Vanilla JS / HTML

For a static site or no framework. Two <script> tags are enough:

<script src="https://supportdesk-widget.vercel.app/v1/supportdesk-widget.js"></script>
<script>
  SupportDesk.init({
    appId: 'your-app-id',
    apiKey: 'pk_live_xxxxxxxxxxxx',
    customer: {
      externalId: 'user-123',
      email: 'user@example.com',
      name: 'John Doe',
    },
    theme: {
      primaryColor: '#2563eb',
      position: 'bottom-right',
    },
  });
</script>

Without a logged-in user

Simply omit the customer field:

SupportDesk.init({
  appId: 'your-app-id',
  apiKey: 'pk_live_xxxxxxxxxxxx',
});
