-# Create a new task
-curl -ikx http://127.0.0.1:8000 https://api.tasks.local/tasks -H "x-api-key: dev-proxy-demo-key" -H "Content-Type: application/json" -d '{"id": 6, "title": "New task", "description": "Task description", "status": "pending", "priority": "high"}'

-curl -ikx http://127.0.0.1:8000 https://api.tasks.local/tasks/1 -X DELETE -H "x-api-key: dev-proxy-demo-key"
