# Klaviyo Enable the integration to send customer email and additional field details to Klaviyo. **Note:** Klaviyo will send an email to the customer asking them to confirm their subscription. This is in addition to the registration confirmation email sent by the app after successful registration. *** ## Finding the **Private Key** in Klaviyo 1. Log in to your Klaviyo account. 2. Navigate to **Account**. 3. Go to **Settings**. 4. Select **API Keys**. 5. Generate a new **Private Key**. Ensure it is a **Custom Key** with **Full Access** to Lists, Profiles, and Subscriptions. *** ## Setting Up the App with the Private Key 1. Go to the **Shopify Apps Admin**. 2. Navigate to **My Product Registration**. 3. Go to **Settings > Integrations**. 4. Under **Klaviyo Integration**, enter the **Private Key**. 5. Scroll to the bottom and click **Save Settings**. Next, go to the **Form's Settings** and select the Klaviyo list where you want the data to be sent. *** ## **Checkbox for Consent** Once the integration is set up, a new checkbox will be added to the form, asking customers for permission to send their data to third-party integrations. You can customize the checkbox text in the app admin under **Settings > Languages > Send Data To Third Party**. Update the text to match your requirements. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
