FAQ

Questions about Get Base Schema.

What does the Get Base Schema action do in Airtable?

Retrieves the table and field schema for an Airtable base, including field types and options. Used to dynamically populate column pickers and to validate field names before writes.

What inputs does Get Base Schema require?

Required: Base ID. Every input accepts a static value or a variable from any upstream node in your workflow.

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 Airtable 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 Get Base Schema support batch operations?

Yes. Run Get Base Schema inside a Loop node to process arrays. Tiny Command handles Airtable's rate limits automatically so you don't have to throttle manually.
