Channels are configured from your name menu → Settings and Telegram:

- Telegram: open the bot shown, write to it and paste the Chat ID.
- Email: the address where you receive alerts.
- Discord or Slack: create a webhook in the channel (Discord: Channel settings → Integrations → Webhooks; Slack: “Incoming Webhooks” app) and paste the address.
- Push: notifications even with the app closed. They must be enabled on each device (they need HTTPS and the browser's permission). On a phone it's best to install the app on the Home screen.
- Sounds: default sound and volume.
Each alert then chooses its own channels. An alert's Webhook sends an HTTP request to an address of your choice, for example for a trading bot.
If Telegram or email aren't configured on the server, the settings say so: the administrator has to enable them.
Notification texts (alerts, email, Telegram, push) are written in the language chosen in the settings; quick alert conditions keep the language they were created in.
