Enterprise Healthcare API Management: Authentication, Authorization, and Rate Limiting for Regulated Environments

Abstract	The digital transformation of healthcare systems has led to the rapid adoption of Application Programming Interfaces (APIs) as the foundational mechanism for secure and scalable health data exchange. However, the sensitive nature of healthcare data, combined with strict compliance requirements under regulatory frameworks such as the Health Insurance Portability and Accountability Act (HIPAA), necessitates a robust and comprehensive approach to API management. This paper addresses the critical need for enterprise-level API governance frameworks tailored specifically to regulated healthcare environments, with a focus on three key pillars of API security and reliability: authentication, authorization, and rate limiting. The proposed framework introduces a holistic API management model that integrates leading practices in authentication through standards-based OAuth 2.0 and OpenID Connect implementations, enabling secure token issuance and lifecycle management. It further implements fine-grained Role-Based Access Control (RBAC) policies that restrict API access based on user roles and contextual rules. This ensures that clinicians, administrators, and external systems can only access the data necessary for their specific functions, thereby enforcing the principle of least privilege and mitigating the risks of unauthorized exposure.
