Symfonyapi Platform Serialization

Api Platform Serialization (Symfony)

Use when

• Designing or evolving API Platform contracts and operations.
• Aligning serialization, validation, and security behavior.

Default workflow

1. Define operation-level contract and payload boundaries.
2. Implement resource/DTO/provider/processor changes with explicit mapping.
3. Apply operation-specific validation and security constraints.
4. Validate functional behavior across happy and negative paths.

Guardrails

• Keep API contract explicit and version-aware.
• Avoid exposing internal entity fields implicitly.
• Prevent drift between docs and actual serialization.

Progressive disclosure

• Use this file for execution posture and risk controls.
• Open references when deep implementation details are needed.

Output contract

• API artifacts changed (resource/DTO/provider/processor).
• Contract/security decisions and rationale.
• Functional verification results.
