# Klaviyo
## Overview
Integrate Novel's wallet passes into your Klaviyo emails. With this integration, you can embed personalized wallet pass URLs in your emails that enable a one-click install. Your customer's don't need to login.
To get started, you'll want to get your private API key from the Klaviyo app. You can find it under: **Settings -> API Keys -> Create Private API Key -> Full Access Key**
In Novel, navigate to **Integrations -> Klaviyo.** Enter your API Key, click save, and you're done!
Novel App
You'll see the following custom attributes being added to Klaviyo profiles that are Shopify customers. Use the **$NovelEmailPassLink** attribute for emails and the **$NovelSmSPassLink** for SMS outreach.
{% hint style="info" %}
It may take some time to update your profiles in Klaviyo, depending on the number of customers you have.
{% endhint %}
Klaviyo Custom Attributes
To use these attributes in emails, insert the following as the image URL. Don't forget to replace the \[yourstorefront] with the URL in your [Novel pass install link. ](/start-guide/distribute-your-pass.md)
We recommend that you use the *add to wallet* images in the [Novel brand kit](https://www.figma.com/file/5u5yQM726XWS0WurrX1Hcw/Novel-Brand-Kit-\(Community\)?type=design\&node-id=0%3A1\&mode=design\&t=ZNsU9QGKuJtPLptM-1) when creating your email and using the below as the URL.
```
{{person|lookup:'$NovelEmailPassLink'|default:'https://[yourstorefront].novel.com/email'}}
```
For email design help, refer to the Novel brand kit Figma below.

### Store Credit Balance Attribute
Novel can sync a customer’s store credit balance into Klaviyo as a profile attribute.
Attribute:
```
$NovelStoreCreditBalance
```
You can use this in Klaviyo emails and flows to dynamically display each customer’s balance.
Example:
```
You currently have ${{ person|lookup:'$NovelStoreCreditBalance' }} in store credit.
```
Common use cases:
* Monthly rewards emails
* VIP / loyalty updates
* Store credit reminders
* Winback campaigns
If you do not see this attribute in Klaviyo, contact Novel support to enable store credit syncing.
