FAQ

Questions about Search Channels.

What does the Search Channels action do in Slack?

Retrieves channels from Slack matching a search query. Used as a faster alternative to listing every channel for picker UIs.

What inputs does Search Channels require?

Search Channels 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 Slack 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 Search Channels support batch operations?

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