Clay doesn't offer an API, but you can simulate an API via Val Town by listening to webhooks, enriching data in Clay, and having Clay send an HTTP request back when enrichment is complete.

This demo uses Clay like an API to automatically enrich new user signups and send notifications to Discord.

Here's an example:

Here's the underlying Clay Table (feel free to zoom in to see the exact setup for debugging):

This project uses the Hono framework with a clean, flat architecture:

├── enrichedUserWebhook.ts    # Receives enriched data from Clay
├── newUserWebhook.ts         # Receives new signups from Clerk/Stripe
├── discordNotifications.ts   # Discord message formatting and buttons
├── types.ts                  # TypeScript interfaces
├── test-signup.ts            # Test utility
├── main.tsx                  # Hono app entry point with routing
├── deno.json                 # Deno configuration
└── README.md                 # This file

1. Create a new Clay workbook called "New User Enrichment"

2. Click Add → Pull in data from source at the bottom

3. Select Pull in data from a Webhook Table

4. Click Edit source on the Webhook column to copy the webhook URL

5. Add the webhook URL to your environment variables:

   • Go to your val's Environment Variables
   • Add environment variable: CLAY_WEBHOOK_URL
   • Set value to: https://api.clay.com/v3/sources/webhook/pull-in-data-from-a-webhook-YOUR_ID

Note: Setting up the webhook like this lets you transform / filter the data before sending it over to Clay. It also helps with error handling and give you logs in Val Town for observability. Otherwise, you could set up the webhook directly from the source ie. Clerk, Stripe etc.

Add whichever enrichment columns you want. This example uses:

• Enrich Person → Name, Title, Org
• LinkedIn Profile → LinkedIn URL

1. Click Add Column → Add Enrichment → search for HTTP API
2. Add HTTP API column to your Clay table
3. Click Edit Column and fill in the following:

• Set endpoint to your HTTP URL: https://your-val-url.com/enrichedUserWebhook (Note: you need the /enrichedUserWebhook!)
• Set method: POST
• Configure request body:

{
  "email": "{{email}}",
  "profile_image_url": "{{profile_image_url}}",
  "Name": "{{name}}",
  "Title": "{{title}}",
  "Org": "{{org}}",
  "LinkedIn": "{{LinkedIn Profile}}"
}

• Enable Remove empty values
• Here's what my final column looked like:
• 

1. Click Environment Variables in your val's sidebar
2. Add the following environment variables:

Required:

• CLAY_WEBHOOK_URL - Your Clay webhook URL from step 1
• DISCORD_WEBHOOK - Your Discord webhook URL for notifications

This is what triggers a new row in the Clay table, hook up your source system (Clerk, Stripe, etc.) to send webhooks to your val's HTTP URL: https://your-val-url.com/newUserSignup (Note: you need the /newUserSignup!)

For Clerk, you can find it here:

This project integrates with this val for sending personalized outreach emails to new users.

When Clay enriches a user and sends the data back to Val Town, the Discord notification includes two interactive buttons:

1. ✉️ Preview & Send Email - Links to the external email service
2. ✏️ Edit Val - Quick link to edit this Val Town code

The "Preview & Send Email" button links to: https://send-lead-gen-email.val.run

This external service receives the enriched user data via URL parameters:

• name - The user's full name (if available)
• email - The user's email address
• title - The user's job title (if available)
• org - The user's organization (if available)

1. New user John Doe (CEO at TechCorp) signs up

2. Clay enriches the data with name, title, and company

3. Discord notification appears with enriched info

4. Clicking "Preview & Send Email" opens:

   https://send-lead-gen-email.val.run?name=John%20Doe&email=john@techcorp.com&title=CEO&org=TechCorp
   

5. The external service handles email preview, customization, and sending

Enriched profiles (with ⭐):

⭐ New user! John Doe • Software Engineer @ Tech Corp • john@example.com • https://linkedin.com/in/johndoe

Basic signups:

New user! user@example.org
