How do I implement API Request Validation?

Use libraries or frameworks that parse and validate request payloads (e.g., JSON Schema validators). Implement checks at the gateway or microservice level before processing the request.

Why is API Request Validation important for security?

Validating requests blocks injection attacks, malformed payloads, and other malicious inputs, helping maintain system integrity and prevent data corruption or unauthorized access.

What are best practices for request validation error handling?

Provide descriptive error messages with HTTP status codes (e.g., 400 for bad requests). This helps developers quickly identify invalid data and correct their requests.
