JSON input parameter for service

Hello Community,

I am sending jsonData which is my input parameter of the service from my mashup and it goes like this in the picture below.

I am unable to read it in the service. I know the methods JSON.parse and JSON.stringify but still i am not getting it. I am unable to read the data. why its converting the json in this format.

I dont why my json is getting converted with double serialization with extra back slashes.

• Single Serialization: When you serialize a JSON object, it should be converted to a JSON string with necessary escape characters.
• Double Serialization: If the JSON string is serialized again or if escape characters are added improperly, it results in a string with extra backslashes.
•  

my json in mashup. its hardcoded i have written.
