Sanity is a widely used headless CMS whose HTTP Mutation API creates documents.

How Sorank connects: via Make.com (webhook bridge). Sanity 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 Sanity using Make.com's generic HTTP module. Sorank has no native Sanity connector, but the webhook plus Make route automates publishing end to end.
