[Resolved] Syntactical error in REST JSON

Hi,

So that means when you get this type of response, we basically we should check with the service first before make a decision regarding the request.

Yes, you should know ahead of time if the service expects xml, json, or can handle both.

Is there a way to identify these types of issue by examine the logs?

You will have to look at the error messages you receive and make that determination.
Also review the documentation for your web services.
