Multi-solution licensing server architecture validates customer licenses across VAS, HR, and BES integrations via HTTPS endpoints. Client applications authenticate via POST /auth/token, then request license metadata through POST /api/jsData, with all requests routed to a centralized License Server Core. The License Server queries a relational database storing companyCode, taxCode, licenseKey, activation and expiration dates, and appcode, then validates each license against activation status and expiration windows. This hub-and-spoke pattern ensures consistent license enforcement across heterogeneous solutions while maintaining a single source of truth for license state.
