Consider Pega’s OOTB update case API V1 /cases/{ID}, you’ll see two parameters called actionID & If-Match are required to be passed. actionID is an example query parameter and If-Match is an example of header parameter.

Headers in a REST service are typically used for passing additional information along with the request, such as authentication tokens, correlation IDs, or custom metadata. In order to access headers in an OOTB service, you can use the HttpServletRequest object to retrieve the request headers.
