Demo showing how to enrich new user signups from a Hubspot Form.

The data passes from Hubspot form -> Hubspot webhook (new contact creation) -> Clay for enrichment -> send notifications to Slack.

• slack.ts - Send Slack notification
• test.ts - Test script to simulate new user sign up
• webhook.ts - Receives webhooks when you get a new user

1. Remix this val
2. Get a Slack webhook & set it as SLACK_WEBHOOK_URL in this val's Environment variables in the left sidebar
3. Get a random token & set it to VAL_WEBHOOK_SECRET in this val's Environment variables in the left sidebar
4. Click run on test.ts to see the complete flow (takes up to 5 minutes to enrich)
5. Check your Slack channel for the enriched user notification
6. Set your auth system (ie Clerk) to send new user webhooks to webhook.ts

Clay is a user-enrichment tool that allows you to leverage the data of hundreds of enrichment services.

We at Val Town have set up a basic Clay enrichment table that finds basic user info from email address or github username – and have created a synthetic API to it, which this val calls. Clay costs money, so proxy is only available to paid Val Town Teams accounts.

As of Aug 2025, Apps on Hubspot's new developer platform need to be done via the CLI

1. Install the HubSpot CLI with these instructions
   • Here were the steps that worked for me in the CLI:
     • npm install -g @hubspot/cli@latest
     • hs account auth
     • hs project create for an App, with Private distribution, Static Auth and Webhooks
2. In your new src/app directory, add webhooks/webhook-hsmeta.json with the following config.

Note: Swap out the targetUrl with your Val Town HTTP endpoint URl from ./webhook.ts.

{
  "uid": "webhooks",
  "type": "webhooks",
  "config": {
    "settings": {
      "targetUrl": "https://charmaine--0199720fd819701cb2e80be3c8cff217.web.val.run",
      "maxConcurrentRequests": 10
    },
    "subscriptions": {
      "crmObjects": [
        {
          "subscriptionType": "object.propertyChange",
          "objectType": "contact",
          "propertyName": "email",
          "active": true
        }
      ]
    }
  }
}

3. Upload the Hubspot project by running hs project upload in your terminal.
4. You can find the project and the associated webhook you just uploaded in Hubspot under Development > deployed build > webhooks
5. Once you have this hooked up alongside your new form (instructions to host on Val Town), you can test the end-to-end submission flow from the Hubspot form -> get enriched user information in Slack.
