# On attachment deleted

> Runs when Asana permanently deletes an attachment propagated through the watched resource.

`asana.onAttachmentDeleted` watches one Asana resource. Runs when Asana permanently deletes an attachment propagated through the watched resource.

```ts automations/asana-on-attachment-deleted.automation.ts theme={null}
import { automation } from "automate.ax"
import { asana } from "automate.ax/asana"

export default automation("On attachment deleted", () => {
  const change = asana.onAttachmentDeleted({ resourceId: "project-gid" })
  // Remove the deleted Asana attachment from the document index.
})
```

Provide `resourceId`. Optional static `account` defaults to the project binding.

Returns a signal containing the affected attachment reference and the compact normalized webhook event. The event has `resourceType: "attachment"` and `action: "deleted"`; field-specific triggers also narrow `event.change.field` and `event.change.action`. Call the corresponding get action when you need full current resource state.
