Telegram Bundle

Known issues

No known issues.

Configuration

  • telegram.secret -- arbitrary key that is not known to the public. This key is used in the telegram.url parameter when setting webhook. The idea is the resulting URL is known only to you and Telegram server so you can trust updates you receive at your endpoint. Good idea is to make it quite long ([0-9a-z]{32} for example).
  • telegram.token -- Telegram bot API key you got from the BotFather.
  • telegram.certificate_file -- open part of the certificate to send to Telegram server when registering webhook. This might be a self-signed certificate, see Telegram documentation.
  • telegram.url -- a URL of this bot with a {secret} substring in it. For example: https://www.your-domain.com/api/v1/{secret}/webhook
  • telegram.self_user_id -- Telegram „user ID“ of the bot. It is required to distinguish the bot itself on chat join/left events.
