Unofficial Python SDK for Google Drive API, Google Sheets API, Google Calendar API, Google Docs API, and Google Slides API (Google Workspace)

GitHub • PyPI • Documentation • Issues

GoogleKit

GoogleKit is an unofficial Python SDK for the Google Drive API, Google Sheets API, Google Calendar API, Google Docs API, and Google Slides API.

GoogleKit is not affiliated with, endorsed by, or sponsored by Google LLC.

Use GoogleKit to upload and download Google Drive files, read and write Google Sheets spreadsheets, manage Google Calendar events, create Google Docs documents, and build Google Slides presentations — from one Python package. It wraps google-api-python-client with OAuth 2.0, service account, and Application Default Credentials (ADC) auth, least-privilege scopes, retries, and a clean typed API for Google Workspace automation, bots, scripts, and backend services.

Whether you need a Python Google Drive client, a Google Sheets Python library, a Google Calendar SDK, a Google Docs API wrapper, or a Google Slides API client, GoogleKit gives you one consistent Google Workspace Python SDK instead of wiring each Google API by hand.

Installation

pip install googlekit

Or with UV (recommended):

uv add googlekit

Google API client libraries are included by default — no extras required.

---

Quick Start

Unified client

from googlekit import GoogleKit

# Auto-authenticate with ADC or local credential JSON
client = GoogleKit.auto(services=["gdrive", "gsheets"])

page = client.drive.files.list(folder_id="root")
for f in page.items:
    print(f.name)

client.sheets.values.write(
    "spreadsheet_id",
    "Sheet1!A1",
    [["Name", "Score"], ["Ada", 98]],
)

Drive-only client

from googlekit.gdrive import DriveClient

drive = DriveClient.from_oauth("client_secrets.json")
drive.files.upload_path("report.pdf")

---

Authentication Methods

GoogleKit supports multiple authentication methods, ordered by recommendation for most workflows:

Method	Factory	Best For	Setup Required
1. Application Default Credentials	from_adc() / auto()	Local dev, Google Cloud	gcloud CLI
2. Service Account	from_service_account()	Servers, automation, bots	JSON key file
3. OAuth2 Client	from_oauth()	Personal scripts, desktop apps	JSON + browser auth

Security: never commit client_secrets.json, service-account keys, or token files. OAuth tokens default to an OS user config directory when token_path is omitted.

---

Method 1: Application Default Credentials (Recommended)

The easiest method for local development. No JSON files to manage!

Step-by-Step Setup

Step 1: Create a Google Cloud Project

1. Go to Google Cloud Console
2. Project dropdown → New Project → create and select it

Step 2: Enable APIs

Enable the APIs you need in APIs & Services → Library:

API	Enable
Google Drive	Enable Drive API
Google Sheets	Enable Sheets API
Google Calendar	Enable Calendar API
Google Docs	Enable Docs API
Google Slides	Enable Slides API

Step 3: Install Google Cloud SDK and sign in

1. Install Google Cloud SDK
2. Login with your Google account:

gcloud auth application-default login

Step 4: Use GoogleKit

from googlekit import GoogleKit

client = GoogleKit.from_adc(services=["gdrive"])
# or
client = GoogleKit.auto(services=["gdrive"])

How it Works

ADC checks these locations in order:

1. GOOGLE_APPLICATION_CREDENTIALS environment variable
2. gcloud auth application-default login credentials
3. Google Cloud metadata service (on GCE, Cloud Run, etc.)

---

Method 2: Service Account (For Automation)

Best for servers, bots, and CI/CD. No browser interaction.

