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.

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.
