Automating guest access is no longer optional for modern rental businesses.
In this case study, Bolder Technologies implemented a custom Honoris API integration with Guesty to deliver smart lock automation for rentals using a robust, event-driven PMS API architecture.
This project demonstrates how Guesty custom automation combined with Honoris lock with PMS API can eliminate manual access handling and operational errors at scale.
Project Overview
The client operates serviced apartments and vacation rentals using Guesty as their core PMS and Honoris for secure property access.
Their business required:
- Automated access code creation
- Time-bound lock access per reservation
- Zero manual intervention by staff
- Full synchronization between PMS and lock system
This required a custom Honoris API integration, not an off-the-shelf plugin.
The Operational Problem
Before implementing smart lock automation for rentals, the client faced:
- Manual creation of lock codes for every booking
- Risk of wrong access during late check-ins
- No automatic deactivation after checkout
- No visibility of access details inside the PMS
- Increased guest support requests
These issues scaled badly as the number of reservations increased.
The Expert Solution by Bolder Technologies
At Bolder Technologies, we designed a Guesty custom automation workflow that connects reservations directly with Honoris smart locks using secure APIs and webhooks.
What We Built
1. Guesty Webhook Automation
- Captures
reservation.newandreservation.updatedevents - Processes real-time booking changes
2. Reservation Logic & Validation
- Extracts check-in and check-out dates
- Calculates stay duration automatically
- Maps apartment and lock identifiers
3. Honoris API Integration
- Sends validated access data to Honoris
- Generates time-restricted access codes
- Prevents unauthorized or extended access
4. PMS Sync Back to Guesty
- Updates Guesty custom fields with access information
- Keeps operations teams informed inside the PMS
5. Error Handling & Security
- Webhook logging and retries
- Token lifecycle handling
- Secure credential management
This architecture ensures reliable Honoris lock with PMS API synchronization.
How the Smart Lock Automation Works
End-to-end flow:
- Guesty triggers a reservation webhook
- Booking data is validated
- Stay duration is calculated
- Honoris API receives lock access request
- Access details are generated
- Guesty reservation is updated automatically
All actions happen within seconds — no staff involvement required.
Why This Required a Guesty Automation Expert
This project was not a basic API connection.
Key technical challenges handled:
- Guesty Open API authentication lifecycle
- Secure webhook consumption
- Custom field updates without overwriting PMS data
- Lock-specific access constraints
- Idempotent webhook processing
- Production-grade logging and monitoring
This is why businesses looking for Honoris API integration or Guesty custom automation should hire a specialist, not rely on generic developers.
Business Impact
After implementing the solution, the client achieved:
- Fully automated guest access
- Zero manual lock code handling
- Reduced late check-in issues
- Improved guest experience
- Scalable automation for future properties
The system now supports growth without increasing operational workload.
Who This Solution Is For
