Notifications

WHMCS integrates with popular team communication apps, including Slack® and HipChat™, to allow WHMCS to notify you in real time as events occur.

You can access this feature at Configuration () > System Settings > Notifications.

Notifications in the Admin Area

Using conditions, you can set up WHMCS to notify you in your Slack channels and HipChat rooms about the events that are important to you. For example:

  • Notify my Support channel or room when a new ticket opens in the Support department with a High priority.
  • Notify my Enterprise Support channel or room when a new ticket opens or a customer in the Enterprise Customers client group replies.
  • Notify my Emergency channel or room when a new ticket opens containing the word Emergency in the subject.
  • Notify my Sales channel or room when someone places a new order with a value over $25.
  • Notify my Billing channel or room when a customer in the High Value client group pays an invoice.
  • Notify my Customer Service channel or room when a customer places an order for a Business Hosting product.

Configuring Notification Providers

WHMCS supports the following notification providers:

You can add your own notification providers by creating a custom notification module.

  • The Email module that ships with WHMCS is not encoded. You can copy it to use as a template for custom notification module development.
  • For more information, see our Developer Documentation.

Creating a Notification Rule

Notifications use rules. Each rule defines when to trigger a notification through a combination of events and conditions.

To create a new rule:

  1. Click Create New Notification Rule.
  2. Enter a name and description for your rule to allow you to easily identify it again later.
  3. Choose an event category.
    Selecting an event for a notification.
  4. Choose one or more events to trigger the notification within the selected event category. Ctrl+Click to select multiple events.
    You can add custom events using the WHMCS API. For more information, see Custom Notification Events.
  5. Configure any conditions you want to use to restrict when the system triggers the notification. The available conditions depend on the selected event category.
    Selecting a condition for a notification.
  • By default, all conditions default to unrestricted.
  • To apply a condition, select or provide a value for a given condition.
    • For free text-based conditions like Subject, you can choose from an exact match or a containing match.
    • For monetary value conditions like Order Total, you can specify a Greater Than or Less Than match.
  • You can create custom conditional logic using the NotificationPreSend hook point.
    For more information, see Advanced Notification Logic.
  1. Configure the notification provider.
    Selecting settings for a notification.

    For more information, see:

  2. Configure the notification settings.
    • The available notification settings will depend on the provider that you selected. For example, for HipChat and Slack, you must select a room or channel, and then can set the desired message.
    • HipChat also allows you to set whether the notification triggers an alert like a sound or mobile notification.
  3. Click Create.

Notification Rules

The list of notification rules includes all of the rules on your WHMCS installation.

Enabling and Disabling Notifications

To enable a notification rule, set the toggle to ON, or set the toggle to OFF to disable it.

Edit a Notification Rule

To edit a notification rule, click the pencil icon for that notification rule.

Duplicate a Notification Rule

To duplicate a notification rule, click the copy icon. Customize the configuration that displays and then click Duplicate.

Delete a Notification Rule

To delete a notification rule, click the trash can icon and then confirm the deletion.

Deleting notification rules is permanent. We recommend disabling rules instead of deleting them.

Advanced Notification Logic

You can customize notification conditions further using the NotificationPreSend hook point. The NotificationPreSend hook point executes prior to the system sending a notification. This allows you to apply additional conditional criteria and manipulate the notification message.

You can also use this hook point to prevent sending a notification that uses your logic.

For example, the following hook code would prevent WHMCS from sending notifications for invoices with an invoice ID that is greater than 1000:

<?php

add_hook('NotificationPreSend', 1, function($vars) {

    $eventType = $vars['eventType']; // e.g. "Ticket", "Invoice", "Order", "Service" or "Domain"
    $eventName = $vars['eventName'];
    $rule = $vars['rule'];
    $hookParameters = $vars['hookParameters'];
    $notification = $vars['notification'];

    // Perform additional conditional logic and throw the AbortNotification
    // exception to prevent the notification from sending.
    if ($eventType == 'Invoice'
        && $eventName == 'created'
        && (isset($hookParameters['invoiceid'])
        && $hookParameters['invoiceid'] > 1000)
    ) {
        throw new \WHMCS\Notification\Exception\AbortNotification();
    }

    // If allowing the notification to continue, you can manipulate the
    // notification using the \WHMCS\Notification\Notification object.
    $notification->setTitle('Override notification title');
    $notification->setMessage('Override notification message body');

});

To prevent the notification, the system returns a \WHMCS\Notification\Exception\AbortNotification(); exception.

If the ID is below 1000, the system will continue to send the notification, but will override the title and message.

To override values, use the set functions in $notification.

For more information, see our Internal Class Documentation.

Custom Notification Events

You can use the TriggerNotificationEvent WHMCS API function to create custom notification events. This allows you to augment the already-available list of events that you can choose when setting up a notification rule at Configuration () > System Settings > Notifications.

Creating a Custom Event

To create a custom event, call the TriggerNotificationEvent API function in your custom code.

For example, the following code creates an event that uses the AdminLogin hook to trigger a notification whenever an admin logs in to the Admin Area:

<?php
add_hook('AdminLogin', 1, function($vars) {
    $command = 'TriggerNotificationEvent';
    $postData = array(
        'notification_identifier' => 'adminarea.staff.login', // A unique identifier used when referencing the notification rule.
        'title' => 'A Staff Member Just Logged In',
        'message' => $vars['username'] . ' just logged in to the WHMCS Admin Area.',
        'url' => 'https://whmcs.example.test/admin/',
        'status' => 'Success',
        'statusStyle' => 'info',
    );
    $adminUsername = 'ADMIN_USERNAME'; // Optional
    $results = localAPI($command, $postData, $adminUsername);
    print_r($results);
});

Make certain that you include a unique notification_identifier value. You will use this identifier when you configure notification rules for this event.

Using Custom Events

After you create your custom code, you must still create a notification rule using the event.

To do this:

  1. Go to Configuration () > System Settings > Notifications.
  2. Click Create New Notification Rule.
  3. Enter a name and description for your rule to allow you to easily identify it again later.
  4. Select API as the event category.
  5. Select Custom API Trigger as the event.
  6. For Trigger Identifier, enter the notification identifier that you specified in your custom code. In the example above, this is adminarea.staff.login.
  7. Select Exact Match.
  8. Configure the notification provider.

    For more information, see:

  9. Configure the notification settings.
    For more information, see Notifications.
  10. Click Create.

Whenever you trigger the API call in your custom code, the system will send the configured notification.
