Trigger flow on new YouTube comments

Polls one or more video IDs for comments newer than the last interval (default PT30M). Uses an OAuth2 bearer token, honors YouTube's 1–100 maxResults limit (default 20), and fetches comments ordered by time or relevance.

Defaulttrue

A condition that determines whether the trigger should run.

A Pebble expression evaluated at trigger time. The trigger fires only when the expression evaluates to a truthy value (true, a non-empty string, a non-zero number). Use this to gate trigger execution on dynamic runtime values such as execution labels, flow variables, or environment conditions.
