Slack

Configure a workflow step that posts a message to a Slack channel using a connected Slack account

Use Slack when you want a workflow step to post a message to a Slack channel from a connected workspace integration.

Configuration

Option	Required	Description
Name	No	Label for the step in the workflow canvas.
Integration Authorization	Yes	The connected Slack account selected in Authentication.
Action	Yes	The Slack action. The current editor shows Send Channel Message.
Channel	Yes	Channel name entered in Channel.
Message	Yes	Message body entered in Message.
When the step fails	No	Controls whether the workflow should Terminate Workflow or Continue if this step fails.
Before you configure this step, connect Slack in Integrations for your workspace. If no active Slack connection is available, the step shows a warning with a link to Integrations instead of the account selector.

Use the Insert Variable button next to Channel and Message if either value should come from start inputs or earlier workflow steps.

Output

This step stores the Slack API response from the posted message as the step output.

Use the full output reference in later steps:

{{STEP_IDENTIFIER.output}}

If you need a specific field from the returned Slack payload, insert it from the variable picker after a test run:

{{step_2.output.some_field}}

The available keys depend on the Slack response returned for that message run.

Example

Open Integrations and connect Slack if you have not already done that.

Add Slack to your workflow and choose a connected account in Authentication.

Keep Action set to Send Channel Message.

Enter the destination in Channel, such as general, then write the Slack post in Message. You can insert values like {{step_1.output}} into the message body.

Click Run in the step header to test the message, then review the returned payload in Output if you want to pass any of that data to a later step.

Notes

• This step depends on a connected Slack integration in your workspace.

• The channel field uses the channel name, not a full Slack URL.

• The current editor exposes one Slack action: Send Channel Message.
