User web service functions do not trigger user events.

Create a local plugin with /local/YOURLOCALPLUGIN/db/events.php : $handlers = array ( 'user_created' => array ( 'handlerfile' => '/local/YOURLOCALPLUGIN/lib.php', 'handlerfunction' => 'YOURLOCALPLUGIN_user_created', 'schedule' => 'instant' ), 'user_updated' => array ( 'handlerfile' => '/local/YOURLOCALPLUGIN/lib.php', 'handlerfunction' => 'YOURLOCALPLUGIN_user_updated', 'schedule' => 'instant' ), ); in /local/YOURLOCALPLUGIN/lib.php: function YOURLOCALPLUGIN_user_created ($user) { error_log(print_r('An user has been created - wstemplate Tester plugin event handler', true)); error_log(print_r($user, true)); }   function YOURLOCALPLUGIN_user_updated ($user) { error_log(print_r('An user has been updated - wstemplate Tester plugin event handler', true)); error_log(print_r($user, true)); } Then call the web service 'create users' and 'update users' functions with a ws client ( https://github.com/moodlehq/sample-ws-clients ) You should see the error logs meaning that the events have been correctly triggered.
