name: clio description: | Clio API integration with managed OAuth. This is a write-capable integration — it can read, create, update, and delete legal practice data including matters, contacts, activities, tasks, documents, calendar entries, time entries, and billing. Use this skill when users want to interact with legal practice data in Clio Manage. All write operations (creating/updating/deleting matters, contacts, billing) require explicit user approval with specific resource identifiers before execution. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 homepage: "https://maton.ai" requires: env: - MATON_API_KEY

Clio

Access the Clio Manage API with managed OAuth authentication. Manage matters, contacts, activities, tasks, documents, calendar entries, time entries, and billing for legal practice management.

Quick Start

# List matters
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/clio/api/v4/matters?fields=id,display_number,description,status')
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/clio/{native-api-path}

The gateway proxies requests to app.clio.com and automatically injects your OAuth token. Only the endpoints documented in this skill are supported — always use specific endpoint paths from the API Reference section below rather than constructing arbitrary paths.

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 Clio 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=clio&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': 'clio'}).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": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "clio",
    "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 Clio 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/clio/api/v4/matters')
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 matters, contacts, activities, tasks, documents, and billing within the connected Clio account. This data is sensitive legal/business information — only install if you trust this integration. Use the narrowest OAuth scopes and Clio account access available, and revoke unused connections promptly.
• Default to read-only operations. Always start by listing or retrieving resources to confirm identifiers before proposing any changes.
• All write operations require explicit user approval with specific identifiers. Before executing any create, update, or delete call:
  1. Retrieve and display the target resource (matter name/ID, contact name, document title) so the user can verify.
  2. Clearly describe the intended effect (e.g., "This will delete matter 'Smith v. Jones' (ID: 12345) and its associated data").
  3. Wait for explicit user confirmation before proceeding.
• High-impact operations require extra caution. Deleting matters, modifying billing records, or changing contact information can affect legal case data. These actions must include a summary of consequences and require confirmation.

Response includes pagination info in the meta object:

{
  "data": [...],
  "meta": {
    "paging": {
      "next": "https://app.clio.com/api/v4/matters?page_token=xyz123"
    },
    "records": 50
  }
}

Use the page_token parameter to fetch the next page:

GET /clio/api/v4/matters?fields=id,description&page_token=xyz123

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/clio/api/v4/matters?fields=id,display_number,description',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/clio/api/v4/matters',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'fields': 'id,display_number,description'}
)
data = response.json()

Notes

• Field selection is important - default responses only include id and etag
• Nested resources use curly bracket syntax: matter{id,description}
• Only one level of nesting is supported
• Contact types: Person or Company
• Task assignees require both id and type ("User" or "Contact")
• Calendar entries require calendar_owner with id and type; associating a matter during creation may fail - use PATCH to link matters after creation
• Activity quantity is in seconds (3600 = 1 hour)
• Contact records limited to 20 email addresses, phone numbers, and addresses each
• Activities, Documents, and Bills endpoints require additional OAuth scopes beyond the basic integration
• 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

Rate Limit Headers

Clio includes rate limit headers in responses:

• X-RateLimit-Limit - Maximum requests in 60-second window
• X-RateLimit-Remaining - Requests remaining in current window
• X-RateLimit-Reset - Unix timestamp for window reset
• Retry-After - Seconds to wait (when throttled)
