Channel Publisher

Content Syndication publishes Drupal content to external platforms from the node edit form, with queued delivery, retries, rate limiting and optional AI-generated captions. Facebook Pages are supported first.

Each destination is a plugin, so new platforms can be added without changing the core workflow. More destinations are planned, and they are not limited to social networks.

Features

• Pluggable PublisherPlatform plugins, one per destination.
• A "Publish to Channels" panel on the node form with an editable preview text and an optional scheduled time.
• Delivery through Drupal's queue and cron, with retries using exponential backoff (1, 2, 4, 8 and 16 minutes) and a maximum of 5 attempts.
• Per-account daily rate limiting, using each platform's own cap.
• A job history entity with revisions and Views integration, recording status, remote post ID and URL, attempts, and the last error.
• Optional AI-generated captions through the AI module's provider abstraction.
• An optional pre-publish AI-detection check, shown as a warning only. It never blocks publishing.
• OAuth tokens are stored with the Key module and never appear in exported configuration.

Facebook Page publishing (Graph API, text and image posts) is the only platform included today. Planned next are Instagram Business, Threads and Substack, along with ECA integration, automatic token refresh, and ready-made Views reports.

Post-Installation

1. Create a Key entity that holds the platform's access token.
2. Go to /admin/config/content/syndication/accounts and add an account, choosing the platform, the platform account ID and the Key.
3. Edit a node, open "Publish to Channels", select the account, and save.
4. Jobs are processed on cron, or on demand with drush queue:run content_syndication_publish.

Additional Requirements

• Drupal 11
• Key
• AI

Recommended modules/libraries

The AI Content Detector module enables the optional pre-publish detection check.

Instapost posts nodes to Instagram only and is no longer maintained. Content Syndication is built around a plugin API for multiple destinations, with queued delivery, retries and a job history.

Writing a platform plugin

Create a class with the #[PublisherPlatform] attribute that extends PublisherPlatformBase and implements validate(), transform(), publish(), status() and refreshToken(), plus the character limit, image support and daily post cap. See FacebookPagePublisher for a working example.
