symfony:api-platform-resources

Define explicit API Platform contracts in Symfony by specifying operation-level payloads, mapping resources to DTOs, and enforcing policy-safe behavior for serialization and validation. This approach ensures clear boundaries and avoids exposing internal entity fields.

Separating DTOs from internal entities in Symfony API Platform requires explicit contract definition alongside provider and processor mapping. This configuration aligns serialization boundaries and prevents unintended internal field exposure during API responses.

Configure operation-specific validation and security constraints for API Platform resources by defining explicit policies within each operation contract. This alignment ensures payload validation and security checks execute precisely per endpoint.

API Platform supports version-aware contract evolution in Symfony by mapping resource and DTO changes explicitly. This process maintains serialization and security alignment across API versions during endpoint development.

Internal entity fields appear in API Platform Symfony responses when contracts lack explicit payload boundaries. Defining dedicated DTOs and explicit operation mapping resolves the issue by enforcing strict serialization limits.
