# Technique 3: Slack incoming webhook

This technique uses this Action to post a message to a channel or direct message
with [incoming webhooks][incoming-webhook] and a Slack app.

Incoming webhooks follow the same [formatting][formatting] patterns as other
Slack messaging APIs. Posted messages can be as short as a single line of text,
include additional interactivity with [interactive components][interactivity],
or be formatted with [Block Kit][block-kit] to build visual components.

## Setup

For details on how to setup this technique in GitHub Actions, read the [setup][setup] section of the docs.
