Privacy API Design Patterns

Overview

Privacy APIs provide programmatic interfaces for data subject rights exercise, consent management, data deletion, and audit logging. Well-designed privacy APIs enable organizations to automate compliance workflows, integrate with consent management platforms, and provide data subjects with self-service privacy controls. This skill covers API design patterns, OpenAPI specifications, authentication, and error handling for privacy-critical endpoints.
