+# HubSpot lead capture (GitHub Pages)
+
+The demo form on `agende-demonstracao.html` submits leads via HubSpot's **public** form
+integration endpoint (`portalId` + `formGuid`). A **private** HubSpot API key must **never**
+ship in this repository or in browser JavaScript.
+
+## GitHub Actions secrets
+
+In **DataBoar/data-boar-site** → Settings → Secrets and variables → Actions, set:
+
+| Secret | Description |
+| ------ | ----------- |
+| `HUBSPOT_PORTAL_ID` | HubSpot account portal ID |
+| `HUBSPOT_DEMO_FORM_GUID` | GUID of the "Agendar demonstração" form |
+| `HUBSPOT_REGION` | Optional; default `na1` (use `eu1` for EU portals) |
+
+The workflow `.github/workflows/pages-deploy.yml` writes `js/form-config.js` from these
+secrets at deploy time only.
+
+## Enable Actions-based Pages deploy
+
+1. Settings → Pages → Build and deployment → Source: **GitHub Actions**
+2. Merge a PR that includes `pages-deploy.yml`
+3. Confirm the workflow run injects config and publishes the site
+
+Until secrets exist, the form shows a **mailto fallback** (`contact@databoar.com.br`) instead
+of failing silently.
+
+## HubSpot form field mapping
+
+Align the HubSpot form with these `name` attributes (see `js/forms.js`):
+
+| Form label (PT) | HubSpot property |
+| --------------- | ---------------- |
+| Nome completo | `firstname` + `lastname` (split on first space) |
+| E-mail corporativo | `email` |
+| Empresa | `company` |
+| Cargo | `jobtitle` |
+| Telefone | `phone` |
+| Segmento + desafio + data | combined in `message` |
+
+Custom HubSpot properties require updating the field list in `js/forms.js`.
+
+## Login page
+
+`login.html` does not send credentials to HubSpot. Submit shows an "em breve" message and
+points visitors to the demo form until product SSO is wired.
+
+## Out of scope (operator only)
+
+- DNS, Cloudflare, custom domain, MX records
+- Storing private HubSpot app tokens in the repo
