  • ▸A signing secret (optional but recommended)
  • ▸Free Requex.me workspace

Setup

  1. 1

    Generate a Requex webhook URL

    Open Requex.me, copy the URL.

  2. 2

    Wire your source to send webhooks

    Point Zendesk, your contact form, Intercom — anything that emits webhooks — at the Requex URL.

  3. 3

    Load the template

    Workflows tab → load the AI classify template. Five nodes pre-wired.

  4. 4

    Configure the AI Classify node

    The node ships with three categories: urgent, billing, generic. Edit the labels to match your team. The AI runs on the included free tier — no OpenAI API key required.

  5. 5

    Set email routing

    Click the Switch node. Each branch ends in an Email node — set the recipient address per category (e.g. urgent → oncall@, billing → finance@, generic → support@).

  6. 6

    Test with a sample payload

    Use Requex's request replay feature: send a test payload, watch the AI classification in the run trace, and confirm the email arrives at the right address.

Why Requex for this

Zapier charges per task — every AI step counts. n8n requires you to bring your own OpenAI key with its own billing. Requex includes AI Classify and AI Text nodes in the free tier with no separate API account.
