SharePoint API Client

A modern Python library for interacting with Microsoft SharePoint sites using the Microsoft Graph API. Built with httpx for high-performance async/sync operations, automatic connection management, and streaming support for large files.

Features

✨ Modern httpx-based implementation with HTTP/2 support ready
🔄 Both sync and async clients with identical APIs
🚀 Automatic URL parsing - just paste SharePoint URLs
💾 Streaming support for large file uploads/downloads
🔧 Automatic connection management with configurable cleanup
📁 Rich data models with comprehensive SharePoint object support
🛡️ OAuth2 authentication via Microsoft Graph API

Installation

pip install sharepoint-api-py
# or
poetry add sharepoint-api-py

Quick Start

1. Setup Credentials

Create a .env file or set environment variables:

SHAREPOINT_TENANT_ID="your_tenant_id"
SHAREPOINT_APP_ID="your_app_id"  
SHAREPOINT_APP_SECRET="your_app_secret"

2. Basic Usage

from sharepoint_api import SharePointClient

# Initialize client from environment
client = SharePointClient.from_env()

# Upload a file - just provide local path and SharePoint folder URL
client.upload(
    "./report.pdf",
    "https://contoso.sharepoint.com/sites/MyTeam/Shared%20Documents/Reports/"
)

# Download a file - just provide SharePoint file URL and local folder
client.download(
    "https://contoso.sharepoint.com/sites/MyTeam/Shared%20Documents/data.xlsx",
    target_path="./downloads/"
)

3. Async Usage

from sharepoint_api import AsyncSharePointClient

async def main():
    client = AsyncSharePointClient.from_env()
    
    # Same simple API, but async
    await client.upload(
        "./large_dataset.csv",
        "https://contoso.sharepoint.com/sites/MyTeam/Documents/"
    )
    
    await client.download(
        "https://contoso.sharepoint.com/sites/MyTeam/Documents/results.xlsx",
        target_path="./downloads/"
    )

Core Concepts

Automatic URL Parsing

No need to manually extract site IDs, drive names, or folder paths. Just copy SharePoint URLs from your browser:

# Copy any SharePoint URL from your browser and use it directly
client.upload("./file.pdf", "https://contoso.sharepoint.com/sites/TeamSite/Documents/Reports/")
client.download("https://contoso.sharepoint.com/sites/TeamSite/Documents/file.xlsx", "./downloads/")

Context Management

The client automatically handles all the complexity behind the scenes. You just provide URLs:

# No setup needed - each operation is self-contained
client.upload("./file1.txt", "https://sharepoint.com/sites/TeamA/Documents/")
client.upload("./file2.txt", "https://sharepoint.com/sites/TeamB/Reports/")  # Different site? No problem!

Streaming for Large Files

Large files are automatically streamed to avoid memory issues:

# Files larger than threshold (default: 100MB) are automatically streamed
large_file = client.download("https://sharepoint.com/huge_dataset.csv")

# Force streaming for any file
client.download_file(file_obj, use_streaming=True)

# Configure thresholds
client = SharePointClient.from_env(
    large_file_threshold=50*1024*1024,  # 50MB threshold
    auto_close_timeout=60  # Close idle connections after 60s
)

API Reference

Client Initialization

from sharepoint_api import SharePointClient, AsyncSharePointClient
from sharepoint_api.config import SharepointConfig

# From environment variables
client = SharePointClient.from_env()

# From config object
config = SharepointConfig(
    tenant_id="...",
    client_id="...", 
    client_secret="...",
    resource_url="https://graph.microsoft.com/",
    resource_url_version="v1.0"
)
client = SharePointClient.from_config(config)

# With custom settings
client = SharePointClient.from_env(
    auto_close_timeout=120,  # Close idle connections after 2 minutes
    large_file_threshold=200*1024*1024  # 200MB streaming threshold
)

File and Folder Operations

# Upload files - just provide local path and SharePoint folder URL
client.upload("./document.pdf", "https://sharepoint.com/sites/Team/Documents/Reports/")

# Download files - provide SharePoint file URL and local destination
client.download("https://sharepoint.com/sites/Team/Documents/report.xlsx", "./downloads/")

# Browse folder contents (if needed)
folder = client.path("https://sharepoint.com/sites/Team/Documents/Reports/")
for item in folder.children:
    print(f"📄 {item.name}")

Data Models

Rich data models provide comprehensive SharePoint object information:

from sharepoint_api import GraphSiteData, DriveFolder, DriveFile, FileSize

# Site information
site = client.get_site(site_name="TeamSite")
print(f"Site: {site.name} ({site.web_url})")

# File information with rich metadata
file = client.path("https://sharepoint.com/file.xlsx")
print(f"File: {file.name}")
print(f"Size: {file.size}")  # Automatically formatted (e.g., "1.5 MB") 
print(f"Modified: {file.last_modified_date_time}")
print(f"Download URL: {file.download_url}")

# Folder with children
folder = client.path("https://sharepoint.com/folder/")
for item in folder.children:
    item_type = "📁" if isinstance(item, DriveFolder) else "📄"
    print(f"{item_type} {item.name}")

Advanced Usage

Custom Authentication

# Use your own OAuth2 tokens
client = SharePointClient(
    client_id="your_app_id",
    client_secret="your_secret", 
    tenant_id="your_tenant",
    resource_url="https://graph.microsoft.com/",
    resource_url_version="v1.0"
)

Error Handling

from sharepoint_api.core.errors import SharepointAPIError

try:
    file = client.download("https://sharepoint.com/nonexistent.xlsx")
except SharepointAPIError as e:
    print(f"SharePoint API error: {e}")
except Exception as e:
    print(f"General error: {e}")

Performance Tuning

# Configure connection pooling and timeouts
client = SharePointClient.from_env(
    auto_close_timeout=300,  # 5 minute idle timeout
    large_file_threshold=500*1024*1024,  # 500MB streaming threshold
)

# HTTP/2 support (requires h2 package)
# pip install h2
# client.http2 = True  # Coming soon
