How is data transferred in an ajax GET call?

Question

Forgive me if this is a stupid quesiton but I fell upon an ajax call of type GET that for some reason passed some data along with it. And I thought to myself, who passes data along with a GET request?

$.ajax({
     url: "https://example/api/jobFinished/",
     dataType: "JSONP",
     type: "GET",
     jsonpCallback: "callback",
     data: {
         id: '1852',
         scid: '1952',
         cid: '120125'     
     },

How is data transferred in an ajax GET request?

secondary question: Why would anyone choose to transfer data with an ajax GET request as opposed to an ajax requets of type POST?

I don't understand your question. Logically, if you want to GET something from a server, you need to tell it WHAT you want to get; and to do that, you have to pass some data to the server. — Robert Harvey, Aug 24 '18 at 14:52
It _should_ pass them as query parameters (?id=1852&scid=1952...), as to why you might pass data with a GET is to stick to convention, if you want to _get_ something from a server it'd be silly to use something called POST — George, Aug 24 '18 at 14:53
`data` on requests that don't support a body (like a GET request) are passed as query strings. It's just a convenience jQuery provides so you can use the same method template for all sorts of requests. — apokryfos, Aug 24 '18 at 14:55

How is data transferred in an ajax GET request?

On the query string. For example:

https://example/api/jobFinished/?id=1852&scid=1952&cid=120125

You can observe this in your browser's debugging tools by watching the requests and responses.

If the server is expecting a GET and not a POST. Conventions suggest that one uses GET when only querying and not modifying data.

So bascially that ajax func is basically just converting all the data into a query string and sending that? – Ryan Cameron Aug 24 '18 at 14:55
@RyanCameron: Basically, ya. A GET request has no body, only a request to a URL, so that would be where the data has to go. – David Aug 24 '18 at 14:58
