Currently it is easy using the OTB to parameterize a REST APIs template/query/matrix/header parameter values to dynamically build a URI.
However there is no OTB functionality that allows the user to parameterize the parameter values themselves.
Im currently working on a project where the REST APIs query parameter names are actually database table column names. Any table attribute in the database is queryable so it would help a lot if there was OTB functionality to enable this.
