Message status webhooks: sent, delivered, failed

Linq’s messaging API treats sending as an asynchronous process, so a successful POST response only confirms that a message has been accepted and queued, while webhooks report its eventual outcome through sent, delivered, read, and failed events. The events distinguish network dispatch from confirmed device delivery, provide timestamps for measuring latency, and include actionable failure codes for retries, protocol fallbacks, and list hygiene. Delivery and read receipts depend on the messaging protocol: iMessage and RCS can emit them, while SMS and MMS generally emit only sent or failed, requiring integrations to avoid treating missing delivery events as failures. Production webhook consumers should deduplicate at-least-once deliveries using event IDs, return responses within 10 seconds while processing work asynchronously, handle retries and out-of-order events using event timestamps, verify HMAC signatures, and pin webhook versions to prevent payload changes from breaking integrations. Proper use of these events enables accurate customer-facing status indicators, delivery-rate monitoring, fallback workflows, two-factor authentication tracking, and end-to-end debugging.
