How it works

Revize fires a Shopify Flow trigger whenever a customer edits their order. You connect that trigger to Klaviyo’s “Track an Event” action, which sends the order data to Klaviyo. From there, you build a Klaviyo Flow to send the email. Revize trigger → Shopify Flow → Klaviyo event → Klaviyo email

Available triggers

You can send Klaviyo emails for any of these Revize triggers:

Order edited — fires on any order edit, including product changes and discount code edits
Shipping address updated
Email address updated
Phone number updated
Delivery date updated
Order cancelled
Support ticket created
Tax invoice generated

Each trigger follows the same setup process. Only the trigger you select in Shopify Flow, the event name you send to Klaviyo, and the event properties change.

Part 1: Set up Shopify Flow

Step 1: Find your Klaviyo Public API Key

Go to your Klaviyo dashboard.

Open Settings

Click your account name in the bottom-left corner, then go to Settings.

Navigate to API Keys

Go to the API Keys section.

Copy your Public API Key

Copy the Public API Key (a short alphanumeric code). You will need this in Step 3.

Make sure you copy the Public API key, not the Private API key. The public key is the shorter one.

Step 2: Create a Shopify Flow workflow

Open Shopify Flow

In your Shopify Admin, go to Apps → Shopify Flow and click Create workflow.

Select a Revize trigger

Click Select a trigger, search for Revize, and choose the trigger you want (e.g., Order edited, Shipping address updated, etc.).

Add a Wait action

Click the + below the trigger and add a Wait action. Set the duration to 10 seconds.

Add a Get Order Data action

Click the + below the Wait step and add a Get Order Data action (Shopify action).Configure it as follows:

Set Select a query to Advanced
In the Edit query field, enter: id:{{order.legacyResourceId}}
Set Maximum number of orders to 1
Set Sort data by to Updated at, Descending

Why the 10-second wait? It gives Shopify’s API time to reflect the latest order changes before fetching fresh data. The Get Order Data step then pulls the correct current line items and variants.

Step 3: Add the Klaviyo “Track an Event” action

Search for Klaviyo

In the actions list, search for Klaviyo and select Track an Event.

Fill in the fields

Use the table below to fill in each field.

Field	Value
Klaviyo Public API Key	Your Public API Key from Step 1
Event Name	See the event name table below
Customer Email Address	`{{order.customer.email}}`
Customer First Name	`{{order.customer.firstName}}`
Customer Last Name	`{{order.customer.lastName}}`

Event names by trigger

Use a descriptive event name so you can identify each trigger in Klaviyo:

Revize Trigger	Recommended Event Name
Order edited	`Revize_Order_Edited`
Shipping address updated	`Revize_Address_Updated`
Email address updated	`Revize_Email_Updated`
Phone number updated	`Revize_Phone_Updated`
Delivery date updated	`Revize_Delivery_Date_Updated`
Order cancelled	`Revize_Order_Cancelled`
Support ticket created	`Revize_Support_Ticket`
Tax invoice generated	`Revize_Tax_Invoice`

You can name these events anything you like. These are just our recommended names to keep things organized.

Step 4: Set Customer Properties

In the Customer Properties field, paste the following JSON:

{
  "$email": "{{order.customer.email}}",
  "$first_name": "{{order.customer.firstName}}",
  "$last_name": "{{order.customer.lastName}}"
}

This tells Klaviyo which customer profile to associate the event with.

Step 5: Set Event Properties

In the Event Properties field, paste the JSON that matches your trigger. This uses freshly fetched order data from the Get Order Data step, so Klaviyo always gets the correct current data.

Order Edited
Address / Email / Phone / Delivery Date
Cancellation

Use this when you want to send the full updated order details, including line items:

{% for single_order in getOrderData %}
{
  "order_id": "{{single_order.id}}",
  "order_name": "{{single_order.name}}",
  "order_number": "{{single_order.legacyResourceId}}",
  "total_price": "{{single_order.totalPriceSet.shopMoney.amount}}",
  "subtotal_price": "{{single_order.subtotalPriceSet.shopMoney.amount}}",
  "total_tax": "{{single_order.totalTaxSet.shopMoney.amount}}",
  "total_shipping": "{{single_order.totalShippingPriceSet.shopMoney.amount}}",
  "currency": "{{single_order.currencyCode}}",
  "edited_at": "{{single_order.updatedAt}}",
  "customer_email": "{{single_order.customer.email}}",
  "customer_name": "{{single_order.customer.firstName}} {{single_order.customer.lastName}}",
  "line_items": [{% assign comma = "" %}{% for item in single_order.lineItems %}
    {% if item.currentQuantity != 0 %}{{comma}}
    {"title": {{item.title | json}}, "quantity": {{item.currentQuantity}},
     "price": "{{item.originalUnitPriceSet.shopMoney.amount}}",
     "variant_title": {{item.variantTitle | json}}, "sku": {{item.sku | json}}}
    {% assign comma = "," %}{% endif %}
  {% endfor %}]
}
{% endfor %}

Do not wrap the line_items array brackets [ ] in quotes. The brackets must be outside all quotes for Klaviyo to receive a proper array.

