Stream Feishu events in real time by establishing a WebSocket long connection that pushes subscribed updates as NDJSON, eliminating manual API polling. This approach captures messages, calendar changes, and approvals instantly for downstream agents.

Filter NDJSON event streams using the --filter flag to apply regex routing, sending specific Feishu chat events to designated downstream sinks. The --compact flag also flattens events and strips noise for cleaner message processing.

The best way to feed Feishu IM messages into automation is streaming im.message.receive_v1 events via WebSocket into NDJSON pipelines. This allows downstream agents to react to incoming chats and trigger actions like document updates instantly.

Yes, you can route Feishu calendar and approval notifications to different files using the --route flag. This applies regex filtering to the NDJSON event stream, directing specific event types to separate sinks for organized downstream processing.

Lark-cli event subscription supports read-only authentication when running WebSocket event streams. This ensures secure, limited-access ingestion of Feishu events into your NDJSON pipelines without granting broader modification permissions.

Use NDJSON format for Feishu WebSocket event streaming because it provides compact, line-delimited records ideal for continuous ingestion. This allows automation pipelines to process each event independently as it arrives over the long connection.
