Current situation

Currently there's no validation available for JSON messages in REST requests. The only thing to do with JSON is to format it:

For SOAP requests the validation works pretty well:

- it validates if the XML is well formed

- it validates XML against WSDL/XSD 

The need

For instance, I have a REST POST request with a large JSON document.

I need to validate if:

• the document is a well formed JSON
• the document conforms to the API specification (OpenAPI)

Can you please add this function, at least for JSON as the most commonly used format in REST?

I would suggest also a check and warning for invisible characters and encoding within the request -- if they come into the request e.g. by copy-pasting, it's very difficult to realize what's wrong. In such cases other tools may work fine (e.g. curl) having the same HTTP headers but still ReadyAPI request fails.
