1.1 Workflow description

Title: Monitor Shopify inventory & send low stock alerts to Slack
Workflow name: Monitor Shopify inventory & send low stock alerts to Slack

Inventory Low Stock Alerts

E-commerce Automation This n8n template automatically monitors your Shopify inventory levels and sends alerts when products fall below your defined threshold. Prevent stockouts and maintain sales revenue with proactive inventory management. Good to know

Default threshold is 10 units but easily customizable in the Code node Monitors all product variants individually Runs daily at 9 AM but schedule is fully adjustable Only sends alerts when action is needed (no empty notifications)

How it works

The schedule runs daily at 9 AM and connects to Shopify to download all products and variants. The workflow loops through every product and variant, checking inventory quantity for each item. It compares current stock against your threshold (default: 10 units) and identifies items below threshold. If any low stock items are found, it creates a comprehensive list and formats an alert message. The formatted report is sent to your Slack team so they can take immediate restocking action.

Set up instructions

Set up Shopify credentials in n8n: API Key, Password, Shop Subdomain, and Shared Secret The schedule trigger runs daily at 9 AM but feel free to adjust timing based on your business needs

Modify "lowStockThreshold" variable in the Code node (default is set to 10 units) Set up Slack credentials and create a dedicated #inventory channel for alerts Ensure your Shopify products have inventory tracking enabled in product settings

Test the workflow manually to verify it correctly identifies low-stock items

What team sees:

"🚨 Low Stock Alert!

T-Shirt Blue (Medium): 3 left Coffee Mug (White): 7 left Phone Case (Black): 2 left"

Business logic: Stock above threshold equals no alert. Stock at or below threshold equals alert sent. Stock at zero equals out of stock which is critical.

Customising this workflow

Add email alerts for critical out-of-stock items Set different thresholds for different product categories Include supplier contact information in alerts

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.
