Part 5: After the Dispatch - Handling Delivery Events

说明与用途

实现了从多通信提供商捕获、存储并显示交付事件的工作流程。

问题

Capturing and storing delivery events from multiple communication providers to provide visibility to support, engineering, and customers.

结果

Implemented end-to-end delivery event handling, enabling persistent tracking of message status across providers and a buyer-facing messages interface.

工作流

• 1. Resolve buyer’s verified addresses and select first available channel.
• 2. Dispatch message via Transmitly; provider returns message id and OnDispatched report is raised.
• 3. Provider sends status change webhook; Transmitly converts to OnStatusChanged report.
• 4. DeliveryReportHandler queues reports.
• 5. Background service processes queue, records each report using DeliveryReportRecorder.
• 6. Delivery history stored in communicationsdb with CommunicationRecord and DeliveryEvent tables.
• 7. Buyer can view messages and statuses on new Messages page.

A background service reads the queue and records one report at a time:
