Matrix API Entity

Bidirectional sync between Drupal content entities and Matrix room threads. Nodes and comments mirror to Matrix; replies in Matrix create Drupal content.

Features

• Maintains a mapping table between Drupal entity IDs and Matrix event IDs, so each entity knows which Matrix message it corresponds to and vice versa
• Outbound sync: when a node or comment is created, posts it to a configured Matrix room and stores the returned event ID
• Inbound sync: when a Matrix thread reply arrives, creates the corresponding Drupal comment (or other entity) attributed to the correct node
• InboundSyncService and OutboundSyncService with clean PHP APIs for custom integrations
• EventIdIndex for efficient bidirectional lookups
• ECA Plugins for retrieving mapped IDs, adding to the map

Post-Installation

Configure the entity types and Matrix rooms to sync on the module settings page. The module builds on top of ECA — install an ECA model (such as the one included in matrix_api_demo from matrix_recipes) to wire up the sync logic without custom code, or use the services directly in your own module.

Additional Requirements

matrix_api. ECA is recommended for configuration-driven sync; the services work standalone for code-driven use.
