# Extract the next new post in a public channel — Telegram Public Channels

Botize method — `public_channels.new_post` (trigger).

It is triggered every time there is a new message on a Telegram Public Channel.

- Can search for whole words or text strings.
- Can distinguish upper and lower case.
- Keywords are not case sensitive.
- You don't need to register a Telegram bot.
- You don't need to subscribe to the channel

This is a trigger: it starts the task. A task has exactly one.

## Fields you set

The field's internal name, its type and the values it accepts. These fields accept `{{...}}` tags from earlier steps.

- `channel_link` *(string)* — Public Channel link

It also accepts repeatable field groups, with these prefixes: `filter_*`. These are composite components (buttons, filters, keyboards); the trailing number is set by the user as they are added.
