Cannot add GET query Parameters to webhook

We’re trying to use webhook to make a rest api call (GET https://host:port/path?id={entryId}) which triggers a job. We do get an option to change the Http Method to GET, but we cannot understand how to provide query params based on the updated entry.
Also, the content-type available is either json or form-urlencoded, which are both not applicable for a GET call. Do we keep them the same?
