Automatic identity

The loader reads window.whazzupSettings when it starts, so no manual call is needed. Set it before the script tag, or update it from your app at any time.

window.whazzupSettings = {
  name: 'Ada Lovelace',
  email: 'ada@example.com',
  userId: '42',
  plan: 'pro'
}

Known keys are name, email, company, userId and token. Every other simple value is stored as a custom attribute.

Whazzup detects a changed stable user ID or email and rotates the local session. Explicitly call reset before an in-app account switch, and logout when the person signs out. Both commands invalidate the old session and prevent conversation history crossing account boundaries.

// Before switching to another account
window.whazzup('reset')
window.whazzupSettings = nextUser

// On logout
window.whazzupSettings = null
window.whazzup('logout')
