What is Bookingistic?

Bookingistic turns a WordPress site into a premium booking system — for strategy calls, salons, clinics, tutors, fitness trainers, consultants, home services and any appointment-based business. It is built by WordPressistic ("Build Your Business Automation with AI") and is part of the WPistic suite alongside Bridgistic, the safe AI-control bridge for WordPress.

Everything in this repository is free and open source — no feature gates, no license keys, no in-plugin upsell.

Requirements

• WordPress 6.4+, PHP 8.0+
• Optional: Elementor for the drag-and-drop widget
• Optional: a free Google OAuth client for two-way calendar sync (setup guide lives in Bookingistic → Integrations)
• Optional: WooCommerce for paid bookings

Installation

From WordPress.org — Plugins → Add New → search "Bookingistic" → Install → Activate.

From a release zip — download bookingistic-<version>.zip from Releases, then Plugins → Add New → Upload Plugin.

From source —

git clone https://github.com/Wordpressistic/bookingistic.git
cp -r bookingistic /path/to/wp-content/plugins/

Getting started

1. Activate the plugin, then open Bookingistic → Appearance and pick an industry preset (Salon, Clinic, Fitness, Tutoring, Consulting, Home Services) — or design your own look with the accent color and corner-radius controls.

2. Add your bookable services under Bookingistic → Services (duration, buffers, price, deposit, auto/manual confirmation).

3. Add staff under Bookingistic → Staff — per-day working hours, days off, holidays, daily booking limits, and (optionally) each member's Google Calendar.

4. Place the form on any page:

   [bookingistic service="strategy-call"]
   [bookingistic service_id="1" template="split" calendar_view="pills"]

   — or drag in the Bookingistic Form widget in Elementor.

5. Paid services: enable WooCommerce Orders under Bookingistic → Payments. Customers pay with any method your store already supports and payment status flows back to the booking automatically.

6. Optional: connect Google Calendar per staff member under Bookingistic → Integrations for two-way sync — confirmed bookings push out, external events block slots, refreshed every 15 minutes.

Customers book without an account; cancel and reschedule work through signed, expiring links in their emails.

REST API

GET  /wp-json/bookingistic/v1/services
GET  /wp-json/bookingistic/v1/availability?service_id=N&date=YYYY-MM-DD
POST /wp-json/bookingistic/v1/bookings
POST /wp-json/bookingistic/v1/bookings/{id}/reschedule
GET  /wp-json/bookingistic/v1/payments
GET  /wp-json/bookingistic/v1/payments/gateways

The public bookings endpoint is honeypot- and rate-limit-protected; staff email addresses are never exposed. Backward compatibility with the v1 wpistic_booking CPT and the legacy POST /wpistic/v1/bookingistic/request route is maintained.

For developers

// Filter available slots before render
add_filter( 'bookingistic_available_slots', fn( $slots, $service, $date, $staff_id ) => $slots, 10, 4 );

// Inject external busy intervals (the Google freebusy integration uses this)
add_filter( 'bookingistic_external_busy_intervals', fn( $intervals, $staff_id ) => $intervals, 10, 2 );

// React to the booking lifecycle
add_action( 'bookingistic_booking_confirmed', function ( $booking, $customer, $service ) { /* ... */ }, 10, 3 );

// Add a payment gateway (implements Bookingistic\Payments\Payment_Gateway)
add_filter( 'bookingistic_payment_gateways', function ( array $gateways ) {
    $gateways['my_gateway'] = new My_Gateway();
    return $gateways;
} );

// White-label: remove the email footer credit (free for everyone since 2.5.1)
add_filter( 'bookingistic_can_remove_branding', fn() => true );

Architecture notes: namespaced OOP under Bookingistic\ with PSR-4-style autoloading from includes/, dedicated custom tables (services, staff, customers, bookings, payment records, email automations, email logs, calendar events), and an opt-in data wipe on uninstall via BOOKINGISTIC_DELETE_DATA.

External services & privacy

The plugin makes no external CDN calls and ships no telemetry.

The only optional external integration is Google Calendar, and only after a staff member explicitly connects their own free OAuth client from the staff editor:

• Used for: pushing confirmed bookings to the connected calendar and reading its free/busy blocks so external events block booking slots.
• Data sent, and when: booking details (service name, date/time, customer name and notes) when a connected staff member's booking is confirmed, rescheduled or deleted.
• Endpoints: accounts.google.com, oauth2.googleapis.com, www.googleapis.com.
• Google Terms of Service · Google Privacy Policy

Bookings, customers and email logs are stored in the site's own database. OAuth tokens are encrypted at rest; calendar (.ics) email attachments are written to the system temp directory and deleted after sending.
