Webhooks

A mechanism that allows one system to automatically send real-time data to another system when a specific event occurs.

Definition

A webhook delivers event-based notifications through HTTP callbacks, transmitting relevant data as soon as actions such as a candidate application submission, interview scheduling update, background check completion, or onboarding form submission take place. Unlike traditional API polling, where one system repeatedly checks another for updates, webhooks push data instantly when something happens, making them faster and more efficient.

Webhook implementation is built around:

  • Secure endpoint configuration with authentication and verification
  • Event subscription management to control which HR events trigger notifications
  • Payload validation to confirm data integrity and structure
  • Encryption of data in transit using HTTPS
  • Logging and monitoring of webhook activity for troubleshooting and auditing
  • Retry logic to handle failed deliveries and ensure data consistency

Webhooks are a foundational component of modern HR technology integrations. When a candidate submits an application through an applicant tracking system, a webhook can instantly notify a background check provider, update a CRM, or trigger an onboarding workflow without any manual intervention or delay.

Why It Matters

In a connected HR technology ecosystem, data needs to move between systems in real time. Webhooks make this possible without the overhead and latency of continuous API polling. For organizations managing high volumes of applicants, even small delays in data synchronization can lead to missed communications, duplicate entries, or compliance gaps.

For HR technology providers building on platforms like HiringThing, webhooks are essential for creating seamless integrations. They allow partner systems to react immediately to hiring events, keeping candidate records synchronized across applicant tracking, payroll, HRIS, and onboarding platforms. This real-time data flow reduces manual data entry, prevents errors, and creates a smoother experience for both recruiters and candidates.

HiringThing’s developer platform and open API include webhook support, enabling partners to subscribe to key events and receive instant notifications as candidates move through the hiring pipeline. This makes it straightforward to build tightly integrated recruiting solutions that keep every connected system up to date.
