Canva Production Checklist Skill

Canva Production Checklist

Overview

Complete checklist for deploying Canva Connect API integrations to production, covering OAuth configuration, security, error handling, monitoring, and Canva's integration review process.

Pre-Deployment

OAuth & Security

[ ] Client ID and secret stored in secret manager (not env files)
[ ] Redirect URIs use HTTPS and match production domains
[ ] Only required OAuth scopes requested (least privilege)
[ ] Access tokens stored encrypted at rest
[ ] Refresh token rotation handled (single-use tokens)
[ ] Token revocation implemented for user disconnect
[ ] No client secrets in frontend code

API Integration

[ ] All API calls use api.canva.com/rest/v1/* endpoints
[ ] Rate limits respected with exponential backoff (see canva-rate-limits)
[ ] Export polling implemented with timeout (don't poll forever)
[ ] 429 responses handled with Retry-After header
[ ] 401 responses trigger automatic token refresh
[ ] Error responses parsed and logged (without tokens)
[ ] Blank designs auto-delete warning handled (7-day window)
[ ] Export download URLs consumed within 24-hour window

Webhook Security

[ ] Webhook endpoint uses HTTPS
[ ] JWK signature verification implemented (see canva-webhooks-events)
[ ] Webhook handler returns 200 immediately
[ ] Heavy processing done asynchronously
[ ] Idempotency keys prevent duplicate processing

Data Handling

[ ] No access tokens in log output
[ ] User design metadata treated as sensitive
[ ] Temporary URLs (thumbnails, exports) not cached beyond expiry
[ ] Thumbnail URLs expire in 15 minutes — refresh as needed
[ ] Edit/view URLs expire in 30 days — regenerate via API

Production Readiness Verification

#!/bin/bash
# canva-prod-verify.sh

echo "=== Canva Production Readiness ==="

# 1. Verify API connectivity from production
HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $CANVA_ACCESS_TOKEN" \
  "https://api.canva.com/rest/v1/users/me")
echo "[$([ $HTTP_CODE = 200 ] && echo 'PASS' || echo 'FAIL')] API connectivity: HTTP $HTTP_CODE"

# 2. Test design creation
DESIGN=$(curl -s -X POST "https://api.canva.com/rest/v1/designs" \
  -H "Authorization: Bearer $CANVA_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"design_type":{"type":"custom","width":100,"height":100},"title":"Prod Test"}')
DESIGN_ID=$(echo "$DESIGN" | python3 -c "import sys,json; print(json.load(sys.stdin)['design']['id'])" 2>/dev/null)
echo "[$([ -n "$DESIGN_ID" ] && echo 'PASS' || echo 'FAIL')] Design creation: $DESIGN_ID"

# 3. Test export
if [ -n "$DESIGN_ID" ]; then
  EXPORT=$(curl -s -X POST "https://api.canva.com/rest/v1/exports" \
    -H "Authorization: Bearer $CANVA_ACCESS_TOKEN" \
    -H "Content-Type: application/json" \
    -d "{\"design_id\":\"$DESIGN_ID\",\"format\":{\"type\":\"png\"}}")
  EXPORT_ID=$(echo "$EXPORT" | python3 -c "import sys,json; print(json.load(sys.stdin)['job']['id'])" 2>/dev/null)
  echo "[$([ -n "$EXPORT_ID" ] && echo 'PASS' || echo 'FAIL')] Export job: $EXPORT_ID"
fi

echo ""
echo "=== Done ==="

Canva Integration Review

For public integrations (available to all Canva users), you must pass Canva's review:

Submit your integration for review in the Canva developer portal
Canva reviews security, OAuth implementation, and UX
Preview features (e.g., webhooks) are not allowed in public integrations
Fix any issues and resubmit

Private integrations (your organization only) do not require review.

Health Check Endpoint

app.get('/health', async (req, res) => {
  const start = Date.now();
  let canvaStatus = 'unknown';

  try {
    const me = await fetch('https://api.canva.com/rest/v1/users/me', {
      headers: { 'Authorization': `Bearer ${getServiceToken()}` },
      signal: AbortSignal.timeout(5000),
    });
    canvaStatus = me.ok ? 'healthy' : `error:${me.status}`;
  } catch {
    canvaStatus = 'unreachable';
  }

  res.json({
    status: canvaStatus === 'healthy' ? 'healthy' : 'degraded',
    services: { canva: { status: canvaStatus, latencyMs: Date.now() - start } },
    timestamp: new Date().toISOString(),
  });
});

Monitoring Alerts

| Alert | Condition | Severity | |-------|-----------|----------| | Auth failures | 401 errors > 0 | P1 | | Rate limited | 429 errors > 5/min | P2 | | Export failures | license_required or internal_failure | P3 | | API unreachable | Connection timeout | P1 | | Token refresh fails | Refresh returns error | P1 |

Error Handling

| Issue | Cause | Solution | |-------|-------|----------| | Token refresh loop | Revoked refresh token | Re-authorize user | | Export stuck in_progress | Backend delay | Timeout after 120s, retry | | Webhook URL rejected | HTTP not HTTPS | Use HTTPS endpoint | | Review rejection | Using preview features | Remove preview-only features |
