How deeply does Secure APIs cover schema validation?

Explains payload conformance and rejection responses, but does not detail schema syntax or individual validation rules.

Schema validation

Schema validation is the checking of data against a defined schema's fields, types, structure, and constraints.

Schema validation checks whether an API request conforms to its defined data schema. A WAF can compare request payloads with the API specification and reject invalid requests with a useful error message and status code. section 9.4

This gives the WAF a structured way to distinguish acceptable API input from malformed or suspicious traffic, adding protection beyond application-level attacks. section 9.4

Rejecting a malicious request

A WAF may reject a request such as GET /payments?filter=' or 1=1-- when its content indicates SQL injection. Schema validation complements this filtering by enforcing the API specification for request payloads. section 9.4
