FAQ

Questions about List Avatars.

What does the List Avatars action do in Synthesia?

Returns the avatars available in your Synthesia workspace, including stock avatars and any custom personal avatars. Use it to render an avatar picker before generating.

What inputs does List Avatars require?

List Avatars 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 Synthesia 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 Avatars support batch operations?

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