Trello

Access the Trello API with managed OAuth authentication. Manage boards, lists, cards, checklists, labels, and members for project and task management.

Quick Start

              # Get boards for current user
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/trello/1/members/me/boards')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
            

Base URL

https://gateway.maton.ai/trello/{native-api-path}

Replace {native-api-path} with the actual Trello API endpoint path. The gateway proxies requests to api.trello.com and automatically injects your OAuth token.

Authentication

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"

Getting Your API Key

Sign in or create an account at maton.ai
Go to maton.ai/settings
Copy your API key

Connection Management

Manage your Trello OAuth connections at https://ctrl.maton.ai.

List Connections

              python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=trello&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
            

Create Connection

              python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'trello'}).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
            

Get Connection

              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": "trello",
    "metadata": {}
  }
}
            

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

              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
            

Specifying Connection

If you have multiple Trello 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/trello/1/members/me/boards')
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.

Code Examples

JavaScript

              const headers = {
  'Authorization': `Bearer ${process.env.MATON_API_KEY}`
};

// Get boards
const boards = await fetch(
  'https://gateway.maton.ai/trello/1/members/me/boards',
  { headers }
).then(r => r.json());

// Create card
await fetch(
  'https://gateway.maton.ai/trello/1/cards',
  {
    method: 'POST',
    headers: { ...headers, 'Content-Type': 'application/json' },
    body: JSON.stringify({
      name: 'New Task',
      idList: 'LIST_ID',
      desc: 'Task description'
    })
  }
);
            

Python

              import os
import requests

headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}

# Get boards
boards = requests.get(
    'https://gateway.maton.ai/trello/1/members/me/boards',
    headers=headers
).json()

# Create card
response = requests.post(
    'https://gateway.maton.ai/trello/1/cards',
    headers=headers,
    json={
        'name': 'New Task',
        'idList': 'LIST_ID',
        'desc': 'Task description'
    }
)
            

Notes

IDs are 24-character alphanumeric strings
Use me to reference the authenticated user
Dates are in ISO 8601 format
pos can be top, bottom, or a positive number
Card positions within lists are floating point numbers
Use fields parameter to limit returned data and improve performance
Archived items can be retrieved with filter=closed
IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Error Handling

Status	Meaning
400	Missing Trello connection or invalid request
401	Invalid or missing Maton API key
404	Board, list, or card not found
429	Rate limited (10 req/sec per account)
4xx/5xx	Passthrough error from Trello API

Troubleshooting: API Key Issues

Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

Verify the API key is valid by listing connections:

              python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
            

Troubleshooting: Invalid App Name

Ensure your URL path starts with trello. For example:

Correct: https://gateway.maton.ai/trello/1/members/me/boards
Incorrect: https://gateway.maton.ai/1/members/me/boards
