1.1 Workflow description

Title: Read palm lines and send AI reports via LINE, Gemini, Gmail and Calendar
Workflow name: Read palm lines and send AI reports via LINE, Gemini, Gmail and Calendar

Template description (paste this into the n8n Creator Dashboard)

Who is this for

This workflow is for anyone who wants to offer a fun, automated palm reading experience through LINE — Japan's dominant messaging app with over 90 million active users. It suits indie developers, wellness creators, fortune-telling services, or anyone curious about combining AI vision with multi-channel automation.

What this workflow does

When a user sends a photo of their palm via LINE, the workflow springs into action across five tools:

LINE Messaging API receives the image via webhook
Google Gemini analyzes the palm and produces three outputs: a short LINE-ready summary (under 100 characters), a full reading covering the life line, heart line, head line, and fate line, and three lucky day suggestions with reasons
LINE reply sends the short summary back to the user instantly
Gmail delivers a formatted HTML report with the complete reading to a specified address
Google Calendar registers the three lucky days as calendar events so the user never forgets them

Non-image messages (text, stickers) are caught early and trigger a friendly prompt asking the user to send a palm photo instead.

How to set up

Open the Set config variables node and fill in your LINE_CHANNEL_ACCESS_TOKEN, GMAIL_FROM, GMAIL_TO, and GOOGLE_CALENDAR_ID
Connect your Google Gemini API credential to the Google Gemini Chat Model node
Connect your Gmail OAuth2 credential to the Gmail node
Connect your Google Calendar OAuth2 credential to the Calendar node
Activate the workflow and copy the webhook URL
Paste the webhook URL into your LINE Developer Console under the Messaging API channel settings

Requirements

LINE Developer account and a Messaging API channel (free)
Google Gemini API key (free tier available at Google AI Studio)
Gmail account with OAuth2 set up in n8n
Google Calendar with OAuth2 set up in n8n

How to customize

Change the reading language: edit the prompt in the Analyze palm lines with Gemini node — swap English for Japanese, Spanish, or any language Gemini supports
Adjust the report destination: update GMAIL_TO in the config node to send the report to the user's own address (you could collect it via a prior LINE conversation)
Change lucky day timing: the Calendar node currently schedules events starting 7 days from now — adjust the $now.plus() expression to fit your use case
Extend the AI prompt: add astrology, tarot, or numerology sections to the Gemini prompt for a richer reading experience

Predict airport queue wait times and email alerts with OpenAI and SendGrid

## Quick Overview This workflow accepts traveler flight details via webhook or runs every 5 minutes, predicts airport queue wait times with a custom JavaScript model, generates an alert message using OpenAI, emails the traveler via SendGrid, and logs the prediction to Google Sheets. ## How it works 1. Receives a POST request to a webhook with traveler/flight details or runs on a 5-minute schedule. 2. Normalizes the incoming data into a consistent context (flight, airport/terminal, traveler contact details, and live queue inputs). 3. Waits briefly to throttle processing, then calculates predicted security, immigration, and boarding wait times plus risk flags and an optimal arrival time. 4. Sends the prediction to OpenAI to generate a short, traveler-friendly alert message. 5. Formats the final alert payload (alert level, email subject/body) and prepares a row for tracking. 6. Sends the alert email through the SendGrid Mail Send API and appends the prediction record to a Google Sheets tab. ## Setup 1. Configure the webhook URL in the system that submits traveler requests (POST to `/airport-queue-check`) or enable the schedule trigger for proactive runs. 2. Add OpenAI credentials and select the chat model used to generate the traveler message. 3. Add Google Sheets OAuth2 credentials and replace `YOUR_SHEET_ID` and the target range (for example, `Predictions!A1:append`) in the Google Sheets request URL. 4. Add your SendGrid API key by replacing `YOUR_SENDGRID_API_KEY` in the Authorization header, and update the sender/recipient fields (including ensuring `travelerEmail` is provided by the trigger payload).

Send transactional SMS with the OVHcloud SMS API

## Quick overview This workflow manually triggers an HTTP request to the OVHcloud SMS API, signing it with your OVH application credentials to send a transactional SMS to a specified phone number. ## How it works 1. Runs when you manually execute the workflow. 2. Sets the OVHcloud API credentials, SMS service name, sender, and target API region. 3. Defines the SMS recipient number and message text to send. 4. Generates the OVHcloud request URL, JSON body, timestamp, and SHA1-based X-Ovh-Signature headers. 5. Sends a POST request to the OVHcloud endpoint `/sms/{serviceName}/jobs` to create an SMS sending job. ## Setup 1. Create OVHcloud API application credentials (Application Key and Application Secret) and a Consumer Key with SMS permissions. 2. Replace the placeholder values for `APPLICATION_KEY`, `APPLICATION_SECRET`, `CONSUMER_KEY`, `SMS_SERVICE_NAME`, `SMS_SENDER`, and `OVH_REGION`. 3. Update the `receiver` (E.164 format) and `message` fields with the SMS details you want to send, and ensure your OVHcloud SMS account has available credits. ## Requirements - OVH account - SMS credits (API account)

Tutor English chat messages using OpenRouter with Postgres memory and log to Supabase

## Quick overview This workflow receives English practice messages via a webhook, uses an OpenRouter chat model with Postgres-backed conversation memory to generate tutoring feedback, logs the exchange to Supabase, and returns the tutor’s reply as a JSON response. ## How it works 1. Receives a POST webhook request containing a `user_id` and `message`. 2. Extracts and standardizes the incoming fields so the workflow has clean `user_id` and `message` values. 3. Sends the message to an AI English tutor powered by OpenRouter, using Postgres chat memory keyed by `user_id` to maintain per-student context. 4. Logs the tutor output to a Supabase `conversations` table along with the user identifier and original message. 5. Returns a JSON response to the caller containing the tutor’s reply. ## Setup 1. Add an OpenRouter API credential and (optionally) choose a different model in the OpenRouter chat model configuration. 2. Add Postgres credentials and ensure the database is reachable from n8n so chat memory can persist sessions by `user_id`. 3. Add Supabase credentials and create a `conversations` table, then confirm the mapped columns (`user_id`, `role`, `message`) match your schema. 4. Copy the webhook URL from n8n and configure your app to POST a JSON body with `user_id` and `message` to that endpoint.
