Get notified when Tasks complete with webhooks
Starting today, webhooks are available for all Task Runs on the Parallel Task API[Parallel Task API]($https://parallel.ai/blog/parallel-task-api) - including Deep Research[Deep Research]($https://parallel.ai/blog/introducing-parallel). Get notified when your tasks complete instead of continuously checking their status.
When you're orchestrating hundreds or thousands of web research tasks, webhooks push real-time notifications to your endpoint as tasks complete - eliminating the need for constant polling. This is especially valuable for long-running or research-intensive tasks.
Common use cases include:
With webhooks - your orchestration code stays clean, error handling becomes straightforward, and results naturally flow into your existing queue-based architectures.
Setting up webhooks requires minimal changes to your existing integration. Simply include a webhook configuration alongside your task specification:
When your task completes, we POST the full result to your endpoint.
For security, webhooks follow standard conventions[standard conventions]($https://github.com/standard-webhooks/standard-webhooks/blob/main/spec/standard-webhooks.md) including signature verification. You can manage your webhook secret keys in Settings->Webhooks[Settings->Webhooks]($https://platform.parallel.ai/settings?tab=webhook) on our Developer Platform.
Webhooks are available today for all Task API processors. Get started with our documentation[documentation]($https://docs.parallel.ai/task-api/features/webhooks).
