How to resolve missing closing quote 'character ' on string error message in Salesforce?

Hi Deepak,

Apex doesn't allow multiline string literals, So you need to quote that JSON line by line, and add new lines via 'n':-

request.setBody('{ n' +
' "Fields" : [{ n'+
' "Field" : "Name",n' +
' "Data" : "Palo Alto Networks"n'+
' }n'+
' ] n'+
' } n'
);
