How to Register a Workday Developer App and Get OAUTH2 Credentials

To integrate an application with Workday's HRIS, developers need to register a new API client within the Workday tenant by searching for 'Register API Client for Integration' and filling required fields such as Client Name and permission scopes. They must note the Client ID and Client Secret and manage refresh tokens for integration through the 'Manage Refresh Tokens for Integrations' option, ensuring the Integration System User (ISU) has appropriate access. As Workday APIs can be complex, using Unified.to APIs is recommended for simplifying integrations, as it provides a unified set of APIs, data models, and webhooks for HRIS and ATS integrations. Activating Workday in Unified.to involves navigating to Active Integrations, searching for Workday, and entering the necessary credentials and endpoints.
