Telemetry API Design for Autonomous Dispatch
By Dillip Chowdary • July 25, 2026
Low-Latency Data Handoff Protocols
The integration between Waymo’s autonomous fleet management software and Uber’s passenger dispatch platform requires a low-latency API architecture. When a user requests a ride, Uber’s system queries Waymo’s fleet controller via secure REST endpoints to check vehicle availability and estimated arrival times.
To protect passenger safety and optimize routing, the API must share real-time telemetry data, including vehicle location, sensor status, and route adjustments. This data is transmitted using WebSockets to ensure that both platforms have a synchronized view of the trip's progress.

Dispatch State Machine Synchronization
A key component of the integration is the dispatch state machine, which coordinates trip planning and handoffs. The state machine must handle edge cases like passenger delays or vehicle reroutes, communicating status updates between the two systems to ensure a smooth passenger experience.
Security is a major focus for the API architecture, which handles sensitive user data and operational details. The integration implements mutual TLS authentication and strict API rate limiting, protecting the autonomous fleet from unauthorized access while maintaining system availability.
