External Entities Media Synchronizer

Automatically creates and synchronizes Drupal media entities from remote data exposed through the External Entities module. Each enabled external entity type gets its own media type, populated via a Drush command — no custom code required.

Features

• Automatically creates a dedicated media type for each external entity type when synchronization is enabled.
• Drush command to create, update, and clean up media entities in bulk. Supports filtering by entity type or by specific remote IDs.
• Configurable behavior when a remote entity disappears: do nothing, unpublish, or delete the corresponding media.
• Each media entity is only an entity reference to the external entity.
• Downloads and caches remote thumbnail images locally from a configurable Drupal field (e.g. field_image_url).
• One-click batch deletion of all media entities linked to an external entity type, with confirmation step.
