# To use this plugin, you need to create a webhook; you can read more about
# this here:
# https://dev.outlook.com/Connectors/\
# GetStarted#creating-messages-through-office-365-connectors-\
# in-microsoft-teams
#
# More details are here on API Construction:
# https://docs.microsoft.com/en-ca/outlook/actionable-messages/\
# message-card-reference
#
# I personally created a free account at teams.microsoft.com and then
# went to the store (bottom left hand side of slack like interface).
#
# From here you can search for 'Incoming Webhook'. Once you click on it,
# you can associate the webhook with your team. At this point, you can
# optionally also assign it a name, an avatar. Finally you'll have to
# assign it a channel it will notify.
#
# When you've completed this, it will generate you a (webhook) URL that
# looks like:
# https://team-name.webhook.office.com/webhookb2/ \
# abcdefgf8-2f4b-4eca-8f61-225c83db1967@abcdefg2-5a99-4849-8efc-\
# c9e78d28e57d/IncomingWebhook/291289f63a8abd3593e834af4d79f9fe/\
# a2329f43-0ffb-46ab-948b-c9abdad9d643
#
# Yes... The URL is that big... But it looks like this (greatly simplified):
# https://TEAM-NAME.webhook.office.com/webhookb2/ABCD/IncomingWebhook/DEFG/HIJK
# ^ ^ ^ ^
# | | | |
# These are important <--------------------------^--------------------^----^
#
# The Legacy format didn't have the team name identified and reads 'outlook'
# While this still works, consider that Microsoft will be dropping support
# for this soon, so you may need to update your IncomingWebhook. Here is
# what a legacy URL looked like:
# https://outlook.office.com/webhook/ABCD/IncomingWebhook/DEFG/HIJK
# ^ ^ ^ ^
# | | | |
# legacy team reference: 'outlook' | | |
# | | |
# These are important <--------------^--------------------^----^
#
# You'll notice that the first token is actually 2 separated by an @ symbol
# But lets just ignore that and assume it's one great big token instead.
#
# These 3 tokens need to be placed in the URL after the Team
# msteams://TEAM/ABCD/DEFG/HIJK
