README
# webexteamsbot
This package makes creating [Webex Teams](https://www.webex.com/products/teams/index.html) bots in Python super simple.
[](https://badge.fury.io/py/webexteamsbot) [](https://developer.cisco.com/codeexchange/github/repo/hpreston/webexteamsbot)
> This package is based on the previous [ciscosparkbot](https://github.com/imapex/ciscosparkbot) project. This version will both move to new Webex Teams branding as well as add new functionality. If you've used `ciscosparkbot` you will find this package very similar and familiar.
# Prerequisites
If you don't already have a [Webex Teams](https://www.webex.com/products/teams/index.html) account, go ahead and [register](https://www.webex.com/pricing/free-trial.html) for one. They are free.
1. You'll need to start by adding your bot to the Webex Teams website.
[https://developer.webex.com/my-apps](https://developer.webex.com/my-apps)
1. Click **Create a New App**
1. Click **Create a Bot**.
2. Fill out all the details about your bot. You'll need to set a name, username, icon (either upload one or choose a sample), and provide a description.
3. Click **Add Bot**.
1. On the Congratulations screen, make sure to copy the *Bot's Access Token*, you will need this in a second.
# Installation
> Python 3.6+ is recommended. Python 2.7 should also work.
1. Create a virtualenv and install the module
```
python3.6 -m venv venv
source venv/bin/activate
pip install webexteamsbot
```
# Usage
1. The easiest way to use this module is to set a few environment variables
> Note: See [ngrok](#ngrok) for details on setting up an easy HTTP tunnel for development.
```
export TEAMS_BOT_URL=https://mypublicsite.io
export TEAMS_BOT_TOKEN=
export TEAMS_BOT_EMAIL=
export TEAMS_BOT_APP_NAME=
```
1. A basic bot requires very little code to get going.
```python
import os
from webexteamsbot import TeamsBot
# Retrieve required details from environment variables
bot_email = os.getenv("TEAMS_BOT_EMAIL")
teams_token = os.getenv("TEAMS_BOT_TOKEN")
bot_url = os.getenv("TEAMS_BOT_URL")
bot_app_name = os.getenv("TEAMS_BOT_APP_NAME")
# Create a Bot Object
bot = TeamsBot(
bot_app_name,
teams_bot_token=teams_token,
teams_bot_url=bot_url,
teams_bot_email=bot_email,
)
# A simple command that returns a basic string that will be sent as a reply
def do_something(incoming_msg):
"""
Sample function to do some action.
:param incoming_msg: The incoming message object from Teams
:return: A text or markdown based reply
"""
return "i did what you said - {}".format(incoming_msg.text)
# Add new commands to the box.
bot.add_command("/dosomething", "help for do something", do_something)
if __name__ == "__main__":
# Run Bot
bot.run(host="0.0.0.0", port=5000)
```
1. A [sample script](https://github.com/hpreston/webexteamsbot/blob/master/sample.py) that shows more advanced bot features and customization is also provided in the repo.
## Advanced Options
### Changing the Help Message
1. Although "set_greeting" has existed for a while now, you may mostly like the internal greeting mechanism, but only want to change the help banner itself. You can do that with the "set_help_message" command like this:
```python
bot.set_help_message("Welcome to the Super Cool Bot! You can use the following commands:\n")
```
### Working with events other than created messages
1. By default, the bot will configure the webhook to listen for messages:created events. This behavior can be changed using the "webhook_resource" and "webhook_event" parameters. So, for example, if you wish for the bot to monitor any changes to a room's membership list, you would instanciate the bot like this:
```python
# Create a Bot Object
bot = TeamsBot(
bot_app_name,
teams_bot_token=teams_token,
teams_bot_url=bot_url,
teams_bot_email=bot_email,
webhook_resource="memberships",
webhook_event="all",
)
```
You also need a way to catch anything other than "messages", which is the only thing handled entirely inside the bot framework. Continuing the example of monitoring for membership changes in a room, you would also need to add a "command" to catch the membership events. You would use the following to do so:
```python
# check membership:all webhook to verify that person added to room (or otherwise modified) is allowed to be in the room
def check_memberships(api, incoming_msg):
wl_dom = os.getenv("WHITELIST_DOMAINS")
if wl_dom.find("[") < 0:
wl_dom = '["' + wl_dom + '"]'
wl_dom = wl_dom.replace(",", '","')
if wl_dom and incoming_msg["event"] != "deleted":
pemail = incoming_msg["data"]["personEmail"]
pid = incoming_msg["data"]["personId"]
pdom = pemail.split("@")[1]
plist = json.loads(wl_dom)
print(pemail, pdom, plist)
if pdom in plist or pemail == bot_email:
# membership check succeeded
return ""
else:
# membership check failed
print("membership failed. deleting " + incoming_msg["data"]["id"])
api.memberships.delete(incoming_msg["data"]["id"])
api.messages.create(toPersonId=pid, markdown="You were automatically removed from the space because "
"it is restricted to employees.")
