Quick start

Installation

Add the following code to your website:

  var RSConfig = {
    type: 'location_services',
    slug: 'your-location-slug',
  };
  !(function (b, c, d) {
    var a,
      e = b.getElementsByTagName(c)[0];
    b.getElementById(d) ||
      (((a = b.createElement(c)).id = d),
      (a.src = 'https://js-widget.reservation.studio/v2/widget.min.js'),
      e.parentNode.insertBefore(a, e),
      (a.onload = function () {
        window.RSWidget(RSConfig);
      }));
  })(document, 'script', 'rs-booking-widget-js');
</script>

Request parameters

Pass additional parameters using parameters:

var RSConfig = {
  type: 'location_services',
  slug: 'your-location-slug',
  parameters: {
    category: '123',
    services: '123,124',
  },
};

Supported parameters:

Parameter	Type	Description	Example
category	string	Displays a category	'123'
services	string	Comma-separated list of service IDs to preselect	'123,124'

UTM parameters

Track marketing campaigns with the utm options:

Option	Type	Description
source	string	Traffic source
medium	string	Traffic medium
campaign	string	Campaign name
content	string	Content identifier
term	string	Search term

The widget automatically detects UTM parameters from the page URL (utm_source, utm_medium, etc.) and stores them in local storage. They are used for all widget interactions until they expire (default: 1 hour). If no UTM parameters are present, the widget uses defaults source: 'reservation.studio', medium: 'js-widget'.

Advanced usage

Custom trigger buttons

Use buttons_selector to specify which elements should open the widget on click:

<!-- HTML -->
<button class="open-booking-widget">Book now</button>

<!-- JavaScript config -->
<script>
  var RSConfig = {
    type: 'location_services',
    slug: 'your-location-slug',
    buttons_selector: '.open-booking-widget',
  };
</script>

Selectors can target elements by class, ID, tag name, or complex CSS selectors.

Note: Elements must exist when the widget initializes. Dynamically added elements may not work as expected.

Dynamic configuration with data attributes

Customize widget behavior for specific buttons using data attributes:

<!-- Different location -->
<button class="open-booking-widget" data-slug="location2">
  Book at Location 2
</button>

<!-- Different language -->
<button class="open-booking-widget" data-language="en">Book in English</button>

<!-- Custom UTM parameters -->
<button
  class="open-booking-widget"
  data-utm='{"source":"newsletter","medium":"email"}'
>
  Book from newsletter
</button>

<!-- Filter by category -->
<button class="open-booking-widget" data-parameters-category="123">
  Book by category
</button>

<!-- Filter by services -->
<button class="open-booking-widget" data-parameters-services="123,124">
  Book specific services
</button>

For request parameters, use the form data-parameters-{name} where {name} is the parameter name. Nested parameters can be expressed by chaining names with hyphens.

Note: The slug, language, utm, and request parameters (via data-parameters-*) can be overridden via data attributes.
