How to pass complete JSON content in XML tag.

Hi Team,

We want to pass JSON in XML tag of Item API. Once JSON saved successfully, we will extract JSON data in Web Report by using "JSONExtract" formula. But unfortunatly Our JSON data is not getting save if we post the data from Input Interface - Item XML API.

However the same JSON data is being save if we upload the data from Input Interface - Item Excel upload screen. We belive the same behaviour should be done by system if we post the JSON data by using Input Interface XML API.

Our objective is that, we want to save JSON data through Integration. So we want to know what is the correct syntax to post JSON in XML tag.
