Can you provide some more detail as to what you mean by “task progress info”? There isn’t a specific Asana data item by that name, so I’m just wanting to be able to map your request to the Asana data objects that would correspond to it so we can give you a good answer.
@lpb is right, this is exactly what I want. I’m current manually calculating it using num_completed_tasks/num_tasks that I get using task_count method.
Got it (and thanks @lpb). There’s no way to get that data for multiple projects with one API call. The best you can do is to batch multiple requests using the Batch API - you’re still doing one request per project, but you can do a batch of them simultaneously.
