3 Using the OPERA Cloud APIs

When utilizing the OPERA Cloud APIs, you can choose from the following options based on your specific use cases:

• Synchronous APIs — The synchronous property APIs are designed to cater to a specific use case in OPERA Cloud by operating on a request-reply basis and demanding immediate responses. For instance, you can use the getReservation API to fetch detailed reservation data. For detailed implementation guidelines on using the synchronous APIs, see Calling Oracle Hospitality Property APIs.
• Asynchronous APIs — The asynchronous property APIs are designed for revenue management systems, allowing retrieval and updating of bulk data such as inventory, restrictions, and room rates in OPERA Cloud. For detailed implementation guidelines on using the asynchronous APIs, see Using the Asynchronous APIs.
• Business Events — A business event is an event (that is, an update) that happens to a resource, for example, a reservation. For detailed implementation guidelines on using the business events, refer to the Business Events topics.
