# How to create a Klaviyo Private API Key

Littledata's integration with **Klaviyo** requires a private API key in order to send **server-side** data.

If you choose the **automatic installation route** in the **Klaviyo** connection flow, you don't need to follow this guide because we will **automatically** create one for you.

If you choose the **manual installation route**, you will need to **manually introduce** the **Klaviyo** private API Key in the connection flow.

Here is how you can manually generate the **Klaviyo** private API key for the **Littledata** connection:

1. Go to your **Klaviyo Account** settings.
