SLACK

Post a message to a Slack channel via incoming webhook. Content supports templates.

Deprecated since 2026-09-04 — use SLACK_POST instead.

A webhook URL is pinned to one channel and is stored in plain node config. Slack Post Message uses the workspace credential, can post to any channel, and keeps the token out of the run trace. Existing workflows using this node keep working; it is only unavailable for new ones.
