The Slack Message node sends automated messages to Slack channels as contacts pass through a workflow. Use it to alert sales reps about high-intent leads, notify customer success teams of lifecycle changes, or push real-time updates to any channel your team monitors.

​
Prerequisites

You must connect your Slack workspace before using this node. See Slack integration for setup instructions.

​
Configuration

If the channel you are looking for isn’t appearing in the dropdown, you can paste in the Channel ID (found under the channel Settings → About) into the search bar.

Dynamic values in messages

Type / in the message field to open the command menu and insert liquid expressions, contact fields, or tokens. Values resolve at runtime with the contact’s current data.
Text inputs in this node support Liquid templating. Type / to choose from Add liquid, Add a field, or Add a token to insert dynamic values.
Example message:
Any CRM-mapped, custom, or system field is available for insertion. If a field has no value for a given contact, that portion of the message is simply omitted — no errors or formatting breaks occur.
Opportunity data isn’t available through Add a field — opportunity fields can only be referenced via Liquid. To insert the most recent opportunity’s name, amount, or stage, choose Add liquid and use the company._opportunities object. See Opportunities in Liquid for the full syntax and an example Slack message.

​
Behavior

  • The node sends one Slack message per contact that passes through it.
  • Messages are sent immediately when the contact reaches the node (subject to any upstream delays).
  • If the Slack workspace is disconnected or the channel no longer exists, the message fails silently and the contact continues to the next node.
