slashbooking

SlashBooking turns any WordPress page into a self-service appointment funnel. A visitor picks a service, sees the available slots in real time, and books in under a minute. You receive an email alert and confirm or decline in one click — no need to log in to WordPress, no third-party SaaS, no recurring fees.
It is a self-hosted scheduling tool: your data stays in your WordPress database.
<h4>Main features</h4>
<ul>
<li>Public booking form via shortcode — A single <code>[slashbooking]</code> in any page. Multiple services, date picker, real-time slots, customer form, fully responsive.</li>
<li>One-click email confirmation — Every request arrives with two buttons, Confirm and Decline. No WordPress login required. The action links are signed with HMAC-SHA256 and cannot be forged.</li>
<li>Smart buffers around appointments — Configure padding (travel, prep) between appointments. Applied automatically.</li>
<li>Multi-slot opening hours — Monday 9–12 + 14–18, Tuesday morning only, Wednesday off… Each day and each service is configured independently.</li>
<li>Transactional emails with .ics — Confirmation, decline and acknowledgement emails, each with an automatic <code>.ics</code> attachment so the customer adds the appointment to their calendar in one click.</li>
<li>Built-in GDPR compliance — Explicit consent before submission, WP_Privacy exporters/erasers, configurable retention, automatic anonymisation.</li>
<li>Built-in anti-spam — Honeypot and per-IP rate limiting, with no third-party service and no external request.</li>
</ul>
<h4>Who it is for</h4>
<ul>
<li>Freelancers and small businesses who want a self-hosted scheduling page</li>
<li>Agencies packaging a website with a booking funnel</li>
<li>Any business where “book a slot” opens the customer journey</li>
</ul>
<h3>External services</h3>
This plugin is fully self-contained. It makes no calls to any external or third-party service and sends no data off your site — every request is handled on your own WordPress installation.
<h3>Source code and build</h3>
The full, human-readable source code is public and maintained at:
https://github.com/ArchSeraphin/slashbooking-lite
The PHP runs unmodified from <code>src/</code>. The admin interface bundle 
(<code>assets/dist/index.jsx.js</code> and <code>.css</code>) is compiled from the React/SCSS sources 
in <code>src/Admin/react-app/src/</code>, which ship inside the plugin ZIP as well.
To regenerate the compiled admin assets:
<pre><code>npm install
npm run build (uses @wordpress/scripts — webpack/Babel; outputs to assets/dist/)
</code></pre>
The Composer autoloader in <code>vendor/</code> is generated with <code>composer install --no-dev</code>.
