# To use this plugin, you need to first access https://api.telegram.org
|
|
# You need to create a bot and acquire it's Token Identifier (bot_token)
|
|
#
|
|
# Basically you need to create a chat with a user called the 'BotFather'
|
|
# and type: /newbot
|
|
#
|
|
# Then follow through the wizard, it will provide you an api key
|
|
# that looks like this:123456789:alphanumeri_characters
|
|
#
|
|
# For each chat_id a bot joins will have a chat_id associated with it.
|
|
# You will need this value as well to send the notification.
|
|
#
|
|
# Log into the webpage version of the site if you like by accessing:
|
|
# https://web.telegram.org
|
|
#
|
|
# You can't check out to see if your entry is working using:
|
|
# https://api.telegram.org/botAPI_KEY/getMe
|
|
#
|
|
# Pay attention to the word 'bot' that must be present infront of your
|
|
# api key that the BotFather gave you.
|
|
#
|
|
# For example, a url might look like this:
|
|
# https://api.telegram.org/bot123456789:alphanumeric_characters/getMe
