Canva Common Errors

Overview

Quick reference for the most common Canva Connect API errors at api.canva.com/rest/v1/* with real HTTP status codes, error payloads, and fixes.

Error Reference

401 Unauthorized — Token Expired or Invalid

{ "error": "invalid_token", "message": "The access token is invalid or expired" }

Cause: Access tokens expire after ~4 hours. Token may be malformed or revoked.

Fix:

// Refresh the token
const res = await fetch('https://api.canva.com/rest/v1/oauth/token', {
  method: 'POST',
  headers: {
    'Authorization': `Basic ${Buffer.from(`${clientId}:${clientSecret}`).toString('base64')}`,
    'Content-Type': 'application/x-www-form-urlencoded',
  },
  body: new URLSearchParams({
    grant_type: 'refresh_token',
    refresh_token: storedRefreshToken,
  }),
});
const { access_token, refresh_token } = await res.json();
// IMPORTANT: Each refresh token is single-use — store the new one

---

403 Forbidden — Missing Scope or Insufficient Permissions

{ "error": "insufficient_scope", "message": "Required scope: design:content:write" }

Cause: Your integration doesn't have the required OAuth scope enabled, or the user isn't authorized for the resource.

Fix:

1. Check required scope in the Scopes Reference
2. Enable the scope in your integration settings at canva.dev
3. Re-authorize the user — existing tokens don't gain new scopes retroactively

---

429 Too Many Requests — Rate Limited

{ "error": "rate_limit_exceeded", "message": "Rate limit exceeded" }

Cause: Exceeded per-endpoint rate limits. Key limits:

Endpoint	Limit
GET /v1/users/me	10 req/min
POST /v1/designs	20 req/min
GET /v1/designs	100 req/min
POST /v1/exports	75 req/5min, 500/24hr (per user)
POST /v1/asset-uploads	30 req/min
POST /v1/autofills	60 req/min
POST /v1/folders	20 req/min

Fix:

async function canvaAPIWithRetry(path: string, token: string, opts: RequestInit = {}) {
  const res = await fetch(`https://api.canva.com/rest/v1${path}`, {
    ...opts,
    headers: { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json', ...opts.headers },
  });

  if (res.status === 429) {
    const retryAfter = parseInt(res.headers.get('Retry-After') || '60');
    console.warn(`Rate limited — waiting ${retryAfter}s`);
    await new Promise(r => setTimeout(r, retryAfter * 1000));
    return canvaAPIWithRetry(path, token, opts); // Retry once
  }

  if (!res.ok) throw new Error(`Canva ${res.status}: ${ res.text()}`);
   res.();
}

---

404 Not Found — Resource Missing

Cause: Design, asset, template, or folder ID doesn't exist, was deleted, or the user doesn't have access.

Fix:

# Verify the resource exists — check design ID
curl -s -H "Authorization: Bearer $TOKEN" \
  https://api.canva.com/rest/v1/designs/$DESIGN_ID | jq '.design.id'

---

400 Bad Request — Validation Error

Common cases:

{ "error": "validation_error", "message": "Design title invalid" }

Field	Constraint
title	1-255 characters
design_type.width	40-8000 pixels
design_type.height	40-8000 pixels
format.quality (JPG)	1-100
format.width/height (export)	40-25000 pixels
Chart data	Max 100 rows, 20 columns

---

Export Error Codes

Code	Meaning	Solution
license_required	Design uses premium elements	User needs Canva Pro subscription
approval_required	Design pending approval	User must approve in Canva
internal_failure	Canva server error	Retry after delay

---

OAuth Error Codes

Code	Meaning	Solution
invalid_client	Wrong client_id or secret	Check credentials
invalid_grant	Auth code expired/reused	Restart OAuth flow
invalid_scope	Scope not enabled	Enable in integration settings
unsupported_grant_type	Wrong grant_type	Use authorization_code or refresh_token

Quick Diagnostic Commands

# Check your token
curl -s -H "Authorization: Bearer $TOKEN" \
  https://api.canva.com/rest/v1/users/me | jq

# Check API connectivity
curl -sI https://api.canva.com/rest/v1/users/me \
  -H "Authorization: Bearer $TOKEN" 2>&1 | head -5

# Verify environment variables
echo "Client ID: ${CANVA_CLIENT_ID:+[SET]}"
echo "Access Token: ${CANVA_ACCESS_TOKEN:+[SET]}"

Error Handling

Error	Cause	Solution
ENOTFOUND	DNS failure	Check network connectivity
ETIMEDOUT	Network timeout	Increase timeout, check firewall
invalid_token	Expired access token	Refresh via OAuth endpoint
insufficient_scope	Missing permission	Enable scope, re-authorize
