Google Sheets

Access the Google Sheets API with managed OAuth authentication. Read and write spreadsheet values, create sheets, apply formatting, and perform batch operations.

Quick Start

# Read values from a spreadsheet (note: range is URL-encoded)
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-sheets/v4/spreadsheets/SPREADSHEET_ID/values/Sheet1%21A1%3AD10')
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/google-sheets/{native-api-path}

Replace {native-api-path} with the actual Google Sheets API endpoint path. The gateway proxies requests to sheets.googleapis.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 Google 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=google-sheets&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': 'google-sheets'}).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": "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": "google-sheets",
    "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 Google accounts connected, 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/google-sheets/v4/spreadsheets/SPREADSHEET_ID')
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.

Code Examples

JavaScript

// Read values
const response = await fetch(
  'https://gateway.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:D10',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);

// Write values
await fetch(
  'https://gateway.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:B2?valueInputOption=USER_ENTERED',
  {
    method: 'PUT',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    },
    body: JSON.stringify({
      values: [['A1', 'B1'], ['A2', 'B2']]
    })
  }
);

Python

import os
import requests

# Read values
response = requests.get(
    'https://gateway.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:D10',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)

# Write values
response = requests.put(
    'https://gateway.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:B2',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'valueInputOption': 'USER_ENTERED'},
    json={'values': [['A1', 'B1'], ['A2', 'B2']]}
)

Notes

• When using curl, ranges in URL paths must be URL-encoded (! -> %21, : -> %3A). JavaScript fetch and Python requests handle encoding automatically.
• Use valueInputOption=USER_ENTERED to parse formulas and numbers
• Delete spreadsheets via the Google Drive API, not Sheets API
• Sheet IDs are numeric and found in the spreadsheet metadata
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) 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. You may get "Invalid API key" errors when piping.

Error Handling

Status	Meaning
400	Missing Google Sheets connection
401	Invalid or missing Maton API key
429	Rate limited (10 req/sec per account)
4xx/5xx	Passthrough error from Google Sheets API

Troubleshooting: Invalid API Key

When you receive a "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:

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://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
