  **Quick Summary**

  Complete Klaviyo integration requires three essential steps plus a critical follow-up for maximum value from your setup.

  * Generate a **Klaviyo Private API key** with Full Access in Klaviyo.
  * Connect Klaviyo in the **[Upstack dashboard](https://app.upstackdata.com/pixel/event-destinations)** using the Klaviyo Private API key.
  * Contact **[support@upstackdata.com](mailto:support@upstackdata.com)** to activate Upstack abandonment flows.
</Tip>

## Prerequisites

Before you start, you need:

* An active Upstack Data account ([sign up](https://app.upstackdata.com))
* Admin access to a **Klaviyo** account
* The ability to generate a **Klaviyo Private API key** with Full Access ([learn how to generate one](/guides/klaviyo/how-to-generate-klaviyo-api-key-for-upstack-data))

## Part 1: Generate a Klaviyo Private API key

* Sign in to **[Klaviyo](https://www.klaviyo.com/login)**.
* Click your **profile icon** in the bottom-left navigation.
* Go to **Settings → Account → API Keys**.
* Click the **Create Private API Key** button.
* Name the new key **`UpstackData`**.
* Under *Select Access Level*, choose **Full Access Key**.
* Click **Create**.
* Copy and save the Klaviyo Private API key immediately. It starts with `pk_` followed by alphanumeric characters (for example, `pk_aBcDeFgHiJkLmNoPqRsTuVwXyZ012345678`).

**`Success!`** `Klaviyo is now connected to Upstack Data.`

Need a more detailed walkthrough? See [How to configure the Klaviyo destination in Upstack Data](/guides/klaviyo/how-to-configure-klaviyo-destination-in-upstack-data).

## Part 3: Verify the connection

* In the Upstack dashboard, go to **Pixel → Event Destinations**.
* Confirm the **Klaviyo** destination is listed with a **Healthy** status.
* In Klaviyo, go to **Analytics → Metrics** and confirm Upstack-emitted events (for example, **Viewed Product - Upstackified**, **Added to Cart - Upstackified**, **Started Checkout - Upstackified**, **Active on Site - Upstackified**) begin appearing within a few minutes of live traffic.

<Warning>
  After completing the Klaviyo setup, contact **[support@upstackdata.com](mailto:support@upstackdata.com)** to request your Upstack abandonment flows be set up. These additive flows improve your abandonment capture by **up to 40% or more**.
