What is a Webhook?

Updated 2026-05-28

A webhook is an automated communication method that allows one application to send real-time data to another when a specific event happens. Unlike a traditional API that requires one system to periodically request data from another, a webhook automatically 'pushes' information as soon as the event is triggered.

This event-driven approach makes webhooks an efficient way for different software systems to communicate instantly. For example, a confirmed booking can trigger a webhook that immediately notifies a host's property management system.

How it works

A webhook operates by registering a URL from a receiving application (the 'listener') with a source application. When a predefined event occurs in the source—such as a new booking, a cancellation, or a completed payment—it sends an HTTP POST request containing a data payload (typically in JSON format) to the registered URL.

The receiving application then processes this data to trigger a corresponding action. This could include blocking dates on a calendar, sending a confirmation email, or generating a smart lock code, all occurring in real time without manual intervention.

Why it matters

Webhooks are crucial for creating seamless, automated workflows in vacation rental management. They enable real-time synchronization between disparate systems, like a channel manager, a dynamic pricing tool, and smart home devices.

This automation reduces manual data entry, minimizes the risk of errors like double bookings, and enhances the guest experience by triggering timely actions. Platforms like Lodgify can utilize webhooks to connect with external services for tasks like automated guest messaging or smart lock management, streamlining hosting operations.

Examples

  • A guest makes a new booking on Vrbo. Vrbo sends a webhook to the host's PMS, which automatically updates the property's calendar and sends a welcome email to the guest.
  • A dynamic pricing tool detects a surge in local demand. It sends a webhook to the host's channel manager, which instantly updates the nightly rates across all connected OTAs and the direct booking website.
  • A guest completes their pre-arrival online check-in form. A webhook is sent to a smart lock management system, which generates a unique access code scheduled to be active for their stay.
  • After a guest checks out, a cleaning management app receives a webhook from the PMS. The app automatically assigns the turnover task to an available cleaner and notifies them of the new job.

Frequently asked questions

What is the difference between a webhook and an API?+
The main difference is how they initiate communication. With a standard API, a client application must periodically 'poll' or request data from a server. With a webhook, the server automatically 'pushes' data to the client application as soon as a specific event occurs, making it more efficient for real-time updates.
Are webhooks secure?+
Webhooks can be secured using several methods. Common practices include using HTTPS for the webhook URL to encrypt data in transit and including a secret key or signature in the webhook header. The receiving application can then verify this signature to ensure the request is from a legitimate source.
Do I need to be a developer to use webhooks in my vacation rental business?+
While developers build the underlying infrastructure, many modern software tools offer user-friendly interfaces for webhook integrations. Services like Zapier or Make allow non-technical users to connect different apps using webhooks through a simple 'if this, then that' graphical interface, without writing code.
What are some common uses for webhooks in property management?+
Common uses include syncing calendars after a new booking, automating guest messages, generating smart lock codes, updating rates from a dynamic pricing tool, notifying cleaners of a check-out, and adding guest contact information to a CRM system.
