# Preview Custom Session Claims

When customizing session tokens, you can now preview the resulting claims before saving your changes.

Select a user to generate claims based on the current template. This lets you verify that custom claims, template expressions, and organization data produce exactly the claims you expect.

Previously, saving a template then inspecting a real session token was required to check the template is correct. Preview lets you ensure expected behavior before impacting real users.
