I want to create a course with reverse week format by using the webservice. What do I have to set in the parameters?

courses[0][forcetheme]= string
courses[0][courseformatoptions][0][name]= string
courses[0][courseformatoptions][0][value]= string
courses[0][customfields][0][shortname]= string
courses[0][customfields][0][value]= string

Thanks for help
