I need to maintain list if all user's incomplete tasks with asana API.
Right now, the best solution I came up with is polling asana for every X minutes and use /tasks with completed_since filter. However this is inefficient, since I have to perform exactly one call for every workspace.
The next thing I tried was looking into /events API, but events are generated only for projects and tasks. I got about 25 projects so it isn't the best solution either.
Is there any way I could check for updates efficiently?
Thanks.
Actually, "exactly one call per workspace" is as good as it's gonna get - we scope each request to a workspace (in fact, it's likely that in the future each API call will need to be explicitly scoped to a workspace). It's a hard IP boundary, so basically we never "mix" data from different workspaces (except for certain exceptions, like "listing the workspaces I'm in").
If you're specifically only looking for updates to tasks, you could also use modified_since.
