# Clay Hello World

## Overview

Minimal working example: send a company domain to a Clay table via webhook, let Clay's enrichment columns fill in company data, and retrieve the enriched result. Clay does not have a traditional SDK — you interact with it via webhooks (data in), HTTP API columns (data out), and the web UI.

## Prerequisites

- Completed `clay-install-auth` setup
- Clay workbook with a webhook source configured
- At least one enrichment column added to the table

## Instructions

### Step 1: Create a Clay Table with Enrichment

In the Clay web UI:

1. Create a new workbook
2. Add columns: `domain`, `company_name`, `employee_count`, `industry`
3. Click **+ Add** at bottom, select **Webhooks > Monitor webhook**
4. Copy the webhook URL
5. Add an enrichment column: **+ Add Column > Enrich Company** (uses the `domain` column as input)

### Step 2: Send Your First Record via Webhook

```bash
# Send a single company domain to your Clay table
curl -X POST "https://app.clay.com/api/v1/webhooks/YOUR_WEBHOOK_ID" \
  -H "Content-Type: application/json" \
  -d '{"domain": "openai.com"}'
```

Within seconds, Clay creates a new row and auto-runs the enrichment column. The `company_name`, `employee_count`, and `industry` columns fill in automatically.

### Step 3: Send Multiple Records

```bash
# Batch send — each object becomes a row
for domain in stripe.com notion.so figma.com linear.app; do
  curl -s -X POST "https://app.clay.com/api/v1/webhooks/YOUR_WEBHOOK_ID" \
    -H "Content-Type: application/json" \
    -d "{\"domain\": \"$domain\"}"
  echo " -> Sent $domain"
done
```

### Step 4: Send from Node.js

```typescript
// hello-clay.ts — send records to Clay via webhook
const CLAY_WEBHOOK_URL = process.env.CLAY_WEBHOOK_URL!;

interface LeadInput {
  email?: string;
  domain?: string;
  first_name?: string;
  last_name?: string;
  linkedin_url?: string;
}

async function sendToClay(lead: LeadInput): Promise<Response> {
  const response = await fetch(CLAY_WEBHOOK_URL, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(lead),
  });

  if (!response.ok) {
    throw new Error(`Clay webhook failed: ${response.status} ${response.statusText}`);
  }
  return response;
}

// Send a test lead
await sendToClay({
  email: 'jane@stripe.com',
  first_name: 'Jane',
  last_name: 'Doe',
  domain: 'stripe.com',
});
console.log('Record sent to Clay — check your table for enriched data.');
```

### Step 5: Send from Python

```python
import requests
import os

CLAY_WEBHOOK_URL = os.environ["CLAY_WEBHOOK_URL"]

def send_to_clay(lead: dict) -> requests.Response:
    """Send a lead record to a Clay table via webhook."""
    response = requests.post(
        CLAY_WEBHOOK_URL,
        json=lead,
        headers={"Content-Type": "application/json"},
    )
    response.raise_for_status()
    return response

# Test it
send_to_clay({
    "email": "jane@stripe.com",
    "first_name": "Jane",
    "last_name": "Doe",
    "domain": "stripe.com",
})
print("Record sent to Clay — check your table for enriched data.")
```

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `404 Not Found` | Invalid webhook URL | Re-copy URL from Clay table settings |
| `422 Unprocessable` | Invalid JSON payload | Validate JSON structure before sending |
| Row appears but no enrichment | Enrichment column not configured | Add enrichment column in Clay UI, enable auto-run |
| `429 Too Many Requests` | Exceeded webhook rate limit | Add 100ms delay between requests |
| Webhook limit reached (50K) | Webhook exhausted | Create a new webhook source on the table |

## Output

- New row(s) visible in your Clay table
- Enrichment columns auto-populated with company/person data
- Console confirmation of successful webhook delivery
