USPS API Integration & Tracking with ClickPost

ClickPost automatically detects exceptions such as delayed transit, failed delivery attempts, or other delivery issues. Its exception management and NDR (Non-Delivery Report) suite classifies such orders in the same group, triggers automated alerts to customers and operations teams, and helps you initiate the next best action (e.g., reschedule delivery or connect with USPS).

ClickPost’s analytics reports provide detailed insights into USPS delivery performance, including carrier performance trends, SLA adherence, transit times, exceptions, etc. Brands can download 50+ customizable reports on metrics such as delivery success rates, delivery speed, and more to know whether USPS is truly a valuable investment or not.

ClickPost offers an API integration that connects with USPS. Businesses can integrate USPS with ClickPost and go-live within 24 hours. This gives you key information directly from the carrier’s main network like tracking, order status, etc.
