JSONP Requests ('callback')

If you need to receive your API response wrapped inside a JSONP callback function, you can use the callback query parameter with any valid API route. The data will be returned wrapped in the callback function you specify.

The callback value can be any valid JavaScript method name.

The entire JSON API response will be delivered wrapped in the requested callback function.
