# Canva Load & Scale ## Overview Load test and scale Canva Connect API integrations. Since Canva enforces per-user rate limits, scaling means distributing load across users, not increasing per-user throughput. ## Canva Rate Limit Constraints | Operation | Per-User Limit | Implication | |-----------|---------------|-------------| | Create design | 20/min | Max 1,200 designs/hr per user | | List designs | 100/min | Generous for reads | | Create export | 75/5min (500/24hr) | Max 500 exports/day per user | | Integration export | 750/5min (5,000/24hr) | Shared across all users | | Upload asset | 30/min | Max 1,800/hr per user | | Autofill | 60/min | Max 3,600/hr per user | **Key insight:** The integration-wide export limit of 5,000/day across ALL users is the most constraining for high-volume scenarios. ## k6 Load Test ```javascript // canva-load-test.js import http from 'k6/http'; import { check, sleep } from 'k6'; import { Rate, Trend } from 'k6/metrics'; const errorRate = new Rate('canva_error_rate'); const exportDuration = new Trend('canva_export_duration'); export const options = { scenarios: { design_operations: { executor: 'ramping-vus', startVUs: 1, stages: [ { duration: '1m', target: 5 }, // Ramp up slowly { duration: '3m', target: 5 }, // Steady state { duration: '1m', target: 10 }, // Test rate limits { duration: '3m', target: 10 }, // Sustained load { duration: '1m', target: 0 }, // R...
