Web Widget

Embeddable JavaScript widget for purchasing e-vignettes directly on your website. The widget handles the entire purchase flow: country selection, vehicle type, duration, vehicle details, and payment.

Quick Start

Add the widget to any webpage with just few lines of code:

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
    apiUrl: 'https://api.vignette.id',
    locale: 'uk',
    currency: 'EUR',
  });
</script>

Installation Methods

Script Tag (Recommended)

Code
<script src="https://widget.vgnt.app/vignette-widget.js"></script>

Dynamic Injection (Console / Programmatic)

Code
(function(){
  var d = document.createElement('div');
  d.id = 'vw-' + Date.now();
  document.body.appendChild(d);
  var s = document.createElement('script');
  s.src = 'https://widget.vgnt.app/vignette-widget.js';
  s.onload = function(){
    VignetteWidget.init({
      container: '#' + d.id,
      apiKey: 'YOUR_API_KEY',
      apiUrl: 'https://api.vignette.id',
      locale: 'uk',
      currency: 'EUR',
      position: 'bottom-right',
      fabLabel: 'Buy Vignette',
    });
  };
  document.head.appendChild(s);
})();

Configuration

VignetteWidget.init(config)

Position Modes

inline (default)

The widget renders directly inside the container element, embedded in the page flow.

Code
VignetteWidget.init({
  container: '#vignette-widget',
  apiKey: 'YOUR_API_KEY',
  position: 'inline',
});

bottom-right / bottom-left

The widget appears as a floating button (FAB) in the corner of the screen. Clicking the button opens the widget panel.

Code
VignetteWidget.init({
  container: '#vignette-widget',
  apiKey: 'YOUR_API_KEY',
  position: 'bottom-right',
  fabLabel: 'Buy Vignette',
});

Supported Countries

Countries without available products are automatically hidden from the list.

Registration Countries

The plateCountry option accepts any of the following ISO codes (passed lowercase). The same list is also shown in the step-4 registration-country <select> inside the widget, so prefilling matches what the user would see manually.

Codes include all EEA countries plus a wide set of non-EU origins (UA, TR, GE, UZ, KZ, etc.) to cover foreign-registered vehicles transiting through.

Purchase Flow

The widget guides users through 5 steps:

1. Country — Select one or multiple countries (multi-select)
2. Vehicle Type — Car, Van, or Motorcycle (filtered by selected countries)
3. Duration — Choose vignette period per country with start date picker
4. Vehicle Info — License plate, registration country, email (VIN for RO/MD, passport for MD)
5. Summary — Order review with total price and payment

Input Validation

• License plate: Latin letters, digits, and spaces only. Dash (-) allowed for Austrian and German plates
• Cyrillic characters are blocked with an error message prompting to switch keyboard language
• Extended Latin characters (e.g. ü, á, ș) are blocked with a specific error message
• Email: ASCII characters only
• VIN: 17 alphanumeric characters (excluding I, O, Q)

Payment

After clicking "Pay", the widget creates an order via the API and displays the payment page (Stripe) inside an iframe. Upon successful payment, the user is redirected to a success page.

Payment Redirect URLs

Configure these URLs in your Vignette ID partner dashboard:

Code
SUCCESS REDIRECT URL:  https://widget.vgnt.app/payment/success
ERROR REDIRECT URL:    https://widget.vgnt.app/payment/error

Callback

Use onComplete to handle the order result in your application:

Code
VignetteWidget.init({
  container: '#vignette-widget',
  apiKey: 'YOUR_API_KEY',
  onComplete: function(order) {
    console.log('Payment link:', order.payment_link);
    console.log('Order ID:', order.order_id);
    // Redirect or show custom UI
    window.location.href = order.payment_link;
  },
});

When onComplete is provided, the widget will call it instead of showing the payment iframe.

Environments

Sandbox Test Card

Code
Card number: 4242 4242 4242 4242

Examples

Minimal (Inline)

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
  });
</script>

Floating Widget with Filtered Countries

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
    locale: 'en',
    currency: 'EUR',
    position: 'bottom-right',
    fabLabel: 'Buy Vignette',
    countries: ['at', 'ch', 'si', 'hu'],
  });
</script>

Dark Theme

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
    theme: 'dark',
  });
</script>

Pre-selected Registration Country

When you know most of your traffic comes from one origin country (e.g. Ukrainian drivers on a UA site), pre-fill the registration-country field so users skip one click.

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
    plateCountry: 'ua',
  });
</script>

Pre-filled Plate & VIN (rental flow)

When the partner already has the vehicle data — for example, a car-rental site that knows the customer's booked car — pass plate and vinCode so step 4 is fully prefilled and the user only confirms.

Code
<div id="vignette-widget"></div>
<script src="https://widget.vgnt.app/vignette-widget.js"></script>
<script>
  VignetteWidget.init({
    container: '#vignette-widget',
    apiKey: 'YOUR_API_KEY',
    plateCountry: 'at',
    plate: 'W-12345X',
    vinCode: 'WVWZZZ3CZWE123456',
  });
</script>

plate is filtered the same way as user-typed input — dashes are kept only for at and de, and any Cyrillic / extended-Latin / non-allowed characters are stripped (with a console.warn so you can see what got dropped). vinCode is uppercased, truncated to 17 chars, and any I/O/Q (or other forbidden chars) are removed.

Lifecycle

init() returns a handle object with a destroy() method. Call it when you tear the widget down — SPA route changes, conditional rendering, modal close — to free resources.

Code
const widget = VignetteWidget.init({
  container: '#vignette-widget',
  apiKey: 'YOUR_API_KEY',
});

// later
widget.destroy();

destroy() clears the shadow DOM, removes the internal postMessage listener for payment callbacks, and cancels any pending rate-limit retry timers. Safe to call multiple times.

Without destroy(), repeated init() calls on the same page accumulate postMessage listeners on window — harmless but leaky.
