Decorators for automatically notifying an MS Teams channel of events

msteamsnotifiers: Decorators for automatically notifying an MS Teams channel of events

msteamsnotifiers makes it easy to automatically send notifications to a channel in MS Teams from Python.

With the upcoming retirement of Office 365 Connectors, this library has been updated to use Workflows. Follow the instructions in this simple, short video to set up the Workflow for your Teams channel. You can then get the webhook URL from the "When a Teams webhook request is received" step of the workflow (it's the auto-generated HTTP POST URL field, which has a handy 'copy' button next to it).

Installation

Install with pip:

pip install msteamsnotifiers

Usage

All the functions provided in msteamsnotifiers can take the webhook URL as an argument. If not specified, the value in msteamsnotifiers.default_webhook_url will be used. This allows you to set this once and then not have to pass it to the other functions each time they are used:

import msteamsnotifiers

msteamsnotifiers.default_webhook_url = '<your Microsoft webhook URL>'

Posting simple messages to a channel

This is the simplest way of posting very simple messages to a channel in MS Teams.

import msteamsnotifiers

msteamsnotifiers.default_webhook_url = '<your Microsoft webhook URL>'

msteamsnotifiers.post_simple_teams_message('Hello channel!')
msteamsnotifiers.post_simple_teams_message('[Markdown formatting](https://www.markdownguide.org/) is supported.')
msteamsnotifiers.post_simple_teams_message('This was sent using [msteamsnotifiers](https://pypi.org/project/msteamsnotifiers/)')

Notifying a channel of an exception

@notify_exceptions is a decorator that will catch any exceptions in the decorated function and send a specially formatted message with details about the exception to a channel.

import msteamsnotifiers
from msteamsnotifiers import notify_exceptions

msteamsnotifiers.default_webhook_url = '<your Microsoft webhook URL>'

@notify_exceptions()
def fn_with_potential_exception(a, b):
    return a + b

# This function call completes successfully, so the channel will not be notified
sum1 = fn_with_potential_exception(1, 2)

# This function call will generate an exception, resulting in the channel being notified
sum2 = fn_with_potential_exception('a', True)

The format of the channel notification can be specified using the template decorator argument. If no template is specified, the default template is msteamsnotifiers.default_exception_template, which includes the full traceback:

default_exception_template = """
*{timestamp}*  
Exception caught in **{funcname}()**, File **"{filename}"**  
**{message}**  
<br>
Node: {machine_name} ({ip_address})
<br>

```{where}```

args: {args}  
kwargs: {kwargs}

Full traceback:  
```{traceback}```
"""

This package variable can be modified similarly to the default_webhook_url parameter.

The friendly_tracebacks module is used to format the included traceback to make it easier to read.

Notifying a channel of a function's completion

@notify_complete is a decorator that will send a message to a channel upon successful completion of the decorated function.

import msteamsnotifiers
from msteamsnotifiers import notify_complete

msteamsnotifiers.default_webhook_url = '<your Microsoft webhook URL>'

import time

@notify_complete()
def long_running_function(a, b):
    print('Thinking... thinking... thinking...')
    time.sleep(3600)
    print(f"Aha! The answer is {a+b}!")
    return a + b

# The channel will be notified upon completion of this function call
sum1 = long_running_function(1, 2)

The format of this message can be specified using the template decorator argument. If no template is specified, the default template is msteamsnotifiers.default_completion_template:

default_completion_template = """
*{timestamp}*  
Function completed: **{funcname}()** in file **"{filename}"**  
Node: {machine_name} ({ip_address})  
args: {args}  
kwargs: {kwargs}
"""
