FAQ
Questions about List Outline Collections.
What does the List Outline Collections action do in Outline?
Returns every collection (top-level docs container) the user can see. Useful for resolving collection IDs at workflow setup.
What inputs does List Outline Collections require?
List Outline Collections 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 Outline 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 Outline Collections support batch operations?
Yes. Run List Outline Collections inside a Loop node to process arrays. Tiny Command handles Outline's rate limits automatically so you don't have to throttle manually.
