Send to Slack

Use this node to post a message to a Slack channel or user — for example, notifying a DevOps channel when a server device goes offline, or sending a direct message to an on-call engineer when a critical alarm fires.

• Message template — required. Content of the Slack message. Supports templatization — use ${metadataKey} and $[dataKey] to include dynamic values.
• Use system Slack settings — when enabled, uses the Slack bot token configured at the system level. When disabled, specify the Bot token directly in this node.
• Bot token — Slack API bot token (required when system settings are disabled).
• Conversation type — PUBLIC_CHANNEL, PRIVATE_CHANNEL, or DIRECT.
• Conversation — target Slack channel or user (identified by Slack ID/name).

1. Resolve the message content from the template using incoming message data and metadata.
2. Post the message to the configured Slack conversation via the Slack API.
3. Route via Success on delivery. Message data and metadata are not modified.
4. Route via Failure on unexpected error.
