How to add upload files features in a teams agent in Python

Hi @Amya Singhal 

Thank you for posting your question in the Microsoft Q&A forum. 

To add an upload feature in Teams agent using Python, you can follow these steps: 

1.Enable file support in the manifest 
To send and receive files in the bot, set the supportsFiles property in the manifest to true.
For example:    

 "bots": [ 
        { 
            "botId": "your-bot-Id", 
            "scopes": [ 
                "personal" 
            ], 
            "supportsFiles": true 
        } 
    ] 

This allows your bot to receive file attachments in chats. 
Please note that file upload is supported only in personal scope for Teams bots. It is not available in channels or group chats.

2.When a user uploads a file, Teams sends an attachment object in the activity payload. 
You can download the file using its contentUrl and a valid bot access token. 
Here's an example implementation in Python:

from botbuilder.core import ActivityHandler, TurnContext
from botframework.connector.auth import MicrosoftAppCredentials
import requests
import os

# Use environment variables for security
APP_ID = os.getenv("MicrosoftAppId")
APP_PASSWORD = os.getenv("MicrosoftAppPassword")

class FileUploadBot(ActivityHandler):
    async def on_message_activity(self, turn_context: TurnContext):
        if turn_context.activity.attachments:
            # Get OAuth token using MicrosoftAppCredentials
            creds = MicrosoftAppCredentials(APP_ID, APP_PASSWORD)
            access_token = await creds.get_access_token()

            for attachment in turn_context.activity.attachments:
                file_name = attachment.name
                content_url = attachment.content_url

                # Download file from Teams using contentUrl
                headers = {"Authorization": f"Bearer {access_token}"}
                response = requests.get(content_url, headers=headers)

                if response.status_code == 200:
                    with open(file_name, "wb") as f:
                        f.write(response.content)
                else:
                    await turn_context.send_activity(
                        f"Failed to download '{file_name}'. Status code: {response.status_code}"
                    )

            await turn_context.send_activity("File(s) received and saved successfully.")
        else:
            await turn_context.send_activity("Please upload a file.")
