What are query parameters and where are they displayed in the request?

Query parameters are part of a URL that are passed after the question mark (?) and contain key=value pairs separated by an ampersand (&). They are used to send data to the server in HTTP requests.

Example of a URL with query parameters:

https://example.com/search?query=golang&page=2&sort=asc

Here, query=golang, page=2, and sort=asc are query parameters.

They appear in the URL's query string after ? and allow the client to pass parameters for filtering, pagination, sorting, and other purposes without changing the URL path.
