About this plugin
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.
Main features
- Public booking form via shortcode — A single [slashbooking] in any page. Multiple services, date picker, real-time slots, customer form, fully responsive.
- 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.
- Smart buffers around appointments — Configure padding (travel, prep) between appointments. Applied automatically.
- Multi-slot opening hours — Monday 9–12 + 14–18, Tuesday morning only, Wednesday off… Each day and each service is configured independently.
- Transactional emails with.ics — Confirmation, decline and acknowledgement emails, each with an automatic.ics attachment so the customer adds the appointment to their calendar in one click.
- Built-in GDPR compliance — Explicit consent before submission, WP_Privacy exporters/erasers, configurable retention, automatic anonymisation.
- Built-in anti-spam — Honeypot and per-IP rate limiting, with no third-party service and no external request.

External services
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.
