thanks @Arthur_BEGOU for this, I have setup nearly exactly what you did, so looks to be a good appraoch . You talk about app integrations, but is there any other way of giving external (not Asana users) clients visibility on their tasks, at least status? Assume you have tickets from 5 customers in your project and you like each client to only see obviously their tickets, and from these only some specific fields like title, date opened, status and a comment. Ideally one could sent a specific link to each customer so they can access their tickets via browser view. I have absolutely no clue how to tackle this, but maybe somebody is already further in these thoughts…?
=> You can decide to invite externals at the task level only (not at the project level); this way, they’ll see only the task they are allowed to see
I’ve just created a forum tips to review the process of inviting guests in tasks
=> This part is different, I’m investigating at the moment.
