FAQ

Questions about List Calendars.

What does the List Calendars action do in Google Calendar?

Lists all calendars available to the authenticated user (primary, secondary, subscribed) with access role. Used to populate a calendar picker.

What inputs does List Calendars require?

List Calendars has no required inputs. Sensible defaults are applied if you leave fields blank.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Google Calendar returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does List Calendars support batch operations?

Yes. Run List Calendars inside a Loop node to process arrays. Tiny Command handles Google Calendar's rate limits automatically so you don't have to throttle manually.
