Patent number: 11586697Abstract: System and methods for automatically publishing Representational State Transfer (REST) Application Programming Interface (API) changes in a cloud environment are described. A publish/subscribe server (PSS) may receive from a subscriber a customized request for monitoring a registered REST API supported by a REST service provider (RSP) and registered with the PSS. The subscriber is configured to invoke the registered REST API at the RSP. The PSS may monitor the registered REST API for any changes at the RSP based on the customized request. In response to a determination that the registered REST API is changed at the RSP, the PSS may generate a REST API change report indicating a change event occurred to the registered REST API at the RSP after being registered with the PSS. The PSS may then transmit the REST API change report to the subscriber. The subscriber is configured to not invoke the registered REST API at the RSP based on the REST API change report.Type: GrantFiled: February 25, 2019Date of Patent: February 21, 2023Assignee: VMWARE, INC.Inventors: Shuying Yan, Qiang Wan, Changhui Tan, Ming Liu
