@Dima5 Hi, can you please provide me with details of your setup? Is it possible that you filter only for removal, not deletion (delete). Remove is the removal of a task of a project, if I’m correct.
Did you include both remove and delete in your filter? I think one of those should report on deletions but I can’t offhand recall which (you’d think it would be delete).
I tried both, but neither works for me, in both cases the webhook is created and is active, but the notification when the task is deleted never arrives, and neither success nor fail appears in the webhook data.
I tested this and did not get a removed or deleted event, either, when I deleted a task. Looks like a bug; I would recommend sending an email to api-support at asana dot com and reporting it!
