SendGrid Mailer

Endpoints

POST /api/contact

Public contact-form endpoint for static sites. Uses honeypot validation, optional Origin allowlist, and fixed to/from addresses.

POST /api/sendmail?code=<function-key>

General mail API for trusted callers. Requires function-level authentication (authLevel: function).

About

The API sends email using the Node.js @sendgrid/mail SDK (api.sendgrid.com by default). The SendGrid API key is stored server-side — static sites call /api/contact only and never receive mail credentials.

/api/sendmail supports to, from, subject, contentHtml, contentText, and attachments. /api/contact accepts name, email, subject, message, and honeypot website.

Usage notes

• POST /api/contact is for blob-hosted contact forms; recipient and sender are server-controlled.
• POST /api/sendmail requires ?code=<function-key> or x-functions-key.
• Defaults to noreply@louwmangroup.nl for from and online@louwmanictservices.nl for contact inbox delivery.
• Set ALLOWED_ORIGINS to restrict which site origins may call /api/contact.
• GET /api/health returns {"status":"ok"} for pipeline health checks.
• CAPTCHA (Turnstile/reCAPTCHA) is planned for a future release.

Try it

curl -X POST "http://localhost:7071/api/contact" \
  -H "Content-Type: application/json" \
  -H "Origin: http://localhost:7071" \
  -d '{"name":"Test","email":"test@example.com","subject":"Hi","message":"Hello","website":""}'
