Access the Todoist API v1 with managed OAuth authentication. Manage tasks, projects, sections, labels, and comments.
# List all tasks python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/todoist/api/v1/tasks') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
https://gateway.maton.ai/todoist/api/v1/{resource}
The gateway proxies requests to
api.todoist.com/api/v1 and automatically injects your OAuth token.
All requests require the Maton API key in the Authorization header:
Authorization: Bearer $MATON_API_KEY
Environment Variable: Set your API key as
MATON_API_KEY:
export MATON_API_KEY="YOUR_API_KEY"
Manage your Todoist OAuth connections at
https://ctrl.maton.ai.
python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections?app=todoist&status=ACTIVE') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'todoist'}).encode() req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Content-Type', 'application/json') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
Response:
{ "connection": { "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80", "status": "ACTIVE", "creation_time": "2025-12-08T07:20:53.488460Z", "last_updated_time": "2026-01-31T20:03:32.593153Z", "url": "https://connect.maton.ai/?session_token=...", "app": "todoist", "metadata": {} } }
Open the returned
url in a browser to complete OAuth authorization.
python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
If you have multiple Todoist connections, specify which one to use with the
Maton-Connection header:
python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/todoist/api/v1/tasks') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF
If omitted, the gateway uses the default (oldest) active connection.
