 ## Technique 2: Slack App
 
 By creating a new Slack app or using an existing one, this approach allows your GitHub Actions job to post a message in a Slack channel or direct message by utilizing the [chat.postMessage](https://api.slack.com/methods/chat.postMessage) API method. Using this approach you can instantly post a message without setting up Slack workflows.
