ClickUp Webhooks & Events

Overview

ClickUp webhooks send HTTP POST notifications when resources change. Register webhooks via API, subscribe to specific events, and receive payloads with history_items showing what changed.

Webhook Endpoints

POST   /api/v2/team/{team_id}/webhook    Create webhook
GET    /api/v2/team/{team_id}/webhook    Get webhooks
PUT    /api/v2/webhook/{webhook_id}      Update webhook
DELETE /api/v2/webhook/{webhook_id}      Delete webhook

Create a Webhook

async function createWebhook(teamId: string, endpoint: string, events: string[]) {
  return clickupRequest(`/team/${teamId}/webhook`, {
    method: 'POST',
    body: JSON.stringify({
      endpoint,        // Your HTTPS URL
      events,          // Array of event names
      space_id: null,  // Optional: limit to specific space
      folder_id: null, // Optional: limit to specific folder
      list_id: null,   // Optional: limit to specific list
      task_id: null,   // Optional: limit to specific task
    }),
  });
}

// Subscribe to task and list events
const webhook = await createWebhook('1234567', 'https://myapp.com/webhooks/clickup', [
  'taskCreated',
  'taskUpdated',
  'taskDeleted',
  'taskStatusUpdated',
  'taskAssigneeUpdated',
  'taskDueDateUpdated',
  'taskCommentPosted',
  'taskTimeTrackedUpdated',
  'listCreated',
  'listUpdated',
  'listDeleted',
]);

// Response:
// { "id": "wh_abc123", "webhook": { "id": "...", "endpoint": "...", "events": [...] } }

    }
  ]
}

Webhook Handler (Express)

import express from 'express';

const app = express();
app.use(express.json());

app.post('/webhooks/clickup', async (req, res) => {
  const { event, webhook_id, task_id, history_items } = req.body;

  // Immediately acknowledge (ClickUp expects 200 within 30s)
  res.status(200).json({ received: true });

  // Process asynchronously
  try {
    await processClickUpEvent(event, task_id, history_items);
  } catch (err) {
    console.error(`Failed to process ${event} for task ${task_id}:`, err);
  }
});

async function processClickUpEvent(
  event: string,
  taskId: string,
  historyItems: any[]
) {
  switch (event) {
    case 'taskCreated':
      console.log(`New task: ${taskId}`);
      break;
    case 'taskStatusUpdated': {
      const change = historyItems[0];
      console.log(`Task ${taskId}: ${change.before.status} -> ${change.after.status}`);
      // Trigger downstream actions (e.g., notify Slack, update external system)
      break;
    }
    case 'taskCommentPosted':
      console.log(`New comment on task ${taskId}`);
      break;
    case 'taskTimeTrackedUpdated':
      console.log(`Time tracked updated on task ${taskId}`);
      break;
    default:
      console.log(`Unhandled event: ${event}`);
  }
}

Idempotency (Prevent Duplicate Processing)

const processedEvents = new Map<string, number>();

function isDuplicate(webhookId: string, historyItemId: string): boolean {
  const key = `${webhookId}:${historyItemId}`;
  if (processedEvents.has(key)) return true;
  processedEvents.set(key, Date.now());

  // Clean old entries every 1000 events
  if (processedEvents.size > 10000) {
    const cutoff = Date.now() - 3600000; // 1 hour
    for (const [k, v] of processedEvents) {
      if (v < cutoff) processedEvents.delete(k);
    }
  }
  return false;
}

List and Manage Webhooks

# List all webhooks for a workspace
TEAM_ID="1234567"
curl -s "https://api.clickup.com/api/v2/team/${TEAM_ID}/webhook" \
  -H "Authorization: $CLICKUP_API_TOKEN" | jq '.webhooks[] | {id, endpoint, events}'

# Delete a webhook
curl -s -X DELETE "https://api.clickup.com/api/v2/webhook/WH_ID" \
  -H "Authorization: $CLICKUP_API_TOKEN"

Error Handling

Issue	Cause	Solution
Webhook not firing	Endpoint not HTTPS	Webhooks require HTTPS URLs
Duplicate events	No idempotency	Track history_item IDs
Timeout (no 200)	Slow processing	Respond 200 immediately, process async
Webhook auto-disabled	Repeated failures	ClickUp disables after many 5xx responses