Use this for shipping address, contact info, or delivery date updates. Sends order summary without line items:

{% for single_order in getOrderData %}
{
  "order_id": "{{single_order.id}}",
  "order_name": "{{single_order.name}}",
  "order_number": "{{single_order.legacyResourceId}}",
  "total_price": "{{single_order.totalPriceSet.shopMoney.amount}}",
  "currency": "{{single_order.currencyCode}}",
  "updated_at": "{{single_order.updatedAt}}",
  "customer_email": "{{single_order.customer.email}}",
  "customer_name": "{{single_order.customer.firstName}} {{single_order.customer.lastName}}",
  "shipping_address": "{{single_order.shippingAddress.address1}}, {{single_order.shippingAddress.city}}, {{single_order.shippingAddress.province}} {{single_order.shippingAddress.zip}}, {{single_order.shippingAddress.country}}"
}
{% endfor %}

Use this for order cancellation events:

{% for single_order in getOrderData %}
{
  "order_id": "{{single_order.id}}",
  "order_name": "{{single_order.name}}",
  "order_number": "{{single_order.legacyResourceId}}",
  "total_price": "{{single_order.totalPriceSet.shopMoney.amount}}",
  "currency": "{{single_order.currencyCode}}",
  "cancelled_at": "{{single_order.updatedAt}}",
  "customer_email": "{{single_order.customer.email}}",
  "customer_name": "{{single_order.customer.firstName}} {{single_order.customer.lastName}}"
}
{% endfor %}

The {% for single_order in getOrderData %} loop reads from the freshly fetched order data, not the original trigger. This ensures correct data every time.

Step 6: Turn on the workflow

Review all fields

Make sure everything is filled in correctly.

Turn on the workflow

Click Turn on workflow in the top-right corner.

Done

The workflow is now active. Every time a customer triggers that action through Revize, the event is sent to Klaviyo with up-to-date order data.

Part 2: Set up the Klaviyo email

Step 7: Create a Klaviyo Flow

Create a new Flow

In Klaviyo, go to Flows → Create Flow and select Build your own.

Set the trigger

For the trigger, choose Metric and search for the event name you used (e.g., Revize_Order_Edited).

Add an email action

Drag an Email action into the flow.

Design your template

Use the variables below to pull in order data dynamically.

Step 8: Email template variables

Use these variables in your Klaviyo email template:

Data	Klaviyo Variable
Customer Name	`{{ event.customer_name }}`
Order Number	`{{ event.order_name }}`
Subtotal	`{{ event.subtotal_price }}`
Total Tax	`{{ event.total_tax }}`
Shipping	`{{ event.total_shipping }}`
Total Price	`{{ event.total_price }}`
Currency	`{{ event.currency }}`
Edit Date	`{{ event.edited_at }}`
Customer Email	`{{ event.customer_email }}`
Shipping Address	`{{ event.shipping_address }}`

Displaying line items

To display each product in the edited order, use this loop in your Klaviyo email template:

{% for item in event.line_items %}
  {{ item.title }}
  Variant: {{ item.variant_title }}
  Qty: {{ item.quantity }}
  Price: {{ item.price }}
{% endfor %}

Wrap this loop in a table or styled HTML in your Klaviyo email template to match your brand.

Example email

Here is an example of how your email subject and body might look:

Subject: Your order {{ event.order_name }} has been updated

Hi {{ event.customer_name }},

Your order has been updated. Here is your revised summary:

{% for item in event.line_items %}
  {{ item.title }} ({{ item.variant_title }})
  Qty: {{ item.quantity }}  |  Price: {{ item.price }} {{ event.currency }}
{% endfor %}

Total: {{ event.currency }} {{ event.total_price }}

Prevent duplicate emails

If a customer makes multiple quick edits in one session, Klaviyo may send multiple emails. To prevent this:

Open your Klaviyo Flow
Add a Flow Filter
Set it to suppress if the customer received this email in the last 5 minutes

Troubleshooting

Flow shows 'Succeeded' but no event in Klaviyo

Double-check that the Public API Key in Shopify Flow matches the one in your Klaviyo account. This is the most common issue.

Event arrives but data is empty

The Event Properties JSON may be invalid. Make sure there are no line breaks inside string values and that line_items uses [ ] brackets without surrounding quotes.

Wrong variant showing in line items

Make sure you are using the Get Order Data step with the 10-second wait, and that your Event Properties use the getOrderData loop, not order.lineItems directly.

Multiple emails being sent

Add a Flow Filter in Klaviyo to suppress if the customer received this email in the last 5 minutes.

Where to find the metric in Klaviyo

Go to Analytics → Metrics and search for your event name (e.g., Revize_Order_Edited). It is created automatically the first time an event is received.

How to verify it worked

Go to Audience → Profiles in Klaviyo, find the customer email, and check their Activity tab for the event.

Want multiple triggers?

You can set up separate Shopify Flow workflows for each trigger. For example:

Workflow 1: Order edited → Revize_Order_Edited → “Your order has been updated” email
Workflow 2: Address updated → Revize_Address_Updated → “Your shipping address has been changed” email
Workflow 3: Order cancelled → Revize_Order_Cancelled → “Your order has been cancelled” email

Each workflow follows the same steps above. Just change the trigger, event name, and event properties.
