Hi @Mikhail, n8n triggers typically receive webhooks from external services like ClickUp without adding any logic on their own. Seeing you receive two different events here (task created and status updated), this simply seems to be the way ClickUp works. You might want to check directly with ClickUp when exactly which webhook is emitted.
Just to follow up from what @MutedJam mentioned I have just taken a look at ClickUps API docs for webhooks and it looks like they send a created and updated webhook on creation of a new item.
taskCreated payload
This webhook is triggered when a new task is created. We also send the taskStatusUpdated payload when a new task is created.
