As I said. It will be great to have an ID field that increments each time a task is created.
Hi @JavierHSAP each project, tasks (or conversation has an ID in Asana (see screenshot below). With that said the community is strongly advocating for shorter and easier IDs, if you haven’t yet, I would recommend to add your vote on this existing thread we have in the Forum: Short task link with ID
Hope this helps!
