# Instantly when receiving a new post on any public #channel — Slack

Botize method — `slack.webhook` (trigger).

Triggers instantly when a user posts a message in any public Slack 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.

- `type` *(string, one of: "any"; "command")* — Type of message source. Determines if any text from users or only texts with specified command are accepted
- `command` *(string)* — Command. Command text to match if 'type' is 'command'

*(Fields derived from the configuration form.)*

## Output variables

Data this step makes available. Reference them in later steps with the double-brace tag.

- `{{from_id}}` *(text)* — From User Id
- `{{channel_id}}` *(text)* — From Channel Id
- `{{text}}` *(text)* — User message
