Langfuse Trigger
AI-generatedSummary
Polls Langfuse for new traces, scores, or observations and emits matching records to start the workflow. The first scheduled poll establishes a baseline without emitting history; later polls use a time filter and IDs to avoid re-emitting records at the poll boundary.
Inputs
- Poll Times — Choose one or more polling schedules, such as every minute, hour, day, week, or month, every X minutes or hours, or a custom cron expression. Defaults to every minute.
- Event (required) — Select New Trace (default), New Score, or New Observation. The node requires Langfuse API credentials.
Output shape
A list of items, each containing one Langfuse record in its json field; returns no items when there are no new records.
A manual test fetch returns at most one recent record and does not update the polling cursor. Scheduled polling fetches at most 100 records per poll; records beyond that limit in one interval are not emitted. The initial scheduled poll only records a baseline and emits nothing.
