FAQ

Questions about List Tables.

What does the List Tables action do in Supabase?

Lists all tables in a Supabase database (from the public schema) with their column metadata. Used to dynamically populate table pickers and column dropdowns.

What inputs does List Tables require?

List Tables 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 Supabase 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 Tables support batch operations?

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