You used to allow for ID, but then apparently started recommending GID. I get that. The Zapier integration still allowed for ID and GID.
You can see here that ID and GID were both returned by your own API too (up until when, I’m not sure): Can`t create task with API
You can also read more about it here: Asana is moving to string IDs [Updated with revised timeline]
- But note, based on that thread, I don’t see anything saying that the
idoutput will actually cease to exist — especially not that it would have worked up until Monday with Zapier.
