FAQ

Questions about List Labels.

What does the List Labels action do in Gmail?

Lists all labels in your Gmail account (system labels like INBOX/UNREAD/IMPORTANT plus your custom ones). Used to populate a label picker.

What inputs does List Labels require?

List Labels 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 Gmail 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 Labels support batch operations?

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