# Technique 2: Slack API method

A [token][tokens], such as a bot or user token, must be used to call one of
[the Slack API methods][methods] with this technique.

## Setup

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

## Example workflows

1. [**Direct message the author**](#direct-message-the-author): Write to the
   Slack user with a matching email.
2. [**Invite a usergroup to channel**](#invite-a-usergroup-to-channel): Create a
   channel and invite members.

### Direct message the author

Send a direct message to the user that pushed the most recent commits.

This example uses the email of the pusher to find the user to send a message to.
