Brevo PushOwl integrates with Shopify Flow as a Flow Action, enabling you to send custom events from any Shopify Flow trigger directly to Brevo. This powers advanced marketing automations that go beyond the standard order and customer events that Brevo PushOwl syncs automatically.
If you are already using Shopify Flow with Brevo PushOwl to send push notifications or SMS, see the existing guide: Using Shopify Flow with PushOwl.
How It Works
The Track an Event action connects Shopify Flow to Brevo through Brevo PushOwl:
Shopify Flow detects a trigger: Any event in your store (order placed, customer tagged, product restocked, etc.)
Flow executes the "Track an Event" action: Brevo PushOwl receives the event data with the customer email, event name, and any custom properties
Brevo PushOwl forwards the event to Brevo: The event appears under Brevo → Automations → Logs → Event logs, where you can verify it was received
Brevo Automations trigger: Any Brevo Automation configured to listen for that event name will execute
Prerequisites
Before using the Track an Event action, ensure:
Brevo PushOwl is installed on your Shopify store
Data sync is complete: Your Brevo sub-account must be set up and connected to Shopify via PushOwl
Shopify Flow access: Available on Shopify Basic plan and above
No additional configuration is needed in Brevo PushOwl. The Track an Event action is available automatically once your store is connected.
Creating a Custom Event Flow
This walkthrough shows how to send a custom event to Brevo whenever an order is placed by a high-value customer, in this example, a customer whose lifetime amount spent in your store is greater than 1000.
Step 1: Open Shopify Flow
In your Shopify admin, click on Shopify Flow under Apps to get started.
Step 2: Create a Workflow
Click Create workflow to start a new Flow.

Step 3: Select a Trigger
Click Select a trigger and choose the event you want to react to. In this example, we use Order created.

Step 4: Choose "Order created"
Search for and click Order created in the list of Shopify triggers.
Searching for and selecting the Order created trigger.
Step 5: Add a Condition
Click Add condition and configure a filter on the order. For this example, set customer → amountSpent greater than 1000. This checks the customer's lifetime amount spent in your store, so the event fires only for your high-value customers.
Adding a condition that checks if the customer's lifetime amount spent is greater than 1000.

Step 6: Choose the True Branch
