# 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

The first run confirms receipt of a controlled test row and returns only a
redacted status/correlation value. A successful webhook acknowledgement does
not confirm enrichment quality, lawful data use, or CRM publication; inspect
the authorized staging table and configured conditions before taking the next
step.

## Examples

Send a synthetic or explicitly approved test record to a staging webhook, log
the response status without the webhook URL or personal data, and verify that
the resulting row is subject to the intended enrichment conditions. If the
endpoint returns 4xx/5xx, stop instead of creating new webhooks or resending
the record until the configuration is corrected.
