I have a two domains, example1.com and example2.com
From example1.com, I would like call a JSON API I have on example2.com. Knowing that this is not allowed, it occurred to me - this is exactly why JSONP was created.
Question is, how do I modify my JSON API to make it JSONP capable?
Basically, how do I create the callback api?
UPDATE
My server side language is PHP
