FAQ

Questions about Send Text Message.

What does the Send Text Message action do in WhatsApp Business?

Sends a free-form text message to a WhatsApp customer; only allowed within the 24-hour customer service window opened by their most recent inbound message. Outside that window, use Send Template Message instead.

What inputs does Send Text Message require?

Required: Recipient phone (E.164), Body. 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 WhatsApp Business 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 Text Message support batch operations?

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