Integrate with Workable via StackOne

OVERVIEW

StackOne’s Universal Integration Layer for B2B SaaS providers allows you to integrate your product with not only Workable but also the wider eco-system of ATS & HRIS platforms via a single API connection, on a one-to-many basis.

Build once to StackOne and power deep, real-time, bi-directional, enterprise-grade integrations with Workable and dozens of other leading ATS & HRIS platforms within a single engineering sprint.

BENEFITS OF USING STACKONE VS. NATIVE WORKABLE INTEGRATION

  • Pre-built integrations and components to allow you to rapidly build native integrations, fast.
  • Deep, pre-mapped unification for specific use cases (eg. Background Checking, Candidate Assessment, Employee & Group sync etc)
  • Accelerate time‑to‑market: production‑ready Workable integration in days, not weeks.
  • Future‑proof maintenance: StackOne monitors API changes and auto‑patches connectors.
  • Enterprise‑grade security: SOC 2 Type II, HIPAA, GDPR, zero‑data‑storage, multi-region data processing.
  • Real‑time platform —no batch sync delays, no PII data storage.
  • AI Agent ready interfaces; enable your AI Agent to take autonomous, real-time read/write actions across Workable and your customers’ wider HR tech stack.

KEY PLATFORM FEATURES

  • Unified HRIS data model – employees, groups, time-off, compensation, locations, work eligibility, custom fields and more.
  • Bi‑directional, real‑time integrations and sophisticated webhook architecture.
  • Embedded Integration Hub – drop‑in, white‑label UI for end‑user authorisation.
  • Pre-written connection guides for hundreds of integrations
  • Tool calling interfaces for AI Agents
