7. Price-Drop Notifications

The plugin can automatically send customers email notifications when products on their wishlists drop in price. Two things are required:

1. The feature is globally enabled in the plugin settings (active by default).

2. A Flow Builder flow is set up to send the email.

How Price Tracking Works

When a customer adds a product to a wishlist, the plugin automatically saves the current gross unit price and currency ID. This stored price serves as the reference for future comparisons.

A scheduled background task periodically checks all wishlist items for price changes. When the current price drops below the stored reference price (minus the configured threshold), a Flow Builder event is dispatched.

Note: The Scheduled Task Worker must be running. Without it, no checks are performed and no notifications are sent.

Configuring the Threshold

In the plugin settings under Price Drop Notifications, you can configure:

• Threshold type — Percentage or Absolute value

• Minimum price drop threshold — e.g. 5 for 5 % or €5

Only price drops that exceed the threshold trigger a notification. This filters out micro-fluctuations (e.g. from rounded currency conversions).

Setting Up the Flow Builder

The plugin provides the "Wishlist Price Drop" event (technically: momo_advanced_wishlists.price_drop) for the Flow Builder.

Step 1: Create a flow

1. Go to Marketing → Flow Builder.

2. Click Create flow.

3. Give the flow a descriptive name (e.g. "Price drop notification").

Step 2: Select the trigger

1. Click Add trigger.

2. Search for Wishlist Price Drop or scroll to the Wishlist category.

3. Select the event.

Step 3: Add an action

1. Click Add action.

2. Select Send email.

3. Choose a recipient — for customer notifications: Customer (Wishlist).

4. Select an email template or create a new one. The plugin automatically creates the "Wishlist Price Drop Notification" template during installation — you can select and use it right away.

Step 4: Design the email template

The following variables from the price-drop event are available in the email template:

Variable	Content
{{ customer }}	Customer object (firstName, lastName, email, id)
{{ priceDropItems }}	Array of affected items (see below)
{{ currencyIsoCode }}	Currency code (e.g. EUR)

Each element in priceDropItems contains:

Key	Content
productName	Product name
productId	Product ID
oldPrice	Original price (float)
newPrice	Current price (float)
savingsAmount	Savings amount (absolute, float)
savingsPercentage	Savings percentage (float)
productUrl	URL to the product in the storefront

Example Twig for the email template:

Hello {{ customer.firstName }},

the following products on your wishlists have dropped in price:

{% for item in priceDropItems %}
- {{ item.productName }}
  Was:  {{ item.oldPrice }} {{ currencyIsoCode }}
  Now:  {{ item.newPrice }} {{ currencyIsoCode }}
  You save: {{ item.savingsAmount }} {{ currencyIsoCode }} ({{ item.savingsPercentage }}%)
  View product: {{ item.productUrl }}
{% endfor %}

Best regards,
Your shop team

Step 5: Activate the flow

Make sure the flow is set to Active before saving.

Customer Opt-In

For a customer to receive notifications, they must enable the feature per wishlist:

1. Open the wishlist detail page in the storefront.

2. In the Price-drop notifications section, activate the toggle.

Customers can deactivate the toggle at any time. If the feature is globally disabled in the plugin settings, the toggle is hidden in the storefront.

Frequently Asked Questions

Are notifications sent for all price drops? No. Only price drops that exceed the configured threshold trigger a notification.

Is a notification sent each time the price drops further? Yes — each check where the price is below the stored reference price dispatches an event. The reference price is not automatically updated.

What happens if a product is removed from the catalogue? Items for which no price can be resolved are skipped during the check. No notification and no error message is triggered.
