Paycor offers a comprehensive suite of human capital management (HCM) solutions that support various HR and recruiting processes, and integrating with its API can enhance workflow efficiencies. The Paycor API allows access to employee and candidate data, supporting both internal integrations within a business and customer-facing applications. Key functionalities include fetching employee records and payroll data, with a rate limit of 1,000 calls per minute and various error codes for request handling. Authentication requires either an access token or an API key, which involves a multi-step process through Paycor’s Developer Portal. Integrations can automate processes such as payroll reconciliation, secure document storage, and new hire provisioning, and they can be powered by AI agents for data analysis. Best practices include using sandbox accounts for testing, matching redirect URIs, and implementing retry logic for handling rate limits. Additionally, the Merge platform facilitates integrating Paycor with over 70 other HRISs through its Unified HRIS API, providing tools for data synchronization, issue management, and customer support to streamline integrations at scale.
