Any HTTP request parameters will be automatically resolved as regular ETL graph parameters. Use standard ${PARAM} notation when using them in component attributes or in your graph logic.

In case of name conflict, i.e. having both a regular graph parameter and a HTTP request parameter with identical name, use request prefix to explicitly reference HTTP request parameter, e.g. ${request.PARAM}.

Parameters can also be accessed in CTL code using the getRequestParameter function. For multivalue parameters use the getRequestParameters(param_name) function which returns a list of values.
