Can we use OAS 3.x in APIGEE to validate the ENUM or JSON Request Payload

[ahmars]

Hi there,

Can we use OAS 3.x in APIGEE to validate the enums OR the JSON Request Payload as a whole instead of manually putting the validations in javascript and/Raising the fault.

Also, is it advisable to use RegEx policies to handle OWASP vulnerabilities for SQL injection/XSS or we should use a third party library, please suggest with an example.

Kindly Help.

Thanks
