This is something I mentioned long ago, that somebody should find the cheapest and most powerful report writer package and interface to the Asana API. I am not qualified for this. It will be a great opportunity for you programmers. Just as an example their is Zoho Reports that can read Asana API. Don’t even think of using their task manager, I tried it and it was a nightmare for my team. Asana is so much better. The point is I asked them and here is there reply. So go for it. It may not even be Zoho. @Matt_Bramlage are you aware of any Asana users linking a Report Writer to your API?
You can use Asana Export API to import data into Zoho Reports for reporting. Alternatively, you may also use get data from Asana and accumulate in a cloud storage or in FTP server and import data into Zoho Reports for reporting.
