 This way, a single string parameter passes an arbitrary number of input pairs (path variable and an associated ID) to the parameterized query. The number of required parameters no longer depends on the input, and the updated code can be black-boxed. The only remaining task is to add a new interface query, *json_object_data*, at the top and add code, converting *json_object_data* input to *string_data* format. The following snippet replaces the original *string_data* block:
