description	Implement reliability patterns for Canva Connect API — circuit breakers, idempotency, graceful degradation. Use when building fault-tolerant Canva integrations, implementing retry strategies, or adding resilience to production Canva services. Trigger with phrases like "canva reliability", "canva circuit breaker", "canva resilience", "canva fallback", "canva fault tolerance".

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
  }
);

canvaBreaker.on('open', () => {
  console.warn('[canva] Circuit OPEN — Canva API unreachable, failing fast');
});

canvaBreaker.on('halfOpen', () => {
  console.info('[canva] Circuit HALF-OPEN — testing Canva recovery');
});

canvaBreaker.on('close', () => {
  console.info('[canva] Circuit CLOSED — Canva API recovered');
});


  () {
   canvaBreaker.( () => {
     (, token, {
      : ,
      : .(body),
    });
  });
}
