How it works

Connect LINE and Slack in five steps.

No code, no glue, no half-day setup. Each step is one click.

1
Connect
Authorize LINE and Slack
Open TinyCommand, authorize LINE and Slack once each. Both connections are available to every workflow on your account.
2
Trigger
Pick a LINE trigger
Drop the LINE → New event trigger onto the canvas. TinyCommand auto-registers the webhook.
POST /v1/webhooks/line.event
3
Transform
Add a filter or AI step
Optionally add a Filter node ("subject contains URGENT") or an AI step ("classify intent") between trigger and action.
4
Action
Add the Slack action
Drop the Slack → Add Reaction action below it. Map fields from the LINE payload into the Slack inputs.
slack.add-reaction
5
Publish
Publish and forget
Hit Publish. TinyCommand runs it in production from second one. Watch the run-log fill up.

FAQ

Questions about LINE + Slack.

How long does it take to connect LINE and Slack on TinyCommand?

Under two minutes. Authorize LINE and Slack once each, drop the LINE trigger and Slack action onto a workflow canvas, map a couple of fields, and publish. No code, no glue.

Is the LINE ↔ Slack integration real-time?

Yes. Both LINE and Slack expose webhooks, so events from one fire workflows in the other within seconds rather than on a polling interval.

Can I filter or transform data between LINE and Slack?

Yes. Add a Filter node to only pass through matching events, a Switch node to branch by value, or an AI / Code node to transform payloads before they hit Slack.

What LINE events can trigger a Slack workflow?

Use TinyCommand's universal Webhook trigger to receive LINE events, then run any of the 45 Slack actions downstream.

Do I need a paid plan to use LINE with Slack?

No. There's a free tier that covers most LINE+Slack use cases without a credit card. Paid plans unlock higher run volumes and team features when you outgrow it.

What if I want Slack → LINE instead?

Build it the same way, in reverse. There's a dedicated /integrations/slack/with/line page with the reverse-direction triggers and actions.
