Use this interactive demo to learn how to locate your Klaviyo Public API Key and account ID.

Quick summary

Your Klaviyo Account ID is the same as your Public API Key, found under Settings > API Keys in your Klaviyo dashboard. This guide walks you through every click needed to locate and copy your account ID for use in third-party integrations.

Steps

Access your profile by clicking your account name in the Klaviyo dashboard to open account and integration settings.
Navigate to the Settings area where you can configure API connections and integration options.
Open the API Keys section to view and manage the secure connection points for your integrations.
Locate the Public API Key / Site ID field on the API Keys page.
Copy the value shown — your Public API Key is your Klaviyo Account ID.

📌 Why this matters

Knowing your Klaviyo Account ID is essential for connecting Klaviyo to third-party tools, ad platforms, and custom integrations. The Account ID — also called the Public API Key or Site ID — is the unique identifier that authenticates your Klaviyo account with external services. Without it, integrations such as Google Audiences sync, e-commerce plugins, and marketing automation workflows cannot be established. Finding it quickly reduces setup friction and gets your data-driven campaigns running faster.
