Send Notification
Post an alert to Slack or a webhook when an upstream branch fires.
Posts a message to a webhook or a Slack channel when the flow reaches it.
Every in-port is required, which is what makes this fire only when something upstream actually emitted: a Conditional branch that did not match never produces its port, so the alert never sends. Unconnected ports are invisible to that check, which is why three kinds can coexist here — wire the one that suits, leave the others alone.

Rows to render into messageTemplate.
payload

yes
A JSON body to render, or to send as-is when includePayload is set.
trigger
