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:

Check required scope in the Scopes Reference
Enable the scope in your integration settings at canva.dev
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

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}: ${await res.text()}`);
  return res.json();
}

# 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'

{ "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

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

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`

# 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	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
