OCPP endpoint

wss://voltvik.askendal.com/ocpp/<chargePointId>   (subprotocol ocpp1.6 or ocpp2.0.1, Basic Auth)

Webhooks

An admin adds endpoints under Admin → Webhooks. Each event is POSTed as JSON and retried after 10 s, 1 min and 5 min if your endpoint does not answer 2xx.

Event	When
`session.started`	A charging session starts (OCPP 1.6J StartTransaction or 2.0.1 TransactionEvent Started)
`session.stopped`	A session ends, with kWh, cost and reason
`charger.status`	A charger changes status (Available, Charging, Faulted …)
`lead.created`	Someone submits a form on the website

POST your-url
X-Voltvik-Event: session.stopped
X-Voltvik-Signature: t=1793600000,v1=<hex HMAC-SHA256 of "t.body" with your signing secret>

{ "id": "…", "event": "session.stopped", "created_at": "…",
  "data": { "session_id": 1281, "charger_id": "CP-03", "kwh": 41.2, "cost": 229.07, "currency": "SEK", "reason": "EVDisconnected", … } }

// Verify in Node.js
const [t, v1] = sig.split(',').map(x => x.split('=')[1]);
const ok = crypto.createHmac('sha256', secret).update(t + '.' + rawBody).digest('hex') === v1;
