Plasmic is a visual builder with a light CMS exposing a REST Write API.
How Sorank connects: via Make.com (webhook bridge). Plasmic exposes an API with an endpoint to create blog posts, so each article Sorank generates is sent to a Make.com scenario through a webhook, and Make publishes it to Plasmic using Make.com's generic HTTP module. Sorank has no native Plasmic connector, but the webhook plus Make route automates publishing end to end.
