Hey everyone, thank you for your feedback and patience on this topic! While we generally strive to build APIs as fast-follows to new features features in the Asana web product, it’s not always possible to do so.
The good news is that a tasks template API is currently being built. We don’t have a release date yet, but we hope to have the work finished in a few months. We will post an update on this thread when we have more details to share.
