Can I trigger a build via API and wait for it to complete?

Hi all -

I have a build step that calls a new build of a different project via the circleCI API. This is working OK, but it issues the PUT and then immediately returns. Is there a way to wait for the dependent build to complete before completing to parent build? Or at least some way to verify that build completed green?

Just inquired about this to Engineering Support. I’ve also written it up here which can probably be marked as a duplicate now!
