## Description

**WebCallHub** adds a professional click-to-call widget to your WordPress site. 
When visitors click the call button, they connect directly to your support team 
through their browser using WebRTC technology.

**No phone lines. No hardware. No apps to install.**

#### How It Works

 1. Visitors see a call button on your website
 2. They click it and enter their name
 3. Their browser connects directly to your support agent’s browser
 4. You talk — just like a phone call, but through the web

 * **AI Receptionist** — AI answers calls 24/7, qualifies leads, books appointments

   7

### External services

This plugin relies on the WebCallHub service to provide browser-to-browser click-
to-call functionality. WebCallHub is operated by HSG IT USA LLC (Austin, TX, USA)
and HSG IT Services Oy (Finland), the same company that distributes this plugin.

The plugin communicates with the WebCallHub service at `app.webcallhub.com` in two
ways:

**1. Loading the call widget script (`app.webcallhub.com/api/widget.js`)**

 * What it is: The JavaScript file that renders the click-to-call button and handles
   the WebRTC voice call.
 * When it is sent: On every front-end page view where the widget is enabled and
   a Site Key is configured.
 * What data is sent: Your configured Site Key (passed as the `siteId` query parameter)
   plus the standard HTTP request metadata the visitor’s browser sends to any external
   script host (IP address, user agent, referring page). No visitor form data is
   submitted by the plugin itself.
 * Why: The widget UI and the call session must be served by the WebCallHub service
   in order to establish a voice call.

**2. Domain handshake on Site Key save (`app.webcallhub.com/api/widget/wp-handshake`)**

 * What it is: A one-time `POST` request sent from your WordPress server to the 
   WebCallHub backend when you save a new Site Key in the plugin settings, or when
   the plugin is re-activated with a Site Key already configured.
 * What data is sent: Your Site Key, your WordPress site URL (`home_url()`), and
   the plugin version. No visitor data is sent.
 * Why: WebCallHub uses this handshake to verify that the WordPress install at the
   claimed domain is actually running the plugin, so it can auto-mark your site 
   as domain-verified in the WebCallHub dashboard.

Any voice call audio, visitor name, or transcript data is exchanged directly between
the visitor’s browser and the WebCallHub service (not via this plugin’s PHP code)
and is governed by WebCallHub’s own privacy policy.

### Is it free?

The plugin is free. WebCallHub has a Free plan (30 min/month, 1 agent) that lasts
forever — no credit card required. Paid plans start at $19/month (Starter) for more
minutes, agents, and features like transcription and call recording.

### Does it work on mobile?

Yes! Both visitors and support agents can use WebCallHub on mobile devices. Agents
can even install it as a phone app to receive call notifications.

### Can I use it on multiple WordPress sites?

Yes! Each WordPress site needs its own Site Key from your WebCallHub dashboard. 
Pro and Enterprise plans support unlimited sites.

Yes. You can configure the widget position, colors, and greeting text from your 
WebCallHub dashboard. The WordPress plugin lets you control which pages show the

## Changelog

#### 1.2.2

 * Changed: widget now loads from the static CDN endpoint (webcallhub.com/embed/
   widget.js) with configuration passed via data attributes instead of URL parameters.
 * Improved: the Site Key field accepts either the dashboard site key or your workspace
   slug — both resolve to your account.
 * Fixed: position, color, and greeting settings are now applied to the widget (
   previously ignored by the loader).

#### 1.2.1

 * Fixed: added a “translators:” comment on the plugin-version `printf()` call (
   Plugin Check `WordPress.WP.I18n.MissingTranslatorsComment`).
 * Fixed: escaped the `WEBCALLHUB_VERSION` constant when echoed on the settings 
   screen (Plugin Check `WordPress.Security.EscapeOutput.OutputNotEscaped`).
 * Fixed: trimmed the readme tag list from 7 entries to 5 (Plugin Check `readme_parser_warnings_too_many_tags`).

#### 1.2.0

 * Switched widget script loading to `wp_enqueue_script` with async strategy (previously
   output via direct `<script>` echo).
 * Renamed main plugin class from `WebCallHub` to `WebCallHub_Plugin` so it shares
   the `webcallhub` prefix used throughout the plugin.
 * Added explicit “External services” section in the readme documenting every call
   made to `app.webcallhub.com`, with links to the Terms of Service and Privacy 
   Policy.

#### 1.1.0

 * Fixed: text domain now matches plugin slug across all gettext calls.
 * Fixed: contributor username corrected; Stable tag synced with plugin header.
 * Removed: external promotional links from public-facing pages.
