Send workflow failure details to a Slack channel.

[在 Open Flow 中使用](https://console.openflow.run/flows?importUrl=https%3A%2F%2Fraw.githubusercontent.com%2Foomol-lab%2Fawesome-workflow-templates%2F9018120e802d4de0a097610157c565df858c0871%2Fworkflows%2Fnotify-workflow-failures-on-slack%2Ftemplates%2Fnotify-workflow-failures-on-slack.openflow.json)

Send workflow failure details to a Slack channel.

## Setup

Connect Slack with permission to post in the destination channel. In Open Flow, set its channel ID on **Send Slack alert**, select the published source workflows in **Receive a workflow failure**, then publish and enable this workflow. In n8n, select the channel and connect Slack on **Slack**, enable this workflow, and choose it as the error workflow in each source workflow’s settings. Enable one format. Avoid assigning the error workflow to itself.

## Behavior

An automatic workflow failure sends its workflow name, execution reference, failed node and error message to Slack. Open Flow sends the run ID and, when available, the node ID. n8n sends the execution URL and last node name. Missing details are shown as not available.

Error messages can contain sensitive information. Restrict access to the channel and workflow history. Open Flow stops before sending if the alert exceeds 40,000 characters; Slack may reject oversized messages in either format. A failed or uncertain send may already have been delivered; inspect the channel before retrying.

Inspiration & credits

## Changes to the source

*   Configure the Slack channel and bind the relevant source workflows through each platform’s error trigger. Open Flow reports its run ID and node ID instead of n8n’s execution URL and node name.
*   Escape Slack control characters in error details to prevent them from becoming channel or user mentions.
