ActionLINEUpdated September 2026
How do I broadcast to LINE followers?
Short answer: You can line broadcast in LINE by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the LINE LINE Broadcast action to a workflow, map its 1 input from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

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 run history shows the failed step with its input and the error message LINE returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does LINE Broadcast support batch operations?
Run LINE Broadcast inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within LINE's rate limits.
