# Class Alert Lists and Push Notifications

HTML version: [Class Alert Lists and Push Notifications](https://support.gladstonesoftware.cloud/gooperator/class-alert-lists-and-push-notifications)

## Problem
You want members to be able to join a **Class Alert List** for a full class on Go Book and be emailed, or sent a push notification in the Go mobile app, when a space opens, so cancelled places are filled.

## Resolution

### Set up the class alert list

1. **Turn on the waiting list in Plus2**
   - Go to `Plus2 > Configuration > Bookings` and open the reservation or class.
   - Tick **Waiting List** and click **Save**.
   - Details: [Enabling the Alert List for Classes in Gladstone Go](enabling-the-alert-list-for-classes-in-gladstone-go.md).

2. **Set the alert rules in Operator**
   - Go to `Operator > Modules > Configure`, search **Waiting List** (related settings also appear under **alert list**), and set the enable switch, opening window, **Cut Off Period in Minutes**, **Deeplink base URL**, **Excluded Price Levels**, **Excluded Statuses**, **Search Duration in Hours** and **Sites To Search For**.
   - What each setting does, with recommended values: [GladstoneGo: Alert List Notification Setup](gladstonego-alert-list-notification-setup.md).

3. **Personalise the email**
   - Edit the waiting-list email template in `Automation Portal > Email Templates`. Give it a friendly subject such as "Space available on your class".

4. **Create the communication job**
   - Go to `Automation Portal > Communication Jobs` and add a job using the **Fill space in class from a waiting list** type and the class alert email template, set to repeat several times a day.
   - Run it more often than your online **cancellation cut-off** (for example, hourly or every 30 minutes), or late cancellations will not trigger an alert in time.

### Add push notifications (Go mobile app) (if applicable)

5. **Switch push notifications on in Operator**
   - Go to `Configuration > Modules > Configure`.
   - Search **Enable Push Notifications** and set it to **1** (True). Click **Save**.
   - Search **OneSignal App ID**, enter the ID supplied by Gladstone and click **Save**.

6. **Add push to your class alert job**
   - The push toggle appears once the **class alert email template** is selected in the job.
   - **New job**: `Automation Portal > Communication Jobs > +` > name > frequency > class alert template > toggle **push notifications** on > edit the title and message (and other languages if used) > finish the set-up > **Save and Add Job**.
   - **Existing job**: open your class alert job > toggle **push notifications** on > edit if needed > **Save**.

## Notes

- When a class is full, members can join its Class Alert List. If a space opens, everyone on the list is emailed (and, if they use the Go mobile app, sent a push notification) at the same time. The first to book gets the place; the alert does not hold it.
- Alert lists work for **reservations (classes) only**, not activities.
- **What members see**: on a full class, a **Join the Class Alert List** button; an email when a space opens, with a link to book; and an option to **Remove me from the alert list**. Members can also remove themselves from `My Account > Class alerts`; tell them how.
- The email repeats on every run of the job while the space stays unfilled, so very short intervals spam customers.
- Without the **Waiting List** tick on the class in Plus2, the alert button does not appear, whatever Operator says. Gladstone can bulk-tick many classes for you; contact Gladstone Support.
- Changes in Plus2 can take about 20 minutes to show in Go. Members may also need to refresh their browser.
- Some third-party app providers treat the booked and waiting lists as one, so the class still shows as full. Customers should use the book link in the alert email.
- **Alert button missing on a full class**: check the alert list is enabled, the excluded price levels and statuses, and the Plus2 **Waiting List** tick.
- **Alert emails not sent or sent too late**: check the class alert job is running and its interval against the cancellation cut-off, and that emails are enabled on test.
- **Push notifications prerequisites**: the Go mobile app set up for your organisation, and a **OneSignal App ID** from Gladstone. If you do not have one, ask your Gladstone contact before starting. Push notifications currently work for class alert list messages only.
- **What app users see**: a push notification as well as the email when a space opens. Tapping it opens the class in the app (they may need to log in) so they can book. If the space has already gone, they see a message saying they have missed out. On Android, they can also choose to remove themselves from the alert list.
