📖 About This Skill

name: squareup description: | Square API integration with managed OAuth. Install only if you need Square administration. Connect with the least-privileged Square account and OAuth scopes available, verify the intended connection ID before each request, and revoke unused connections promptly. This integration can mutate Square data — approve only specific write actions after checking the exact endpoint, account, resource ID, and consequence. 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: 🧠 requires: env: - MATON_API_KEY

Square

Access the Square API with managed OAuth authentication. See the API Reference below for supported endpoints.

Quick Start

# List locations
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/squareup/v2/locations')
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/squareup/{endpoint-path}

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

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

IMPORTANT: Treat MATON_API_KEY as a secret — do not log it, include it in chats or prompts visible to others, or expose it in shared files or outputs. The key authenticates with Maton, and the Square connection is independently scoped via OAuth. Use least-privileged Square OAuth scopes, revoke unused connections promptly, and if the key is compromised, rotate it immediately at maton.ai/settings.

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 Square 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=squareup&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': 'squareup'}).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": "squareup",
    "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 Square 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/squareup/v2/locations')
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 the Square resources permitted by the connected account's OAuth scopes. Only install if you need Square administration. Use the least-privileged OAuth scopes available and revoke unused connections promptly.

Default to read-only operations. Always start by listing or retrieving resources to confirm account, location, and resource identifiers before proposing any changes.

All write operations require explicit user approval with specific identifiers. Before executing any POST, PUT, or DELETE call:

1. Retrieve and display the target resource (customer name, order ID, catalog item, location) so the user can verify. 2. Clearly describe the intended effect (e.g., "This will process a $50.00 payment at location 'Main Store' (ID: L123) for customer 'John Doe'"). 3. Wait for explicit user confirmation before proceeding.

Financial operations require extra caution. Any action that affects money, billing, or access must include a summary of consequences (amounts, affected accounts, locations) and require confirmation.

Pagination

Square uses cursor-based pagination. List endpoints return a cursor field when more results exist:

GET /squareup/v2/payments?cursor={cursor_value}

Response includes pagination info:

{
  "payments": [...],
  "cursor": "next_page_cursor_value"
}

Continue fetching by passing the cursor value in subsequent requests until no cursor is returned.

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/squareup/v2/locations',
  {
    headers: {
      'Authorization': Bearer ${process.env.MATON_API_KEY}
    }
  }
);
const data = await response.json();

Python

import os
import requestsresponse = requests.get(
    'https://api.maton.ai/squareup/v2/locations',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Notes

All amounts are in the smallest currency unit (e.g., cents for USD: 1000 = $10.00)

IDs are alphanumeric strings

Timestamps are in ISO 8601 format (e.g., 2026-02-07T01:59:28.459Z)

Most write operations require an idempotency_key to prevent duplicate operations

Some endpoints require specific OAuth scopes (CUSTOMERS_READ, ORDERS_READ, ITEMS_READ, INVOICES_READ, etc.)

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 Square connection or bad request | | 401 | Invalid or missing Maton API key | | 403 | Insufficient OAuth scopes | | 404 | Resource not found | | 429 | Rate limited | | 4xx/5xx | Passthrough error from Square API |

Error Response Format

{
  "errors": [
    {
      "category": "INVALID_REQUEST_ERROR",
      "code": "NOT_FOUND",
      "detail": "Could not find payment with id: {payment_id}"
    }
  ]
}

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: Invalid App Name

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

Correct: https://api.maton.ai/squareup/v2/locations

Incorrect: https://api.maton.ai/v2/locations

Troubleshooting: Insufficient Scopes

If you receive a 403 error with INSUFFICIENT_SCOPES, the OAuth connection doesn't have the required permissions. Create a new connection and ensure you grant all necessary permissions during OAuth authorization.

Resources

💡 Examples

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