I'm attempting to use GET requests to get all the course categories in my moodle server, however I am getting this error with the following GET request:
/webservice/rest/server.php?wstoken=***&wsfunction=core_course_get_categories
<EXCEPTION class="webservice_access_exception">
<ERRORCODE>accessexception</ERRORCODE>
<MESSAGE>Access control exception</MESSAGE>
</EXCEPTION>
The request is successful however when I try to list all the courses using the request below.
/webservice/rest/server.php?wstoken=***&wsfunction=core_course_get_courses
Anyone see what I'm doing wrong?
