FAQ

Questions about List Customers.

What does the List Customers action do in Wave?

Lists customers in Wave using the GraphQL API, scoped to a business ID. Use to populate a customer picker or to keep your CRM and Wave in sync.

What inputs does List Customers require?

List Customers 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 Wave 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 Customers support batch operations?

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