FAQ

Questions about LINE Broadcast.

What does the LINE Broadcast action do in LINE?

Sends a message to all followers of the connected LINE Official Account. Counts heavily against the plan's monthly message quota; use for newsletter-style fan-out.

What inputs does LINE Broadcast require?

Required: Messages array (JSON). 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 LINE 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 LINE Broadcast support batch operations?

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