# Get a Slack alert when any n8n workflow fails

**Use case:** 

Generates an n8n error workflow: an Error Trigger that fires whenever a workflow in your instance fails, wired to a Slack node that posts the workflow name, the failed node and the error message to #alerts. Import the JSON, attach your Slack credential, then select it as the error workflow in each workflow's settings.

## Input

```json
{
  "prompt": "When any workflow in this n8n instance fails, send a Slack message to #alerts with the workflow name, the failed node and the error message."
}
```

## Output

```json
{
  "workflowName": {
    "label": "Workflow",
    "format": "text"
  },
  "valid": {
    "label": "Valid",
    "format": "boolean"
  },
  "nodeCount": {
    "label": "Nodes",
    "format": "number"
  },
  "nodeTypes": {
    "label": "Node types",
    "format": "array"
  },
  "credentialsNeeded": {

  "warnings": {

  },
  "errors": {

## About this Actor

This example demonstrates how to use [n8n Workflow Generator - Prompt to Importable JSON](https://apify.com/mediocre_interest/n8n-workflow-builder.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/mediocre_interest/n8n-workflow-builder.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