Step-by-Step Setup

Step 1: Create a Google Cloud Project

1. Go to Google Cloud Console
2. Project dropdown → New Project → create and select it

Step 2: Enable APIs

Enable the APIs you need in APIs & Services → Library:

API	Enable
Google Drive	Enable Drive API
Google Sheets	Enable Sheets API
Google Calendar	Enable Calendar API
Google Docs	Enable Docs API
Google Slides	Enable Slides API

Step 3: Create Service Account + JSON Key

1. IAM & Admin → Service Accounts → Create
2. Keys → Add Key → Create new key → JSON
3. Rename the download to service_account.json and keep it out of git

Organization Policy Error

If key creation is blocked (iam.disableServiceAccountKeyCreation):

1. Use OAuth2 (Method 3) or ADC (Method 1)
2. Or ask your admin for an exception

Usage

from googlekit import GoogleKit

# Explicit
client = GoogleKit.from_service_account(
    "service_account.json",
    services=["gdrive", "gsheets"],
)

# Auto-detect (if service_account.json is in the working directory)
client = GoogleKit.auto(services=["gdrive"])

Aspect	OAuth2	Service Account
Browser needed	Yes (first time)	No
Whose data?	Your Google account	The service account identity
Best for	Personal scripts	Servers, automation
Access	Files you own / can open	Only resources shared with the SA email

Important: Service accounts start with an empty Drive. Share folders/files with the SA email (e.g. [e-mail]), or use domain-wide delegation with a subject.

---

Method 3: OAuth2 Client Credentials (Recommended for Personal Use)

For desktop apps that access your Google account. Opens a browser once.

Step-by-Step Setup

Step 1: Create a Google Cloud Project

1. Go to Google Cloud Console
2. Project dropdown → New Project → create and select it

Step 2: Enable APIs

Enable the APIs you need in APIs & Services → Library:

API	Enable
Google Drive	Enable Drive API
Google Sheets	Enable Sheets API
Google Calendar	Enable Calendar API
Google Docs	Enable Docs API
Google Slides	Enable Slides API

Step 3: Configure Google Auth Platform (OAuth app)

Google now uses Google Auth Platform (not only the old “OAuth consent screen” page). Complete these before creating a client:

1. Branding — app name, support email, developer contact
2. Audience — External (or Internal for Workspace); while testing, add yourself as a test user
3. Data Access — add the Google Workspace scopes you need (or GoogleKit will request them at runtime; listing them here helps consent / verification)

If the console still shows the older UI: APIs & Services → OAuth consent screen does the same job.

Step 4: Create OAuth client (Desktop)

You’re on the right page when you see Clients and + Create client (empty until you create one):

1. Open Google Auth Platform → Clients
2. + Create client
3. Application type: Desktop app
4. Name it (e.g. GoogleKit desktop) → Create
5. Download the JSON → rename to client_secrets.json (keep it out of git)

Older path (still works on some projects): APIs & Services → Credentials → Create Credentials → OAuth client ID → Desktop app.

Usage

from googlekit import GoogleKit

client = GoogleKit.from_oauth(
    "client_secrets.json",
    token_path="token.json",  # optional; defaults to OS config dir
    services=["gdrive", "gsheets", "gcalendar"],
)

First run: a browser window opens for consent. Tokens are cached for later runs.

Per-service clients:

from googlekit.gdrive import DriveClient

drive = DriveClient.from_oauth("client_secrets.json")

---

Environment Variable

# Linux/macOS
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/credentials.json"

# Windows PowerShell
$env:GOOGLE_APPLICATION_CREDENTIALS="C:\path\to\credentials.json"

client = GoogleKit.from_adc(services=["gdrive"])
# or
client = GoogleKit.auto(services=["gdrive"])

---

Auto-Detection Priority

When you call GoogleKit.auto(), credential discovery tries:

1. Application Default Credentials (gcloud login or GOOGLE_APPLICATION_CREDENTIALS)
2. Service account files in the working directory:
   • service_account.json
   • service_account_key.json
   • sa_credentials.json
3. OAuth client files in the working directory:
   • client_secrets.json
   • client_secret.json
   • credentials.json
   • oauth_credentials.json

---

API Overview

GoogleKit

GoogleKit.from_oauth(client_secrets, token_path=None, *, services=[...], profile=...)
GoogleKit.from_service_account(credentials_file, subject=None, *, services=[...], profile=...)
GoogleKit.from_adc(*, services=[...], profile=..., quota_project_id=None)
GoogleKit.auto(*, services=[...], profile=...)

services (or explicit scopes=) is required on unified constructors so GoogleKit never requests every Workspace write scope by default.

