Triggering a build using webhooks or similar

I’d quite like to trigger a build using an HTTP post, as we currently still do with FinalBuilder Server, rather than have Continua constantly polling our Kiln server for changes. Is that possible, and if so, can I have a link to the documentation?

Ah never mind, I see it now. When selecting “Manual” you get a URL you can use to trigger the build. I assumed manual meant it never triggered unless you clicked a button somewhere in ContinuaCI to manually request a build.
