Google Sheets

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
curl -s -X GET 'https://gateway.maton.ai/google-sheets/v4/spreadsheets/SPREADSHEET_ID/values/Sheet1!A1:D10' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Base URL

https://gateway.maton.ai/google-sheets/v4/spreadsheets/{spreadsheetId}/{endpoint}

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 YOUR_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 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

curl -s -X GET 'https://ctrl.maton.ai/connections?app=google-sheets&status=ACTIVE' \

Get Connection

curl -s -X GET 'https://ctrl.maton.ai/connections/{connection_id}' \

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

• Range in URL path must be URL-encoded (! → %21, : → %3A)
• 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
