Request Validation
The Request Validation policy is used to validate incoming requests based on schemas in OpenAPI specifications.
When configured, any requests that do not conform to your OpenAPI schema will be rejected with a 400: Bad Request
response containing a detailed error message (in JSON) explaining why the request was not accepted.
