Announcing a beta release (version 0.5.5.5) of a plugin for TeamCity which enhances TeamCity to provide WebHook functionality. With the tcWebHooks plugin installed, you can tell TeamCity to trigger a webhook POST request as build events occur.
WebHooks are configured on a project basis, and when events occur in the build process, a POST request is submitted to the URL. You can configure as many URLs as you like (within reason) and which events will trigger the request.
There is support for proxies in this version, and webhooks are configured in the TeamCity UI. There are a few outstanding items to tidy up, but the core functionality is working.
The project is on SourceForge at tcplugins.sourceforge.net.
