Overview

Subscribe to webhook events to receive instant notifications when timers are stopped in your workspace. This endpoint enables Zapier’s “Timer Stopped” trigger integration, automatically forwarding completed time entry data to your connected workflows.
This endpoint is primarily designed for Zapier integrations but can be used with any webhook service that follows the same pattern.

Zapier Integration Guide

​
Setting Up the Trigger

  1. Automatic Setup: Zapier automatically calls this endpoint when you configure a “Timer Stopped” trigger
  2. Event Subscription: The integration subscribes to TIMER_STOPPED events
  3. Data Flow: Timer stop data is instantly sent to your Zap workflow
Zapier automatically provides the webhook URL via bundle.targetUrl when setting up the trigger. You don’t need to manually generate URLs.

​
Important Notes

Workspace Scope: Webhook subscriptions are tied to your specific API key and workspace. Ensure you’re using the correct credentials for your intended workspace.
Data Format: The webhook payload structure matches the standard time entry data format used across all time tracking API endpoints, ensuring consistency in your integrations.
Best Practices:
  • Validate webhook signatures if implementing custom security
  • Implement proper error handling for webhook delivery failures
  • Use HTTPS endpoints only for security
  • Test your webhook endpoint before subscribing
