Creating subscription with "prefer:includesecuritywebhooks"

[yusufugurozbek]

Hello,

I'd like to get notified when there is a sharing change on drive items (Business SharePoint/OneDrive). To do that, I created a subscription with the prefer:includesecuritywebhooks option as mentioned here. The below code doesn't help me. Could you please guide me on that?

async def create_subscription():
    expiration_date_time: datetime = datetime.now(tz=tz.UTC) + timedelta(minutes=42300)

    request_body = Subscription(
        change_type="updated",
        notification_url="{WEBHOOK_URL}",
        resource="/drives/{DRIVE_ID}}/root",
        expiration_date_time=expiration_date_time,
        client_state="secretClientValue",
    )

    headers_collection = HeadersCollection()
    headers_collection.add("prefer", "includesecuritywebhooks")
    request_configuration = RequestConfiguration(headers=headers_collection)

    return await client.subscriptions.post(
        request_body, request_configuration=request_configuration
    )

Thanks,
Yusuf Ugur
