course_catalog_prices_apply

# course_catalog_prices_apply

Saves or removes the individual sale price of a class catalog in the Course app (pApp C00007). Shows a preview first; the change runs only after confirmation. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.
