Headless CRM exposes CRM capabilities through APIs or tools without requiring a particular admin screen. In September 2026, Klaviyo announced access for external AI tools to read and write CRM data.
In the demo, a profile read from an external work tool passes a permission gate and returns a result. A write request requires a different approval.
Easy access raises the need for narrow permissions. Log which agent read which customer data and what it changed.
When to use
Use it to access customer context or CRM actions from an existing work tool.
