What is the difference between JSON and JSONP in Salesforce?

Hi Suniti,

JSON: JSON is a simple data format used for communication medium between different systems
JSONP: It is a methodology for using that format with cross-domain ajax requests while not being affected by the same origin policy issue.

Thanks.

Hi,

To make it more simple -

JSONP is JSON with padding, that is, you put a string at the beginning and a pair of parenthesis around it. For example:

//JSON
{"helps":"old","age":55}
//JSONP
onOff({"helps":"new","age":65});

Hope this helps.
