What is a 

Unified ATS API

Every applicant tracking system - Greenhouse, Lever, Ashby - stores candidate and hiring data differently, with its own authentication methods, schemas, and APIs. Building separate integrations for each takes months of engineering work and ongoing maintenance as APIs evolve.

A Unified ATS API standardizes these differences into a single interface. Integrate with Knit once to access multiple ATS platforms through one unified data model.

Your team works with a single API while Knit handles translation, rate limiting, retries, and sync management behind the scenes.
