Can we validate json message against json schema in APIGEE?

[#1]

I could see that Message Validation policy can validate that json message is well-formed ,and also xml or soap with xsd.But is there any way to validate json message against json schema?

I want to validate incoming json message against its length and data type.What is the way to do this in proxy?

You can do this in two ways

1. Node.js

There are some node.js libraries to validate a JSON.

https://www.npmjs.com/package/jsonschema

You can run these node.js validator on edge in combination of proxy chaining and achieve the desired functionality.

2. Java Callout.

There are some java libraries that can do do JSON /SOAP/XSD validation. You can write a java callout policy to validate your JSON/XML .
