Deposit reached a terminal or notable state. Deliveries for the same payment are ordered. Sent as POST to the URL registered for this partner, with Authorization: Basic <secret> carrying the registered secret verbatim. Registration is done through the Telegram bot, not through this API. Respond within 15 seconds. A failed delivery is not retried, except the refund announcement, which a durable job redelivers (Webhooks). Reconcile with GET /deposits rather than waiting for a second attempt, and still deduplicate on qrId.
