Session Lifecycle

Before you can 📤 Send or 📥 Receive messages you must:

Create a session (and optionally Start it) from https://wawp.net/account/connect.

Authenticate it by scanning a QR code or entering a pair-code in WhatsApp.

Status	Meaning & next step
STOPPED	Session is not running. Call Start to launch it.
STARTING	Engine is booting. Wait for the next status update.
SCAN_QR_CODE	WhatsApp needs a fresh login. • Fetch the latest QR each time you get this status (it changes frequently). • Display the QR (or pairing code) to the operator/user.
WORKING	Session is authenticated and ready to send/receive messages.
FAILED	Something went wrong (e.g., lost auth, device unlinked). • First try Restart. • If that fails, Logout and Start again to obtain a new QR.

  "status": "SCAN_QR_CODE",
  "qr": "data:image/png;base64,iVBORw0KGgoAAA...",
  "ts": 1722170400
}

Handle each new SCAN_QR_CODE event by replacing any previously shown QR/pair-code with the updated one.
