Difference between public and private API keys
Your public API key is also called your Site ID. This is a short alphanumeric value. This public key is a unique identifier for your Klaviyo account, and there is only one per account. It is safe to expose your public API key, as this key cannot be used to access data in your Klaviyo account.
Private API keys are used for reading data from Klaviyo and manipulating some sensitive objects such as lists. Treat private API keys like passwords kept in a safe place and never exposed to the public. A Klaviyo account can generate as many private API keys as needed.
