A Shopify app for LINE
Send LINE messages from Shopify Flow
JustFlow for LINE is a Shopify app that sends LINE messages from Shopify Flow workflows and campaigns.
Customers link their LINE account with LINE Login from the order confirmation page, the order status page, a theme block, or their customer account page. You can send linked customers text messages and Flex messages built in a visual editor. You can also have AI tools such as Claude Code create campaign drafts.
What JustFlow for LINE does
Send LINE from Flow
Add one action to a Shopify Flow workflow to send text or Flex messages to customers who have linked LINE.
Send from your own LINE Official Account
Messages arrive from the merchant's own LINE Official Account.
No webhook changes
The app does not change your LINE Official Account's webhook settings, so you can use it alongside other tools that already use the webhook.
AI integration (MCP)
Let AI draft your campaigns
Ask the AI you already use to "create a campaign like this", and a draft appears in JustFlow for LINE. Messages are sent only after the merchant reviews them.
- Connect from AI tools that support MCP, such as Claude Code, Codex and Cursor
- The AI checks your templates and recipients and builds a Flex message draft
