If your APIs handle personal data of EU residents, GDPR compliance is not optional. Many teams assume GDPR is only a legal concern, but in reality it must be enforced at the API and data architecture level. Poorly designed APIs expose too much data, lack consent controls, and make it impossible to respond to data subject requests. We design GDPR‑compliant APIs using Django REST Framework or FastAPI that embed privacy, control, and auditability directly into the system.
GDPR Challenges API Teams Face
-
APIs returning more personal data than necessary
-
No clear consent or purpose limitation enforcement
-
Difficulty responding to data access or deletion requests
-
Lack of audit trails for data usage
-
Hard‑coded data flows that violate privacy principles
-
High risk during compliance audits
