Zoom welcome message to Participants

[ferozsho]

Hi,

Currently, when a Zoom meeting is created, there is no automatic email sent to enrolled users, similar to the registration confirmation emails Zoom sends out. I noticed the Send iCal notifications task and was wondering if it could be integrated or if a separate branch could be provided. This would allow us to pull and utilize the method for sending invitation emails to enrolled users.

I appreciate your attention to this matter.

For the time being, I've incorporated the Zoom plugin file and invoked the 'zoom_add_instance' function.

htdocs/mod/zoom/classes/webservice.php

    public function post_registrants_meeting($meetingId, $webinar, $user)
    {
        $res = new stdClass();
        $res->status = true;
        $res->data = 'Success';

        if (empty($user->email)) {
            $res->status = false;
            $res->data = 'User email not present!';
            return $res;
        }

        try {
            $url = ($webinar ? 'webinars/' : 'meetings/') . $meetingId . '/registrants';
            $data = [
                'email' => $user->email,
                'first_name' => $user->firstname,
                'last_name' => $user->lastname,
                'auto_approve' => true,
            ];
            $this->make_call($url, $data, 'post');
        } catch (moodle_exception $error) {

            if (strpos($error->getCode(), 1010) === true) {
                $res->status = false;
                $res->data = 'User does not belong to this account';
            } else {
                $res->status = false;
                $error->data = $error->getMessage();
            }
        }

        return $res;
    }

#452 needs some changes. I reviewed it a couple times, but the remaining issues need to be resolved before it can be merged. Unfortunately, I do not have time to work on it myself.

It sounds like you have instead started to implement #504, automatically registering all users when an activity is created. For completeness, you will need to make sure to automatically register a user for all Zoom activity that already exist in the course at the time when the user enrolls into the course. That way people who join the class after the Zoom activities have been created will be registered for the meetings.

Additional complexity: Activities with access restrictions must be honored. So only people who meet the access restrictions can be registered (added to a group, removed from a group, conditional availability, time-based, and more).

The only scalable option that we can think of is to track which meetings a user has been registered for. When a user access the course, we can compare the set of meetings that they were previously registered for with the set of meetings that they currently have access to; then add the new meetings and remove the old meetings via Zoom's API. To mitigate the situation where a student does not log in to Moodle for a period of time, we can update all users periodically, such as once-a-day or when a Zoom activity is updated.

New table, something like:

zoom_registration
id, user.id, course.id, cm.id, zoom.id, registration time(int)
