Klaviyo Device Mode Integration
Send events to Klaviyo using RudderStack device mode.
RudderStack lets you send your event data to Klaviyo via device mode using the native web SDK.

RudderStack loads the Klaviyo native SDK from
https://static.klaviyo.com/ domain. Based on your website’s content security policy, you might need to
allowlist this domain to load the Klaviyo SDK successfully.
Identify
The identify call lets you identify a visiting user and associate them to their actions. It also lets you record the traits about them like their name, email address, etc.

You can send any number of key-value pairs as user traits and RudderStack updates them as
custom profile properties in Klaviyo.
To create a new user in Klaviyo, you must pass either the userId, email, or phone properties in the identify call. If a user already exists, RudderStack updates the user profile with the latest values.
A sample identify call is shown below:
rudderanalytics.identify("1hKOmRA4el9Z", {
firstName: "Alex",
lastName: "Keener",
email: "alex@example.com",
phone: "+12 345 678 900",
title: "Owner",
organization: "Company",
zip: "100-0001",
Flagged: false,
properties: {
listId: "XUepkK",
subscribe: true,
consent: ["email"],
smsConsent: true,
},
})
Note that specifying consent and smsConsent in the event properties overrides the respective settings specified in the RudderStack dashboard.
Track
The track call lets you record the user actions along with any properties associated with them.
A sample track call is shown below:
rudderanalytics.track("Checked Out", {
Clicked_Rush_delivery_Button: true,
total_value: 2000,
Ordered: ["T-Shirt", "jacket"],
revenue: 2000,
})
In the above snippet, RudderStack captures the information related to the Checked Out event, along with the details of the event.
To associate a user with an event, you need to pass either their userId, email, or phone in the track call. A sample server-side track call along with the user information is as shown:
client.track({
userId: "1hKsmRA4el9Z",
event: "Item Purchased",
properties: {
revenue: 97.5,
products: [
{
productId: "pro1",
price: 32.5,
quantity: 3,
},
],
},
context: {
traits: {
email: "alex@example.com",
},
},
})
In the above snippet, RudderStack captures the information related to the Item Purchased event, along with its additional information in properties. Moreover, since this event is captured using a server-side SDK, RudderStack passes the user information in context along with a unique userId.
Note that:
- Use
context.traits to pass the information in your track or screen events in case you are using a server-side SDK that does not persist user context information. - To set a specific value to the
screen or track type event, you need to pass the event-related property in the properties field. Also, you can send revenue property in the track event and RudderStack will automatically map it to Klaviyo’s special property $value.
Ecommerce event mapping
RudderStack converts the following ecommerce events to the corresponding Klaviyo events:
| RudderStack event | Klaviyo event |
|---|
Product Viewed
Product Clicked | Viewed Product |
Product Added | Added to Cart |
Checkout Started | Started Checkout |
In addition to the above, RudderStack sends the following:
- Customer properties: Must contain either the
email or phone_number. RudderStack extracts these customer properties from traits/context.traits in the track call.
As mentioned above, you can send any number of key-value pairs as user traits and RudderStack updates them as custom profile properties in Klaviyo.
- Token: Public API key from the RudderStack dashboard.
Additionally, you can choose to send specific fields for each of the events covered in the following sections:
Product Viewed
RudderStack maps the Product Viewed event to Viewed Product and maps the following event properties:
| RudderStack property | Klaviyo property |
|---|
name | ProductName |
product_id | ProductID |
sku | SKU |
image_url | ImageURL |
url | URL |
brand | Brand |
price | Price |
compare_at_price | CompareAtPrice |
categories | Categories |
Product Added
RudderStack maps the Product Added event to Added to Cart and maps the following event properties:
| RudderStack property | Klaviyo property |
|---|
value | $value |
name | AddedItemProductName |
product_id | AddedItemProductID |
sku | AddedItemSKU |
image_url | AddedItemImageURL |
url | AddedItemURL |
price | AddedItemPrice |
quantity | AddedItemQuantity |
categories | AddedItemCategories |
item_names | ItemNames |
checkout_url | CheckoutURL |
items (deprecating soon)
products | Items |

properties.items will be deprecated soon.
Note that products/items can contain the following parameters:
| RudderStack parameters | Klaviyo parameters |
|---|
product_id | ProductID |
sku | SKU |
name | ProductName |
quantity | Quantity |
price | Price |
total | RowTotal |
url | URL |
image_url | ImageURL |
categories | ProductCategories |
Checkout Started
RudderStack maps the Checkout Started event name to Started Checkout and maps the following event properties:
| RudderStack Parameters | Klaviyo Parameters |
|---|
order_id | $event_id |
value | $value |
categories | Categories |
item_names | ItemNames |
items (deprecating soon)
products | Items |
checkout_url | CheckoutURL |

properties.items will be deprecated soon.
Note that products / items can contain the following parameters:
| RudderStack parameters | Klaviyo parameters |
|---|
product_id | ProductID |
sku | SKU |
name | ProductName |
quantity | Quantity |
price | Price |
total | RowTotal |
url | URL |
image_url | ImageURL |
categories | ProductCategories |
A sample track call containing the above ecommerce event parameters is shown below:
rudderanalytics.track("checkout started ", {
order_id: "1234",
value: 12.34,
categories: ["category1", "category2"],
checkout_url: "http://www.testcall.com",
item_names: ["item1", "item2"],
products: [{
product_id: "pId1",
sku: "sku1",
name: "item1",
url: "https://www.item1URL.com",
price: 1.0,
quantity: 1,
image_url: "https://www.item1Image.com,
categories: ["category1", "category2"],
row_total: 1.0
},
{
product_id: "pId2",
sku: "sku2",
name: "item2",
url: "https://www.item2URL.com",
price: 2.0,
quantity: 1,
image_url: "https://www.item2Image.com,
categories: ["category1", "category2"],
row_total: 2.0
},
],
});

It is not mandatory to specify the order_id as Klaviyo automatically assigns the timestamp to the event. However, if explicitly specified, it must be unique. Klaviyo automatically discards the events containing a duplicate order_id.
Page
The page call lets you record your website’s page views with any additional relevant information about the viewed page.
You can send the name and category information in the page event by enabling the Send Page As Track setting in the RudderStack dashboard. To associate the properties with the page view event, enable the Additional Page info setting as well.
A sample page call is shown below:
rudderanalytics.page("Cart", "Cart Viewed", {
path: "/cart",
referrer: "test.com",
search: "term",
title: "test_item",
url: "http://test.in",
})
