Attio

Access the Attio REST API with managed OAuth authentication. Manage CRM objects, records, tasks, notes, comments, lists, list entries, meetings, call recordings, and workspace data.

Quick Start

# List all objects in workspace
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/attio/v2/objects')
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://api.maton.ai/attio/{native-api-path}

Maton proxies requests to api.attio.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 Attio OAuth connections at https://api.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=attio&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': 'attio'}).encode()
req = urllib.request.Request('https://api.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://api.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": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-06T03:13:17.061608Z",
    "last_updated_time": "2026-02-06T03:13:17.061617Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "attio",
    "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://api.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 Attio connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/attio/v2/objects')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always include this header to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to CRM data including people, companies, and custom objects within the connected Attio account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

GET /attio/v2/tasks?limit=50&offset=50
GET /attio/v2/tasks?limit=50&offset=100

Cursor-Based Pagination (for some endpoints)

GET /attio/v2/meetings?limit=50
GET /attio/v2/meetings?limit=50&cursor={next_cursor}

Response includes pagination.next_cursor when more results exist.

Code Examples

JavaScript

// Query company records
const response = await fetch(
  'https://api.maton.ai/attio/v2/objects/companies/records/query',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ limit: 10 })
  }
);
const data = await response.json();

Python

import os
import requests

# Query company records
response = requests.post(
    'https://api.maton.ai/attio/v2/objects/companies/records/query',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={'limit': 10}
)
data = response.json()

Usage Notes

• Object slugs are lowercase snake_case (e.g., people, companies)
• Record IDs and other IDs are UUIDs
• For personal-name attributes, always include full_name when creating records
• Task creation requires format: "plaintext", deadline_at, assignees array (can be empty), and linked_records array (can be empty)
• Note creation requires format, content, parent_object, and parent_record_id
• Comment creation requires format, content, author, plus one of record, entry, or thread_id
• Meetings use cursor-based pagination
• Some endpoints require additional OAuth scopes (lists, notes, webhooks)
• Rate limits: 100 read requests/second, 25 write requests/second
• Pagination uses limit and offset parameters (or cursor for meetings)
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets 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

Error Handling

Status	Meaning
400	Missing Attio connection or validation error
401	Invalid or missing Maton API key
403	Insufficient OAuth scopes
404	Resource not found
429	Rate limited
4xx/5xx	Passthrough error from Attio API

Troubleshooting: API Key Issues

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://api.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: Insufficient Scopes

If you receive a 403 error about missing scopes, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case.

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with attio. For example:

• Correct: https://api.maton.ai/attio/v2/objects
• Incorrect: https://api.maton.ai/v2/objects
