How do I get subtasks using opt_fields using the Asana API?

Question

I'm able to get tons of information through a single query using the Asana RESTful API:

https://app.asana.com/api/1.0/projects/10310306241538/tasks?opt_fields=notes,completed_at,projects,tags,tags.name&opt_pretty

But I can't seem to get subtasks using this query. Is it possible? I'm looking for subtask names, completion, and completion date, if possible.

Thanks!

Currently this is not possible, but it's something we're looking to make possible in future. It's not directly on the roadmap yet so I can't give an estimate of when it'll be available I'm afraid. In the meantime you'll have to make an additional request.
