squareup（squareup 搜索）

Square

Access the Square API with managed OAuth authentication. Read and manage payments, customers, orders, catalog items, inventory, invoices, loyalty programs, team members, and locations.

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 payments, customers, orders, catalog items, inventory, invoices, loyalty programs, team members, and locations within the connected Square account. This is broad access to financial and business-operation data — only install if you need Square administration. Use least-privilege OAuth scopes where 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. Processing payments, creating invoices, modifying catalog pricing, adjusting inventory counts, and managing team member permissions can have real financial and operational impact. These actions 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 requests

response = 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

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://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.
