FAQ

Questions about Send SMS.

What does the Send SMS action do in Telnyx?

Sends a text message from a Telnyx number (or messaging profile) to a destination number. US/Canada destinations require 10DLC registration to avoid carrier filtering.

What inputs does Send SMS require?

Required: From (E.164), To (E.164), Text. 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 Telnyx 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?

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