Monday

Monday.com

Access the Monday.com API with managed OAuth authentication. Manage boards, items, columns, groups, users, and workspaces using GraphQL.

Quick Start

# Get current user
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': '{ me { id name email } }'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/monday/v2', 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

Base URL

https://gateway.maton.ai/monday/v2

All requests use POST to the GraphQL endpoint. The gateway proxies requests to api.monday.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

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

Connection Management

Manage your Monday.com 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/{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 Monday.com connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': '{ me { id name } }'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/monday/v2', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', 'ca93f2c5-5126-4360-b293-4f05f7bb6c8c')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Pagination

Response includes cursor when more items exist (null when no more pages):

{
  "data": {
    "boards": [{
      "items_page": {
        "cursor": "MSw5NzI4...",
        "items": [...]

Code Examples

JavaScript

const response = await fetch('https://gateway.maton.ai/monday/v2', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    query: `{ boards(limit: 10) { id name items_page(limit: 20) { items { id name } } } }`
  })
});
const data = await response.json();

Python

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/monday/v2',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'query': '{ boards(limit: 10) { id name items_page(limit: 20) { items { id name } } } }'
    }
)
data = response.json()

Notes

• Monday.com uses GraphQL exclusively (no REST API)
• Board IDs, item IDs, and user IDs are numeric strings
• Column IDs are alphanumeric strings (e.g., color_mm09e48w)
• Group IDs are alphanumeric strings (e.g., group_mm0939df, topics)
• Column values must be passed as JSON strings when creating/updating items
• The account query may require additional OAuth scopes. If you receive a scope error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case
• Board kinds: public, private, share
• Board states: active, archived, deleted, all
• Each cursor is valid for 60 minutes after the initial request
• Default limit is 25, maximum is 100 for most queries

Error Handling

GraphQL errors are returned in the errors array:

{
  "data": {},
  "errors": [
    {
      "message": "Unauthorized field or type",
      "path": ["account"],
      "extensions": { "code": "UNAUTHORIZED_FIELD_OR_TYPE" }
    }
  ]
}

Troubleshooting: Invalid API Key

When you receive a "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. 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
