Canva Reliability Patterns

Overview

Production-grade reliability patterns for the Canva Connect API. The API has async operations (exports, uploads, autofills) that can fail or timeout, OAuth tokens that expire every 4 hours, and rate limits that require backoff.

Circuit Breaker

import CircuitBreaker from 'opossum';

const canvaBreaker = new CircuitBreaker(
  async (fn: () => Promise<any>) => fn(),
  {
    timeout: 30000,              // 30s before failure
    errorThresholdPercentage: 50, // Open after 50% failure rate
    resetTimeout: 60000,          // Try again after 60s
    volumeThreshold: 5,           // Min 5 requests before evaluating
  }
);
