Developing a Web Services Client 2
VMware vRealize Orchestrator provides Web services APIs so that you can develop applications to access
workows through the Web. The main purpose of the Orchestrator Web services APIs is to allow you to
integrate Orchestrator workows in custom Web-based applications.
Orchestrator provides a Web services API that is based on a representational state transfer (REST) API. The
Orchestrator REST API exposes the objects in the Orchestrator inventory and the inventories of the installed
plug-ins as resources that you can access at predened URLs. HTTP requests at these URLs result in
triggering operations over workows. The Orchestrator REST API exposes inventory objects as resources
through a set of RESTful Web services that you can use to retrieve the denitions of workows, run
workows, check the status of the running workows, cancel workow runs, process waiting user
interactions, retrieve the presentation of workows, and so on.
