Figma Reference Architecture

Overview

Production-ready architecture for Figma REST API integrations. Covers the three most common use cases: design token pipelines, asset export systems, and webhook-driven automation.

Prerequisites

Understanding of Figma REST API endpoints
TypeScript project setup
Decision on deployment platform

Client	403 Forbidden	Alert on token expiry; fail gracefully
Cache	Cache miss storm	Stale-while-revalidate pattern
Webhook	Duplicate events	Idempotency via event timestamp
Export	Image render null	Skip node, log warning
