REST API and Webhooks for Custom Integrations
Use the REST API to connect mobile-calendar to your own app, accounting system, or reporting tool. Webhooks notify your system about events as they happen.

What it is
The REST API is a public interface for developers and companies building their own integrations with mobile-calendar. It is for properties that want to use the same data in multiple systems, such as a CRM, accounting system, or Business Intelligence tools. Channel Manager provides ready-made connections to booking portals, not the API.
How it works
An external app logs in using API account credentials and can read and write data such as reservations, blocked dates, rooms, clients, the price list, availability, and invoices. The access scope depends on the API account permissions.
Webhooks work in the opposite direction. When something happens, such as a new reservation being created, mobile-calendar automatically sends a notification to your system’s address, so your system does not need to ask the API for updates. Developer logs show the history of API requests. The REST API, webhooks, and logs are available with a Premium subscription.
