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

Replace

{native-api-path}

with the actual Attio API endpoint path. The gateway 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

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

Connection Management

Manage your Attio 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=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://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": "67b77f19-206e-494c-82c2-8668396fc1f1",
    "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://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 Attio 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/attio/v2/objects')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '67b77f19-206e-494c-82c2-8668396fc1f1')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

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://gateway.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://gateway.maton.ai/attio/v2/objects/companies/records/query&#x27;,
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

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: 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

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

Correct:

https://gateway.maton.ai/attio/v2/objects

Incorrect:
```
https://gateway.maton.ai/v2/objects
```
