Drupal is a powerful open-source CMS used by enterprises and institutions, with JSON:API in core.
How Sorank connects: via Make.com (webhook bridge). Drupal 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 Drupal using a dedicated Make.com app. Sorank has no native Drupal connector, but the webhook plus Make route automates publishing end to end.
