Delivery reliability, limits, billing, and debugging

Timeout, connection failure, and HTTP 5xx are transient. They retry with deterministic jitter around 1 minute, 5 minutes, 30 minutes, 2 hours, then 8 hours, with a hard five-attempt cap; exhaustion becomes dead. HTTP 4xx and redirects are permanent and become failed immediately. HTTP 410 Gone disables the endpoint. Twenty consecutive failures change it to auto_disabled and notify the owner. Disabling an endpoint terminalizes its queued and in-flight deliveries. Canonical delivery statuses are queued, delivering, delivered, failed, dead, and acked for Pull.

Enqueue uses a per-endpoint 60-per-minute token bucket and a per-owner 1,000-per-UTC-day quota. Direct Agent sends and Workflow delivery steps share both quotas. The Redis decision fails closed; rejected calls are not charged. A serialized service payload may be at most 256 KiB. The 64 KiB total argument envelope applies specifically to the direct arinova.delivery.send Action; a Workflow step does not go through that Action, though its graph and rendered payload have their own bounds. Upload oversized data elsewhere and send a link. Enqueue success charges credit immediately. Current runtime does not automatically refund a later failed or dead delivery. Terminal history is retained for 30 days.

Start debugging with the action’s typed error. resource_not_found means the endpoint is absent or not granted to this Agent; it intentionally does not reveal which. resource_conflict means it is not active; ask the owner to verify or enable it in Office > Outgoing Deliveries. permission_denied includes top-up guidance, rate_limited includes retry details, and invalid_arguments covers event format or size. Then ask the owner to inspect delivery history and the endpoint failure count; never infer delivery from queued. Delivery history intentionally retains no payload, and Workflow run detail stores only contentBytes, so neither surface can recover sent content later.
