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.
