Notify Slack When a Workflow Fails

Send a Slack alert when a configured workflow fails.

Setup

In Open Flow, select the published source workflows in Receive a workflow failure, publish and enable this workflow, connect Slack, and set the destination channel ID. In n8n, connect Slack, set the destination channel, and assign this workflow as the error workflow in each source workflow’s settings. Do not assign the workflow to itself.

Behavior

An automatic failure sends an alert containing the workflow name. Open Flow includes the run ID; n8n includes the execution URL when available. Open Flow does not supply an execution URL in its error event. Manual test runs do not represent automatic failure dispatch.

If a send fails or its outcome is uncertain, check Slack before retrying; the alert may already have been delivered.

Inspiration & credits

Changes to the source

Configure the previously empty Slack channel and bind source workflows. Open Flow reports a run ID instead of the n8n execution URL.
