Control API Platform serialization groups dynamically by implementing context builders that switch normalization groups based on user roles and request context. This allows role-based output without polluting entity models with conditional logic.

Add computed fields to API Platform responses by implementing custom normalizers. Normalizers calculate derived fields and format data during serialization, keeping entity models clean and separating presentation logic from domain models.

Prevent data leakage in API Platform serialization by managing nested relationships with depth controls and ignore rules. Define specific serialization groups across entities to selectively include or expose fields based on operation and context.

Yes, you can define serialization groups across entities to selectively include or expose fields based on operation and role. Configure normalizationContext groups and use context builders to adapt outputs for different client types and requests.

Yes, the approach combines custom normalizers for computed fields with context builders for dynamic group switching. This cohesive pattern centralizes serialization control across resources, roles, and contexts in Symfony API Platform projects.

Use custom normalizers in API Platform when you need computed fields, derived data, or custom formatting that serialization groups alone cannot handle. Normalizers process data during serialization while groups only select which entity fields to expose.
