REST client plug-ins are available for most browsers and many IDEs. Many of the examples in the vCloud API Programming Guide for Service Providers were developed using two open-source programs: cURL (http://curl.haxx.se/) and the RESTclient (http://code.google.com/p/rest-client/).

VMware provides additional SDK products that implement language-specific bindings for the vCloud API, and include their own HTTP client capability. See http://communities.vmware.com/community/developer/forums.
