Working with SharePoint API

The list of supported API versions:

Authentication

The following auth flows are supported:

Examples

There are two approaches available to perform API queries:

  1. ClientContext class - where you target SharePoint resources such as Web, ListItem and etc (recommended)
from office365.runtime.auth.user_credential import UserCredential
from office365.sharepoint.client_context import ClientContext
site_url = "https://{your-tenant-prefix}.sharepoint.com"
ctx = ClientContext(site_url).with_credentials(UserCredential("{username}", "{password}"))
web = ctx.web
ctx.load(web)
ctx.execute_query()
print("Web title: {0}".format(web.properties['Title']))

or alternatively via method chaining (a.k.a Fluent Interface):

from office365.runtime.auth.user_credential import UserCredential
from office365.sharepoint.client_context import ClientContext
site_url = "https://{your-tenant-prefix}.sharepoint.com"
ctx = ClientContext(site_url).with_credentials(UserCredential("{username}", "{password}"))
web = ctx.web.get().execute_query()
print("Web title: {0}".format(web.properties['Title']))
  1. RequestOptions class - where you construct REST queries (and no model is involved)

    The example demonstrates how to read Web properties:

import json
from office365.runtime.auth.user_credential import UserCredential
from office365.runtime.http.request_options import RequestOptions
from office365.sharepoint.client_context import ClientContext
site_url = "https://{your-tenant-prefix}.sharepoint.com"
ctx = ClientContext(site_url).with_credentials(UserCredential("{username}", "{password}"))
request = RequestOptions("{0}/_api/web/".format(site_url))
response = ctx.execute_request_direct(request)
json = json.loads(response.content)
web_title = json['d']['Title']
print("Web title: {0}".format(web_title))

The list of examples:

Working with Outlook API

The list of supported APIs:

Since Outlook REST APIs are available in both Microsoft Graph and the Outlook API endpoint, the following clients are available:

  • GraphClient which targets Outlook API v2.0 version (preferable nowadays, refer transition to Microsoft Graph-based Outlook REST API for a details)
    - OutlookClient which targets Outlook API v1.0 version (not recommended for usage since v1.0 version is being deprecated.)

Authentication

The Microsoft Authentication Library (MSAL) for Python which comes as a dependency is used as a default library to obtain tokens to call Microsoft Graph API.

Using Microsoft Authentication Library (MSAL) for Python

Note: access token is getting acquired via Client Credential flow in the provided examples

import msal
from office365.graph_client import GraphClient

def acquire_token():
    """
    Acquire token via MSAL
    """
    authority_url = 'https://login.microsoftonline.com/{tenant_id_or_name}'
    app = msal.ConfidentialClientApplication(
        authority=authority_url,
        client_id='{client_id}',
        client_credential='{client_secret}'
    )
    token = app.acquire_token_for_client(scopes=["https://graph.microsoft.com/.default"])
    return token


client = GraphClient(acquire_token)

But in terms of Microsoft Graph API authentication, another Microsoft Authentication Client compliant libraries such as adal are supported as well.

Using ADAL Python

Usage

import adal
from office365.graph_client import GraphClient

def acquire_token():
    authority_url = 'https://login.microsoftonline.com/{tenant_id_or_name}'
    auth_ctx = adal.AuthenticationContext(authority_url)
    token = auth_ctx.acquire_token_with_client_credentials(
        "https://graph.microsoft.com",
        "{client_id}",
        "{client_secret}")
    return token

client = GraphClient(acquire_token)

Example

The example demonstrates how to send an email via Microsoft Graph endpoint.

Note: access token is getting acquired via Client Credential flow

from office365.graph_client import GraphClient

client = GraphClient(acquire_token)

message_json = {
    "Message": {
        "Subject": "Meet for lunch?",
        "Body": {
            "ContentType": "Text",
            "Content": "The new cafeteria is open."
        },
        "ToRecipients": [
            {
                "EmailAddress": {
                    "Address": "[email protected]"
                }
            }
        ]
    },
    "SaveToSentItems": "false"
}

login_name = "[email protected]"
client.users[login_name].send_mail(message_json)
client.execute_query()

Working with OneDrive API

Documentation

OneDrive Graph API reference

Authentication

The Microsoft Authentication Library (MSAL) for Python which comes as a dependency is used to obtain token

import msal

def acquire_token():
    """
    Acquire token via MSAL
    """
    authority_url = 'https://login.microsoftonline.com/{tenant_id_or_name}'
    app = msal.ConfidentialClientApplication(
        authority=authority_url,
        client_id='{client_id}',
        client_credential='{client_secret}'
    )
    token = app.acquire_token_for_client(scopes=["https://graph.microsoft.com/.default"])
    return token

Examples

Example: list available drives

The example demonstrates how to enumerate and print drive's url which corresponds to list available drives endpoint

Note: access token is getting acquired via Client Credential flow

from office365.graph_client import GraphClient

tenant_name = "contoso.onmicrosoft.com"
client = GraphClient(acquire_token)
drives = client.drives
client.load(drives)
client.execute_query()
for drive in drives:
    print("Drive url: {0}".format(drive.web_url))
Example: download the contents of a DriveItem(folder facet)
from office365.graph_client import GraphClient
client = GraphClient(acquire_token)
# retrieve drive properties 
drive = client.users["{user_id_or_principal_name}"].drive
client.load(drive)
client.execute_query()

# download files from OneDrive into local folder 
with tempfile.TemporaryDirectory() as path:
    download_files(drive.root, path)

where

def download_files(remote_folder, local_path):
    drive_items = remote_folder.children
    client.load(drive_items)
    client.execute_query()
    for drive_item in drive_items:
        if not drive_item.file.is_server_object_null:  # is file?
            # download file content
            with open(os.path.join(local_path, drive_item.name), 'wb') as local_file:
                drive_item.download(local_file)
                client.execute_query()

Refer OneDrive examples section for a more examples.

Working with Microsoft Teams API

Authentication

The Microsoft Authentication Library (MSAL) for Python which comes as a dependency is used to obtain token

Examples

Example: create a new team under a group

The example demonstrates how create a new team under a group which corresponds to Create team endpoint

from office365.graph_client import GraphClient
tenant_name = "contoso.onmicrosoft.com"
client = GraphClient(tenant_name, acquire_token)
new_team = client.groups["{group_id}"].add_team()
client.execute_query()
