reading the request has none to echo. NOT TERMINAL: failed requests are triaged and re-run, and a later statement.available carrying the same request_id supersedes this event. Built by CanonicalFailure.body(); CanonicalDeliveryLocalTest holds that method to this file's shape.",
