How do we personalize decoupled experiences in Sitefinity CMS?

Audience rules and variants are defined in Progress® Sitefinity® CMS and applied at render time via REST or GraphQL, so personalization works regardless of the front‑end framework.

When supporting secure portal scenarios in a decoupled front-end, the front-ends integrate authentication/authorization, while Sitefinity CMS enforces roles, permissions and audience rules on content retrieved through APIs.
