Square

Square API integration with managed OAuth. Process payments, manage customers, orders, catalog, inventory, and invoices. Use this skill when users want to accept payments, manage point-of-sale operations, track inventory, or handle invoicing through Square. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key.

Installer
$clawhub install squareup

Square

Access the Square API with managed OAuth authentication. Process payments, manage customers, orders, catalog items, inventory, and invoices.

Quick Start

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

Replace {native-api-path} with the actual Square API endpoint path. The gateway proxies requests to connect.squareup.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 Square 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=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://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: json { "connection": { "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80", "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://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 Square 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/squareup/v2/locations')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

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

Python

import os
import requests

response = requests.get(
    'https://gateway.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
  1. 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: Invalid App Name

  1. Ensure your URL path starts with squareup. For example:
  • Correct: https://gateway.maton.ai/squareup/v2/locations
  • Incorrect: https://gateway.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.
