Prerequisites

Before you begin, make sure you have:
  • A Day Copilot account (sign up here)
  • Your API credentials (JWT token)
  • A tool to make HTTP requests (cURL, Postman, or your favorite programming language)

​
Step 1: Get Your API Token

After signing in to Day Copilot, you’ll receive a JWT token. This token authenticates all your API requests.
Your JWT token is sensitive! Never commit it to version control or share it publicly.

​
Step 2: Make Your First API Call

Let’s fetch your tasks to verify everything is working. 
curl -X GET "https://app.daycopilot.ai/api/v1/tasks" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json"
Replace YOUR_JWT_TOKEN with your actual token from the Day Copilot dashboard.

​
Step 3: Create Your First Task

Now let’s create a new task: 
curl -X POST "https://app.daycopilot.ai/api/v1/tasks" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "My First API Task",
    "description": "Created via the Day Copilot API",
    "priority": "medium",
    "status": "pending"
  }'

​
Step 4: Response Format

Successful requests return a JSON response: 
{
  "data": {
    "id": "550e8400-e29b-41d4-a716-446655440000",
    "title": "My First API Task",
    "description": "Created via the Day Copilot API",
    "priority": "medium",
    "status": "pending",
    "createdAt": "2025-11-02T12:00:00Z",
    "updatedAt": "2025-11-02T12:00:00Z",
    "version_major": 1,
    "version_minor": 1,
    "is_published": true
  }
}

​
