 REST services provided by Mendix Apps running in Mendix Cloud (published [OData](/refguide/published-odata-services/) and OpenAPI REST Services), Web Services, and Business Events are automatically registered in your organization's Catalog upon deployment. This provides you with an up-to-date view of all the OData, OpenAPI, Web Service and Business Event endpoints published and consumed by your Mendix apps. These assets can be [curated](/catalog/manage/curate/) in the Catalog to ensure that they are exposed to the relevant users and can be found easily.
