Design an Idiomatic REST + Webhooks API for a Logistics SaaS
Overview
What this challenge is about.
Design an Idiomatic REST + Webhooks API for a Logistics SaaS. Advanced challenge in design. Designing real products under real constraints, earn a blockchain...
The Brief
What you'll do, and what you'll demonstrate.
Author an API design guideline, redesign 12 resources, and design a production-grade webhook subsystem for a logistics SaaS launching a public API.
This is not a design exercise. It is the work a product designer does between a brief and a shipped interface. That distinction matters to every hiring manager who has seen candidates redesign Spotify's homepage and none who have worked under real product constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Author an API guideline that survives the team's first 12 resources
- Design a webhook subsystem with at-least-once + idempotency
- Trade off URL versioning vs header versioning with evidence
- Self-critique a public API before integrators do
