Post messages to Slack channels
The Slack step sends a message to a connected Slack channel. You provide the message content, and the step outputs a direct link to the posted message. Requires a connected Slack integration with a selected channel.
The step reads an input (message) field from its input record and posts it to the configured Slack channel. The channel is specified via channelId in the slackConfig. Outputs {message_url, success, error} with a link to the posted message.
