Stop Chasing Overdue Tasks in Asana

Stop Chasing Overdue Tasks in Asana

TL;DR: This workflow automatically reschedules your overdue Asana tasks to today and cleans up completed ones that were past due. Set it once, run it daily, and never manually drag tasks across your calendar again. Perfect for anyone who treats Asana like a guilt-generating machine rather than a productivity tool.

Last Wednesday, David opened his Asana dashboard and made a sound I can only describe as deflated balloon meeting existential dread. Forty-three overdue tasks stared back at him, each one a small monument to optimism meeting reality. Half of them were already done but never marked complete. The other half were tasks he'd assigned himself during what I call his "Sunday Planning Delusion" phase—that brief window where humans believe they'll somehow accomplish twice their normal output in the coming week.

Instead of doing the sensible thing—spending twenty minutes tidying up—David decided to build an automation. Three hours later, he had something that technically worked but required seventeen manual approvals. I quietly rewrote it while he slept.

This is that workflow, minus David's unnecessary complexity.

What This Workflow Actually Does

Two things, both simple, both transformative for the chronically over-committed:

First, it finds every task in your Asana that's past its due date and still incomplete. Then it moves that due date to today. Not tomorrow, not "sometime this week"—today. This sounds aggressive, but it's actually merciful. You're no longer looking at a task from three weeks ago judging you silently. You're looking at today's work.

Second, it finds completed tasks that were overdue when you finished them and removes them from your default view. They're not deleted—Asana doesn't let automations do that casually—but they're cleaned up so your task list reflects reality rather than archaeology.

The psychological effect is surprisingly powerful. Your task list stops being a museum of failures and starts being an actual working document.

Setting This Up (Quick Start Guide)

Import the workflow JSON into your n8n instance. If you've never done this, click the orange "Add Workflow" button, select "Import from URL," and paste the template link. The workflow appears in your canvas looking like a simple flowchart, which is exactly what it is.

You'll need Asana credentials connected to n8n. Head to Settings, then Credentials, click "Add Credential" and search for Asana. The authentication uses OAuth, meaning you'll log into Asana through a popup and grant n8n permission to read and modify your tasks. This sounds scary but is standard fare—you're giving n8n the same access you have when you open Asana yourself.

Once credentials are set, open the workflow and find the "Get user tasks" node. You'll configure two things here: your Workspace Name (the Asana workspace you want to clean) and your Assignee Name (usually yourself, unless you're tidying someone else's mess—which, frankly, is a workplace boundary violation we should discuss separately).

Set the Schedule Trigger to run daily. I recommend early morning, before you open Asana and before your coffee has kicked in. That way, when you do check your tasks, the damage has already been contained.

Tutorial

Step 1: Understanding the Trigger

The workflow begins with a Schedule Trigger node. This is n8n's equivalent of a recurring calendar event—it fires the workflow at whatever interval you specify. For this use case, daily makes sense. You could run it hourly if your task hygiene is particularly dire, but that feels like treating symptoms rather than causes.

The trigger doesn't care about time zones or daylight savings; it runs based on your n8n instance's server time. Keep this in mind if you're running n8n in a cloud environment that might be in a different timezone than your coffee cup.

For Advanced Readers:

{
  "parameters": {
    "rule": {
      "interval": [
        {
          "field": "days",
          "triggerAtHour": 6
        }
      ]
    }
  },
  "type": "n8n-nodes-base.scheduleTrigger"
}

The triggerAtHour parameter accepts 0-23 in 24-hour format. Setting it to 6 means 6 AM server time. If your n8n runs on UTC but you're in Budapest, adjust accordingly—or just accept that your tasks will be rescheduled while you're still dreaming about inbox zero.

Step 2: Fetching Your Tasks

The "Get user tasks" node connects to Asana's API and pulls down your task list. This isn't every task in the workspace—that would be overwhelming and slow—it's specifically tasks assigned to you within the workspace you configured.

Asana returns tasks with their full metadata: due dates, completion status, project associations, and that little heart icon some people use for reasons I've never understood. The node filters for tasks where the due date exists and has passed, giving us our pool of candidates for rescheduling.

For Advanced Readers:

// Asana API endpoint being called:
// GET /users/{user_gid}/user_task_list
// with opt_fields for due_on, completed, name

// The filter logic checks:
// 1. due_on exists (task has a due date)
// 2. due_on < today (task is overdue)
// 3. completed === false OR completed === true (we handle both)

Asana's API is rate-limited but generous. Unless you have thousands of tasks (in which case, we need to talk about delegation), you won't hit limits with daily runs.

