On Asana task completed - Automate.ax

asana.onTaskCompleted fetches the task and emits only when its current completed value is true.

automations/respond-to-asana-completion.automation.ts

import { automation } from "automate.ax"
import { asana } from "automate.ax/asana"

export default automation("Celebrate Asana completion", () => {
  const task = asana.onTaskCompleted({ resourceId: "project-gid" })
  asana.addTaskComment({ taskId: task.id, text: "Nice work!" })
})

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

Trigger data

Returns a Signal<AsanaTaskCompletedEvent> containing the fetched task:

interface AsanaTaskCompletedEvent extends AsanaTask {
  completed: true
  type: "task"
  event: AsanaWebhookEvent<"changed"> & {
    change: {
      action: "changed"
      field: "completed"
      newValue?: true
    }
  }
}

interface AsanaTask {
  id: string
  name?: string
  type?: string
  assignee?: AsanaResource
  assigneeStatus?: string
  completed: boolean
  completedAt?: string
  completedBy?: AsanaResource
  createdAt?: string
  createdBy?: AsanaResource
  customFields: AsanaCustomFieldValue[]
  dueAt?: string
  dueOn?: string
  followers: AsanaResource[]
  htmlNotes?: string
  memberships: {
    project: AsanaResource
    section?: AsanaResource
  }[]
  modifiedAt?: string
  notes?: string
  parent?: AsanaResource
  permalinkUrl?: string
  projects: AsanaResource[]
  subtype?: string
  startAt?: string
  startOn?: string
  tags: AsanaResource[]
  workspace?: AsanaResource
}

AsanaResource and AsanaWebhookEvent have the shared Asana event shapes. Returns the current AsanaTask with completed: true. event contains action: "changed" and change.action: "changed" for the completed field. Reopening a task doesn’t emit this trigger.
