Line Notify Service: Send Messages, Images & Stickers Automatically

This workflow automates manual notification processes, replacing time-consuming manual messaging with instant Line notifications for alerts or updates. It uses Webhook (n8n-nodes-base.webhook) to receive requests, Set (n8n-nodes-base.set) to validate and extract inputs like message content and stickers, IF (n8n-nodes-base.if) to check validity, and another Set to format messages with timestamps and types (e.g., info, alert). Line (n8n-nodes-base.line) sends notifications with optional images/stickers, IF checks delivery, Function (n8n-nodes-base.function) processes results, and RespondToWebhook (n8n-nodes-base.respondToWebhook) delivers success/error responses. This benefits customer support, marketing, or ops teams sending 100-500 daily notifications, enabling real-time updates like order confirmations or alerts, improving engagement in regions where Line is popular (e.g., Asia).\n\nThis workflow saves 3-5 hours weekly on manual messaging for teams, ideal for small to medium businesses (10-100 employees) in e-commerce, logistics, or retail. Requires Line Notify (free) and n8n (free self-hosted or $20/month cloud). Scalable to thousands of notifications, limited by Line API rate limits (1000/day free tier). No additional storage needed.\n\nThis workflow requires n8n from n8n.io (self-hosted) or cloud.n8n.io. For Line Notify: Register at notify-bot. line.me, get OAuth2 token, add to LineNotifyOAuth2Api credentials in n8n. Configure the Line node with a token. Webhook auto-generates URL on activation; set path to 'line-notification'. Ensure that the set nodes validate the message content and operation type.\n\nThis workflow is tested by POSTing JSON (e.g., {'message': 'Order shipped!', 'type': 'info'}) to the webhook URL, verifying Line delivery. Common errors: Invalid token (regenerate at Line Notify), rate limits (monitor usage, request higher quota). Deploy by activating the workflow. Monitor n8n logs for delivery failures; optimize by caching frequent messages in the Set node. Review Line API updates quarterly."
