Telegram

You first have to create a Telegram bot to get credentials. Once you have them you can add these to your credentials.yml.

Getting Credentials

How to get the Telegram credentials: You need to set up a Telegram bot.

1. To create the bot, go to Bot Father, enter /newbot and follow the instructions.
2. At the end you should get your access_token and the username you set will be your verify.
3. If you want to use your bot in a group setting, it’s advisable to turn on group privacy mode by entering /setprivacy. Then the bot will only listen when a user’s message starts with /bot.

For more information, check out the Telegram HTTP API.