return "'" + pemail + "' was automatically removed from this space; it is restricted to only " \
"internal users."
return ""
######
bot.add_command('memberships', '*', check_memberships)
```
The first argument, "memberships", tells the bot to look for resources of the type "memberships", the second argument "*" instructs the bot that this is not something that should be included in the internal "help" command, and the third command is the function to execute to handle the membership creation.
1. The bot can also be configured to listen for multiple different events. So, for example, if you wish for the bot to monitor not only new messages in a room, but also any card actions in a room, you would instanciate the bot like this:
```python
# Create a Bot Object
bot = TeamsBot(
bot_app_name,
teams_bot_token=teams_token,
teams_bot_url=bot_url,
teams_bot_email=bot_email,
webhook_resource_event=[{"resource": "messages", "event": "created"},
{"resource": "attachmentActions", "event": "created"}]
)
```
Once again, You also need a way to catch anything other than "messages". Continuing the example of monitoring card actions, you would also need to add a "command" to catch the card actions. You would use the following to do so:
```python
# API request to get card actions (not currently covered in webexteamssdk==1.2)
def get_attachment_actions(attachmentid):
headers = {
'content-type': 'application/json; charset=utf-8',
'authorization': 'Bearer ' + teams_token
}
url = 'https://api.ciscospark.com/v1/attachment/actions/' + attachmentid
response = requests.get(url, headers=headers)
return response.json()
# check attachmentActions:created webhook to handle any card actions
def handle_cards(api, incoming_msg):
m = get_attachment_actions(incoming_msg["data"]["id"])
print(m)
return m["inputs"]
######
bot.add_command('attachmentActions', '*', handle_cards)
```
The first argument, "attachmentActions", tells the bot to look for resources of the type "attachmentActions", the second argument "*" instructs the bot that this is not something that should be included in the internal "help" command, and the third command is the function to execute to handle the card action.
### Creating arbitrary HTTP Endpoints/URLs
1. You can also add a new path to Flask by using the "add_new_url" command. You can use this so that the bot can handle things other than Webex Teams Webhooks. For example, if you wanted to receive other webhooks to the "/webhooks" path, you would use this:
```python
def handle_webhooks():
try:
webhook_event = json.loads(request.data.decode("UTF-8"))
except:
return ""
netid = webhook_event["networkId"]
print(netid)
######
bot.add_new_url("/webhooks", "webhooks", handle_webhooks)
```
The first argument, "/webhooks", represents the URL path to listen for, the second argument represents the Flask endpoint, and the third command is the function to execute to handle GET, PUT, or POST actions.
### Limiting Who Can Interact with the Bot
1. By default the bot will reply to any Webex Teams user who talks with it. But you may want to setup a Bot that only talks to "approved users".
1. Start by creating a list of email addresses of your approved users.
```python
approved_users = [
"[email protected]",
]
```
1. Now when creating the bot object, simply add the `approved_users` parameter.
```python
bot = TeamsBot(
bot_app_name,
teams_bot_token=teams_token,
teams_bot_url=bot_url,
teams_bot_email=bot_email,
approved_users=approved_users,
)
```
1. Now if a users **NOT** listed in the `approved_users` list attempts to communicate with the bot, the message will be ignored and a notification is logged.
```
Message from: [email protected]
User: [email protected] is not approved to interact with bot. Ignoring.
```
# Deploy in Cisco Exchange Dev environment
If you run this project using Cisco Exchange Dev environment
Open a new terminal and run the command to get the external URL:
`echo $DEVENV_APP_9082_URL`
As output, you will see an external URL for the webhook
For example
`https://app-9082-8093942179345178980.devenv-int.ap-ne-1.devnetcloud.com`
Update your environment with this url
`export TEAMS_BOT_URL=https://this.is.the.url.you.need`
In VSCode DevEnv open file `sample.py`
At the bottom, in code `bot.run(host="0.0.0.0", port=5000)` change the port from `5000` to `9082`
How it should look like: `bot.run(host="0.0.0.0", port=9082)`
Launch your bot
```
python sample.py
```
