This guide will walk you through finding or creating those credentials within Klaviyo.

  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.
