FAQ

Questions about Make Voice Call.

What does the Make Voice Call action do in Vonage?

What inputs does Make Voice Call require?

Required: From (E.164), To (E.164), NCCO URL (returns call script). 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 Vonage 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 Make Voice Call support batch operations?

Yes. Run Make Voice Call inside a Loop node to process arrays. TinyCommand handles Vonage's rate limits automatically so you don't have to throttle manually.
