The Send a Slack Message step posts a message to one or more Slack channels during a deployment or runbook run. You can use it to notify your team when a deployment succeeds or fails, or at any point in your deployment process.
The Send a Slack Message step is available from Octopus Server version 2026.3.5228.
You can add this step to a process at any time. If a Slack workspace isn’t connected yet, the step editor shows a prompt to set one up. See Slack integration for instructions.
