Overview

To authenticate with Klaviyo, you need one key piece of information:
  1. API Key - Your Klaviyo private key.
This guide will walk you through finding or creating those credentials within Klaviyo.

​
Prerequisites:

  • You must set up an account with Klaviyo.

​
Step 1: Finding Your Klaviyo API Key

  1. Log into your Klaviyo account and navigate to your account’s Settings page and select API keys.
  2. Under the Private API Keys section, select Create Private API Key.
  3. Provide a name for your private key and add any of the following scopes:
    • Custom Key: Allows you to decide how much access to give the third party.
    • Read-Only Key: Only allows third parties to view all data associated with the endpoint.
    • Full Access Key: Allows third parties to create, delete, or make changes to anything associated with that endpoint.
Important: For your account’s security, your private API keys should never be used with Client endpoints, exposed in client-side code, or made accessible from public repositories.
  1. When you have finished setting your key’s scopes, select Create.
  2. Securely store your private key. This key is only visible one time.
