# Classify new Gmail messages with AI and route them

**Use case:** 

Generates an n8n workflow with a Gmail Trigger, an AI Text Classifier on an OpenAI chat model that labels each email invoice, support or other, a Google Sheets append for invoices and a Slack post for support emails. The classifier's categories and the branch wiring are set from n8n's own definitions. Attach Gmail, OpenAI, Google Sheets and Slack credentials after import.

## Input

```json
{
  "prompt": "When a new email arrives in Gmail, classify it with an AI text classifier into 'invoice', 'support' or 'other'. Invoices go to a Google Sheet, support emails are posted to Slack, others are ignored."
}
```

## Output

```json
{
  "workflowName": {
    "label": "Workflow",
    "format": "text"
  },
  "valid": {
    "label": "Valid",
    "format": "boolean"

## 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. Visit the [Actor detail page](https://apify.com/mediocre_interest/n8n-workflow-builder.md) to learn more, explore other use cases, and run it yourself.


## 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`).
