CASY API is a RESTful API for authorized users, mainly providing access to hotel bookings, guest information, and property management data. Its base URL is https://onlinebuchungen.ch/v1, the current version is /v1, and responses are in application/json. Based on the documentation notes, this is not an open public service: all usage is monitored and logged, and unauthorized access will be investigated.
In terms of functionality and use cases, CASY API focuses on hotel and property management scenarios. It can be used for booking data synchronization, guest profile lookup, account-scoped filtered access, and internal system integration. Authentication uses the common Bearer Token method, requiring Authorization: Bearer your-token-here in the request header. Tokens must be requested by contacting [email protected]. Permissions can be configured per customer, such as access to specific hotels or all hotels, account data access, companion guest data access, and administrator privileges.
The default rate limit is 10 requests per 60 seconds. Exceeding this limit returns HTTP 429 along with fields such as error, window_seconds, and limit. Custom rate limits can be configured per Token upon request. The documentation structure includes Overview, Endpoints, Data Format, Error Codes, and Changelog, and also provides a Quick Start flow, so the basic development path appears fairly clear. However, the captured content does not show a complete endpoint list, field schemas, request/response examples, or code snippets, nor does it mention an official SDK. As a result, it is still difficult to judge developer efficiency and suitability for complex integrations.
The text does not provide pricing, payment methods, open-source status, or self-hosting options. Given the “authorized users only” positioning and the need to request a Token by email, it appears to be more of a closed business API for existing customers or partners rather than an open platform for public developers. In terms of integration ecosystem, the documentation only shows the permission model and API entry point; it does not list third-party plugins, Webhooks, SDKs, or a marketplace ecosystem.
Its strengths are standard protocols, a clearly defined data domain, relatively granular permissions, and basic documentation for rate limiting and error handling. The drawbacks are limited public information, a low default rate limit, and the lack of pricing, SLA details, SDKs, complete examples, and a self-service onboarding process. It is better suited to enterprise customers already using CASY or related hotel management systems, system integrators, and internal development teams. It is not well suited as a general developer API for open evaluation or quick trial use.
The captured text does not provide information about access from mainland China, network nodes, or payment options. It is not possible to confirm whether the domain and API endpoint can be accessed directly, so this is currently unknown. For teams in China, it is recommended to first test API connectivity, latency, and email support response times. If access is unstable, consider using an enterprise network, compliant proxy, or a local hotel PMS/API solution as an alternative.
