What this API does:
The Webhook - Delivery Receipts provides delivery status for outbound messages. Whenever a message has a new delivery status, a POST request with the new status is provided to the callback URL.
A connected HVAC system for a medical facility needs to send pre failure alerts to technicians to ensure it maintains a consistent temperature. The HVAC system will automatically send an SMS to the technicians alerting them of an impending issue. There is a logic in place to monitor the delivery status of the SMS alert and use a fallback alerting method if needed. They rely on the delivery status webhook to monitor SMS delivery.