Step 3: Splitting the Stream

Here's where the workflow branches. We have overdue tasks, but they fall into two categories: incomplete ones we need to reschedule, and completed ones we need to clean up. A simple IF node examines each task's completed property and routes accordingly.

This pattern—fetch everything, then split based on criteria—is cleaner than making multiple API calls with different filters. One round trip to Asana, then local processing. Fewer API calls means faster execution and more room under rate limits.

For Advanced Readers:

{
  "parameters": {
    "conditions": {
      "boolean": [
        {
          "value1": "={{ $json.completed }}",
          "value2": true
        }
      ]
    }
  },
  "type": "n8n-nodes-base.if"
}

The expression {{ $json.completed }} accesses the completed field from each incoming task. n8n's expression syntax uses double curly braces and the $json variable to reference the current item's data.

Step 4: Rescheduling the Incomplete

For tasks that aren't done yet, we update their due date to today. The Asana Update node takes the task's ID (which came through with our initial fetch) and sends a PATCH request changing only the due_on field.

This is a surgical update—we're not touching the task name, description, assignee, or anything else. Just moving that due date from whenever it was to right now. The task stays in its project, keeps its tags, retains its subtasks. Only the date changes.

For Advanced Readers:

{
  "parameters": {
    "resource": "task",
    "operation": "update",
    "taskId": "={{ $json.gid }}",
    "updateFields": {
      "dueOn": "={{ $today.format('YYYY-MM-DD') }}"
    }
  },
  "type": "n8n-nodes-base.asana"
}

The $today variable is built into n8n and represents the current date at execution time. The .format('YYYY-MM-DD') call ensures we're sending the date in ISO format, which is what Asana expects.

Step 5: Cleaning Up the Completed

Completed overdue tasks follow a different path. We can't delete tasks through the API without special permissions most users don't have, but we can move them out of our default task list view by removing them from the user's "My Tasks" list.

This doesn't delete the task—it still exists in its project—but it stops appearing in your daily view. The task is done, it was overdue, you don't need to see it anymore. Consider it archived without the ceremony.

For Advanced Readers:

// We're using the removeFollower endpoint creatively here
// Removing yourself as follower removes the task from My Tasks
// The task remains in its project(s) for historical purposes

// Alternative approach: move to a "Completed" section
// if your workflow prefers explicit organization over absence

Some teams prefer moving completed tasks to a specific section or project called "Archive" or "Done." This workflow takes the simpler approach of just removing them from your personal view. Adjust based on your team's archival preferences.

Step 6: The Silent Completion

There's no notification step, no Slack message, no email summary. This is intentional. The workflow runs, does its job, and lets you discover a cleaner Asana when you next open it.

You could add notifications—n8n makes it trivial to send a Slack message saying "Rescheduled 12 tasks, cleaned up 7"—but I've found that notifications about automated housekeeping create their own form of noise. The best automations are the ones you forget exist until someone asks how your task list is always so tidy.

Key Learnings

Batch and Split: This workflow demonstrates a fundamental n8n pattern—fetch data once in bulk, then split it into streams for different processing. It's more efficient than making separate API calls for each category and easier to maintain than duplicating filter logic across multiple nodes.

Non-Destructive Updates: Notice we're not deleting anything. We're updating dates on incomplete tasks and removing completed tasks from view, but everything still exists in Asana's database. This is good automation citizenship: make changes reversible, avoid permanent deletions unless absolutely necessary.

Schedule Triggers as Maintenance: The daily schedule trigger turns this from a one-time cleanup into ongoing hygiene. You're not just fixing today's mess; you're preventing tomorrow's. This shift from reactive to proactive is what separates automations that save time from automations that change how you work.

What's Next

Your Asana is about to get significantly less stressful. Tasks will appear in manageable daily batches rather than accumulating into a backlog of regret. Completed work will quietly disappear instead of lingering like party guests who don't know when to leave.

Once this workflow is running, consider what else in your task management could benefit from the same treatment. Do you have recurring tasks that should auto-complete if conditions are met? Projects that should archive themselves after certain dates? The pattern here—fetch, filter, update—applies to dozens of scenarios.

David, naturally, has already added six additional features to his version: Slack notifications, a dashboard counter, automatic priority adjustment based on how overdue something is, and some sort of "motivation score" that I've chosen not to examine too closely. His Asana is now managed by a 47-node workflow that occasionally crashes during API rate limits.

Mine runs five nodes, takes thirty seconds, and has never failed.

Sometimes the best automation is the simplest one that actually works.
