Canva Skill

Create, export, and manage Canva designs via the Connect API.

When to Use

• "Create an Instagram post about [topic]"
• "Export my Canva design as PNG"
• "List my recent designs"
• "Create a carousel from these points"
• "Upload this image to Canva"

Prerequisites

1. Create a Canva Integration:

   • Go to https://www.canva.com/developers/
   • Create a new integration
   • Get your Client ID and Client Secret

2. Set Environment Variables:

   export CANVA_CLIENT_ID="your_client_id"
   export CANVA_CLIENT_SECRET="your_client_secret"
   

3. Authenticate (first time): Run the auth flow to get access tokens (stored in ~/.canva/tokens.json)

API Base URL

https://api.canva.com/rest/v1

Authentication

Canva uses OAuth 2.0. The skill handles token refresh automatically.

# Get access token (stored in ~/.canva/tokens.json)
ACCESS_TOKEN=$(cat ~/.canva/tokens.json | jq -r '.access_token')

Core Operations

    }
  }'

  -H "Content-Type: application/json" \
  -d '{
    "design_id": "DESIGN_ID",
    "format": {"type": "png", "width": 1080, "height": 1080}
  }'

Common Workflows

Create Instagram Post

2. Find Instagram post template
3. Autofill with content: POST /autofills
4. Export as PNG 1080x1080: POST /exports
5. Download the exported file

Create Carousel

1. Create multiple designs using autofill
2. Export each as PNG
3. Combine for posting

Batch Export

2. Loop through and export each
3. Download all files

Rate Limits

• Most endpoints: 100 requests/minute
• Upload/Export: 30 requests/minute

Error Handling

Common errors:

• 401 - Token expired, refresh needed
• 403 - Missing required scope
• 429 - Rate limit exceeded
• 404 - Design/template not found

Scopes Required

• design:content:read - Read designs
• design:content:write - Create/modify designs
• asset:read - Read assets
• asset:write - Upload assets
• brandtemplate:content:read - Read brand templates

Tips

1. Use Brand Templates - Pre-designed templates are faster than creating from scratch
2. Batch Operations - Group exports to avoid rate limits
3. Cache Template IDs - Store commonly used template IDs locally
4. Check Job Status - Exports are async; poll until complete
