What inputs does Send SMS require?

Can I use dynamic inputs from earlier workflow nodes?

What happens if Twilio 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 Send SMS support batch operations?
