I am having trouble finding a list the required parameters for each api call.
For example, this call works fine, as it does not require any parameters:
core_course_get_courses
However, as another example, when I attempt any of these three, I get an error because I do not know what parameters I need to submit with it:
core_enrol_get_enrolled_users
core_enrol_get_users_courses
core_enrol_search_users
These three calls return:
[exception] => invalid_parameter_exception
[errorcode] => invalidparameter
[message] => Invalid parameter value detected
So where can I find these api calls with a list of the required parameters for each.
