Design an Idiomatic REST + Webhooks API for a Logistics SaaS

FreeVerified credential3 weeksAdvanced

Overview

What this challenge is about.

Design a REST + webhooks API guideline and OpenAPI 3.1 spec for a logistics SaaS, then earn a verifiable certificate.

The scenario

The SaaS (Series-B at EUR 40M raised, 4 major terminal customers in EU + Singapore) plans to onboard 25 customs-broker integrators in Q3 — a messy API would burn the integration team for years.

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.

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
