Using Python's MSGraph SDK to Send Emails

Using Python SDK with MSGraph for Email Automation

Python Code for Email Functions in MSGraph

from msgraph.core import GraphClient
from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session
client_id = 'YOUR_CLIENT_ID'
client_secret = 'YOUR_CLIENT_SECRET'
tenant_id = 'YOUR_TENANT_ID'
token_url = f'https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/token'
client = BackendApplicationClient(client_id=client_id)
oauth = OAuth2Session(client=client)
token = oauth.fetch_token(token_url=token_url, client_id=client_id, client_secret=client_secret)
client = GraphClient(credential=token)
message = {
    "subject": "Meet for lunch?",
    "body": {
        "contentType": "Text",
        "content": "The new cafeteria is open."
    },
    "toRecipients": [{
        "emailAddress": {"address": "frannis@contoso.com"}
    }],
    "ccRecipients": [{
        "emailAddress": {"address": "danas@contoso.com"}
    }]
}
save_to_sent_items = False
response = client.api('/me/sendMail').post({"message": message, "saveToSentItems": str(save_to_sent_items).lower()})
print(response.status_code)

Handling Absent Classes in the MSGraph SDK

Python Error Handling for MSGraph API

class SendMailPostRequestBody:
    def __init__(self, message, save_to_sent_items):
        self.message = message
        self.save_to_sent_items = save_to_sent_items
try:
    from msgraph.generated.models import Message, Recipient, EmailAddress
except ImportError as e:
    print(f"Failed to import MSGraph models: {str(e)}")
    # Define missing classes manually if not available
    class Message:
        def __init__(self, subject, body, to_recipients, cc_recipients):
            self.subject = subject
            self.body = body
            self.to_recipients = to_recipients
            self.cc_recipients = cc_recipients
    class Recipient:
        def __init__(self, email_address):
            self.email_address = email_address
    class EmailAddress:
        def __init__(self, address):
            self.address = address

Frequently Asked Questions Concerning Python with MSGraph

1. In Python, how can I authenticate to the Microsoft Graph API?
2. OAuth 2.0 protocols can be used for authentication. Getting access tokens from a Microsoft identity platform endpoint is the standard procedure.
3. Can I use MSGraph in Python to transmit attachments?
4. Yes, you may use the sendMail method to send attachments after creating the necessary JSON payload with the attachment data.
5. Is it feasible to use MSGraph to send emails with HTML formatting?
6. The Graph API can indeed allow HTML emails. The email body's contentType must be set to HTML.
7. How can I use MSGraph to add BCC and CC recipients to an email?
8. You can add recipients to the CC and BCC lists by adding their email addresses in the message object's ccRecipients and bccRecipients attributes.
9. Is MSGraph able to read and handle incoming emails?
10. Yes, MSGraph has the ability to read emails from a user's mailbox so that they can be handled or kept for later.

Finalizing Email Automation with MSGraph

By investigating the Microsoft Graph API and its Python SDK, developers can acquire strong instruments for automating email functions in their applications. Emails with attachments and rich content formats can be managed programmatically, enabling more effective and dynamic company communication methods. Developers working in Microsoft-centric workplaces will find MSGraph to be a great resource as the examples and recommendations offered ensure a smooth implementation.
