How Trello and Slack work together

Trello and Slack work together in two broad patterns.


#1 Works with the Trello app

You can add Trello to Slack by adding an app.
Run the Trello command in Slack. Basically, this is for those who want to use Slack as a main machine.

#2 Works with Trello Alerts

Let us explain #1. Click “+” next to App in the left menu of Slack My Page.

This will take you to the Trello introduction page below.

Once it’s working, you’ll see that Trello has sent a notification to Slack.

The message includes a link announcement and a tutorial on how to use it.

If you are in trouble, you can open the channel of TrelloBot and check the command list above.
