Slack (Actions) Destination

Destination Info

Additional versions of this destination are available

This page is about the Slack (Actions) Destination. See below for information about other versions of the Slack destination:

Slack is a team collaboration tool work flows. It’s where the people you need, the information you share, and the tools you use come together to get things done.

Benefits of Slack (Actions) vs Slack Classic

Slack (Actions) provides the following benefits over the classic Slack destination:

  • Consolidated Message Sending. Send multiple messages from a single instance of the Slack (Actions) destinations. Use Event Triggers to send a message when your criteria is met.
  • Streamlined Configuration. Configure connection details on a per-message basis, rather than for the destination as a whole. This enables sending messages to different workspaces or channels from one source.
  • Easier access to data. The event variables picker shows you all the available data from the event you use to test the Trigger. Variables are clearly labeled to ensure they stand out from other text and markup.

Getting Started

  1. From the Segment web app, click Catalog, then click Destinations.
  2. Find the Destinations Actions item in the left navigation, and click it.
  3. Click Configure Actions Slack.
  4. Select an existing Source to connect to Slack (Actions).
  5. Click Customized Setup to start from a blank mapping.
  6. In your Slack workspace, create a new Incoming Webhook URL and select the Slack channel associated with your account that you’d like to send messages to. The Slack channel you select will be the default channel that receives message events. Paste the Incoming Webhook URL you created into each of your Slack Destination’s Actions under the field labeled Webhook URL*.
