5 Key Features That Make WP Booking Pro Developer-Friendly

As a developer or business owner evaluating booking plugins, you need more than a pretty calendar. You need a system that integrates with your workflow, syncs with your tools, and gives you the flexibility to customize when needed.

WP Booking Pro was built with these needs in mind. Here is a deep dive into the features that set it apart.

Google Calendar Synchronization

One of the most requested features in any booking system is calendar integration. WP Booking Pro offers two-way Google Calendar sync that automatically:

• Creates calendar events when bookings are approved
• Updates events when booking details change
• Removes events when bookings are cancelled or rejected
• Uses OAuth 2.0 for secure authentication (no API keys stored on your server)

The sync is handled through a secure OAuth proxy, meaning your Google credentials are never stored locally. When a customer books an appointment and you approve it, the event appears in your Google Calendar within seconds.

ICS Calendar Attachments

For customers, every confirmation email includes an .ics calendar file they can add to any calendar app – Apple Calendar, Outlook, Google Calendar, or any other standards-compliant client.

Developer Hooks for Custom Integrations

WP Booking Pro follows WordPress best practices with a comprehensive hook system. This means developers can extend functionality without modifying core plugin files.

Available Action Hooks

• wpbp_booking_created – Fires when a new booking is submitted
• wpbp_booking_approved – Fires when a booking is approved
• wpbp_booking_rejected – Fires when a booking is rejected
• wpbp_payment_verified – Fires when a bank transfer payment is confirmed
• wpbp_loyalty_stamp_granted – Fires when a loyalty stamp is recorded
• wpbp_loyalty_reward_earned – Fires when a customer earns their discount

This hook-based architecture means you can integrate WP Booking Pro with virtually any system – CRMs, marketing automation, custom dashboards, or third-party services.

Complete REST API

For developers building custom frontends or integrating with external applications, WP Booking Pro exposes a full REST API under the wpbp/v1 namespace.

Key Endpoints

• GET /wpbp/v1/bookings – List all bookings (admin)
• POST /wpbp/v1/bookings – Create a new booking (public)
• GET /wpbp/v1/availability/{date} – Check available time slots
• GET /wpbp/v1/availability/month/{year}/{month} – Get monthly availability
• POST /wpbp/v1/bookings/{id}/approve – Approve a booking
• GET /wpbp/v1/analytics/dashboard – Retrieve dashboard statistics

All admin endpoints require authentication via WordPress nonces or application passwords. Public endpoints (like availability checks) work without authentication to enable frontend booking widgets.

Payment Integrations

WP Booking Pro supports multiple payment methods out of the box:

• Stripe – Accept credit card payments with PCI-compliant checkout
• PayPal – Let customers pay with their PayPal account
• Bank Transfer – Collect deposit information with manual verification
• Pay Later / On Arrival – For businesses that collect payment in person

Each payment method includes proper status tracking. Bank transfers, for example, set bookings to a pending payment verification state until an admin confirms receipt.

Modern Architecture

Under the hood, WP Booking Pro uses modern technologies:

• React 18 for the booking calendar and admin interface
• TypeScript for type-safe frontend code
• Tailwind CSS for responsive, customizable styling
• WordPress REST API for all data operations
• PSR-4 autoloading for clean PHP architecture

The React-based frontend means smooth interactions without page reloads. The calendar updates in real-time, and the admin dashboard provides instant feedback.
