What data in the http request is sent via parameters, and what data via the request body?

Question

Web development

What data in the http request is sent via parameters, and what data via the request body?
Let's say a GET request that returns some data based on the IDs that I pass to it.
Let's say I need to send 200 such IDs in one request. After all, I can do it both through a parameter (pass an array), or I can do it in the body, but what is the correct option?
