+### Example with Python
+
+Here a basic example written in Python to create a task:
+
+```python
+#!/usr/bin/env python
+
+import requests
+import json
+
+def main():
+    url = "http://demo.kanboard.net/jsonrpc.php"
+    api_key = "be4271664ca8169d32af49d8e1ec854edb0290bc3588a2e356275eab9505"
+    headers = {"content-type": "application/json"}
+
+    payload = {
+        "method": "createTask",
+        "params": {
+            "title": "Python API test",
+            "project_id": 1
+        },
+        "jsonrpc": "2.0",
+        "id": 1,
+    }
+
+    response = requests.post(
+        url,
+        data=json.dumps(payload),
+        headers=headers,
+        auth=("jsonrpc", api_key)
+    )
+
+    if response.status_code == 401:
+        print "Authentication failed"
+    else:
+        result = response.json()
+
+        assert result["result"] == True
+        assert result["jsonrpc"]
+        assert result["id"] == 1
+
+        print "Task created successfully!"
+
+if __name__ == "__main__":
+    main()
+```
+
+Run this script from your terminal:
+
+```bash
+python jsonrpc.py
+Task created successfully!
+```
