SendGrid Mailer

Lightweight Azure Functions endpoint that delivers email through the SendGrid API. Useful for notifications, test emails, and scripted delivery with optional attachments.

Typical API response

HTTP 200 · application/json

{"status":"sent","messageId":"abc123..."}

Each successful request delivers one email via SendGrid.

Endpoint

POST /api/sendmail

Phase 1 uses authLevel: anonymous for testing. Phase 2 will require ?code=<function-key>.

About

The API sends one email per request using the Node.js @sendgrid/mail SDK (api.sendgrid.com by default). The SendGrid API key is stored server-side and passed as a Bearer token — callers never supply it.

Supported JSON fields: to, from, subject, contentHtml, contentText, and attachments (base64-encoded).

Usage notes

POST /api/sendmail sends one email with the supplied or default values.
Defaults to noreply@louwmangroup.nl for from and online@louwmanictservices.nl for to when omitted.
At least one of contentHtml or contentText is required.
Attachments are passed as base64 in the JSON body (filename + content).
Phase 1 uses authLevel: anonymous on /api/sendmail for easy testing.
GET /api/health returns {"status":"ok"} for pipeline health checks.

Try it

curl -X POST "http://localhost:7071/api/sendmail" \
  -H "Content-Type: application/json" \
  -d @test/sample-payload.json