Lazy accessors: client.drive, client.sheets, client.calendar, client.docs, client.slides.

Drive (client.drive)

Manager	Highlights
files	list, iterate, search, get, upload_path, download_path, export, copy, move, rename, trash, restore, delete, empty_trash
folders	create, create_path, list_children, upload_directory, download_directory
permissions	share_user, share_group, share_domain, share_anyone (needs public=True), create_shareable_link, list, remove
changes	get_start_page_token, list, iterate

Sheets (client.sheets)

Manager	Highlights
values	read, read_multiple, write, write_multiple, append, clear
spreadsheets / worksheets	create, get, add/delete/duplicate sheets
formatting	text, number formats, borders, merge

Calendar (client.calendar)

Manager	Highlights
events	list, create, update, patch, delete (Meet via conference=True)
calendars	calendar list / CRUD
freebusy	availability queries

Docs / Slides

Client	Highlights
client.docs	documents.create / get, content helpers, tables, export / share via Drive
client.slides	presentations.create / get, pages, elements, tables, images, text replace

---

Usage Examples

Drive — list, upload, download

from googlekit import GoogleKit

client = GoogleKit.auto(services=["gdrive"])
drive = client.drive

page = drive.files.list(folder_id="root")
for f in page.items:
    print(f"{f.name} ({f.id})")

uploaded = drive.files.upload_path("document.pdf", parents=["folder_id"])
drive.files.download_path(uploaded.id, "local-copy.pdf")

Drive — folders and sharing

folder = drive.folders.create_path("Projects/2026")
drive.folders.upload_directory("./my_project", parent_id=folder.id)

drive.permissions.share_user(folder.id, "[e-mail]", role="writer")
link = drive.permissions.create_shareable_link(folder.id, public=True)
print(link)

Sheets

client = GoogleKit.auto(services=["gsheets"])

client.sheets.values.write(
    "spreadsheet_id",
    "Sheet1!A1:B2",
    [["Name", "Score"], ["Ada", 98]],
)
rows = client.sheets.values.read("spreadsheet_id", "Sheet1!A1:B10")
print(rows)

Calendar

from datetime import UTC, datetime, timedelta

client = GoogleKit.auto(services=["gcalendar"])
start = datetime.now(UTC)
end = start + timedelta(hours=1)

event = client.calendar.events.create(
    "primary",
    summary="Standup",
    start=start,
    end=end,
    conference=True,
)
print(event.id)

Docs & Slides

client = GoogleKit.auto(services=["gdocs", "gslides", "gdrive"])

doc = client.docs.documents.create("Proposal")
client.docs.content.insert_text(doc.id, "Hello from GoogleKit\n", index=1)

deck = client.slides.presentations.create("Pitch Deck")
print(deck.id)

---

OAuth Scopes

GoogleKit uses least-privilege scope presets per service:

Profile	Typical meaning
metadata	Minimal metadata access
readonly	Read-only
readwrite	Default for most apps
full	Broadest service scope

from googlekit import GoogleKit
from googlekit.auth.scopes import ScopeProfile

client = GoogleKit.from_oauth(
    "client_secrets.json",
    services=["gdrive"],
    profile=ScopeProfile.READONLY,
)

Missing scopes raise InsufficientScopesError with a clear reauth hint. Calendar readwrite includes events, calendars, calendarList, and freebusy so the full CalendarClient surface works under the default preset.

---

Error Handling

GoogleKit raises typed exceptions (it does not return {"success": false} dicts):

from googlekit import GoogleKit
from googlekit.core.exceptions import GoogleKitError, NotFoundError, ValidationError

client = GoogleKit.auto(services=["gdrive"])

try:
    client.drive.files.get("missing-id")
except NotFoundError as exc:
    print(exc)
except ValidationError as exc:
    print(exc)
except GoogleKitError as exc:
    print(exc)

Common types: AuthenticationError, InsufficientScopesError, NotFoundError, RateLimitError, QuotaExceededError, ValidationError, APIError.

---

CLI

uv run googlekit --version
uv run googlekit doctor
uv run googlekit auth status

doctor checks Python, Google client libraries, detected credential files, and token cache paths — without printing secrets.
