This article provides a complete, practical walkthrough of the Code Webhook Automation Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Automated Inventory Monitoring for Shopify with n8n and Discord
   
   Inventory management is critical in eCommerce. Failing to track stock levels can result in missed sales, unhappy customers, and operational inefficiencies. Fortunately, with n8n — a powerful open-source workflow automation tool — store owners can automate how inventory changes are tracked and communicated.
   
   In this article, we explore a fully automated n8n workflow that watches for two key stock events in Shopify: when inventory is low, and when a product is completely out of stock. When such events occur, the system sends a richly formatted alert to specific Discord channels, allowing store managers and support teams to act immediately.
   
   Let’s break down how this workflow is built and how it works.
   
   Overview of the Workflow
   
   The main objective of this n8n workflow is to receive real-time inventory updates from a Shopify store, evaluate stock quantity, and send a Discord alert when stock is either low or completely depleted.
   
   This setup is perfect for eCommerce teams that want:
   - Near-instant alerts for critical stock levels.
   - Detailed product information in alerts (e.g., titles, images, SKU variants).
   - Platform-agnostic integration that can later be expanded beyond Discord.
   
   Key Triggers and Workflow Steps
   
   1. Webhook Listener from Shopify
   
   The automation begins with a Webhook node configured to listen to the “Inventory Level Update” event from Shopify. For this setup to work, you need to register this webhook in your Shopify admin and point it to the n8n webhook URL generated by this node.
   
   Any time an inventory item is updated, Shopify sends a POST request, which triggers the workflow.
   
   2. Code Node: Inventory Evaluation
   
   Next, a custom Code node processes the webhook payload. This JavaScript snippet pulls out two key values:
   - available — the current number of items in stock
   - inventory_item_id — the unique identifier for the inventory item
   
   It also sets flags:
   - low_inventory (true if inventory is more than 0 but less than 4)
   - out_of_stock (true if inventory is 0)
   
   These boolean values determine how the workflow branches next.
   
   3. Conditional Routing
   
   The workflow uses two “IF” nodes to evaluate the inventory condition.
   
   - Low Inventory IF Node: This triggers if the product has fewer than 4 items but is not yet out of stock.
   - Out of Stock IF Node: This triggers if the product has hit zero inventory.
   
   4. Shopify GraphQL Data Retrieval
   
   Either outcome then leads to a GraphQL query against the Shopify Admin API. This step fetches rich product details, including:
   - Product and variant title
   - Current inventory quantity
   - Product image URL (first image only)
   
   This is essential for creating visually informative Discord alert messages.
   
   5. Discord Notification
   
   The final step involves sending an alert message to Discord via the Discord Bot API.
   
   - If the item is low in stock, the alert is sent to “Channel A” with a yellow-highlighted embed containing product information.
   - If the item is out of stock, another message is sent to “Channel B” using a red-colored embed.
   
   Each alert includes:
   - Product title and variant
   - Number of items remaining (0 or low)
   - Thumbnail of the product image
   - Alert message detailing the stock condition
   
   Benefits of This Workflow
   
   This n8n automation tackles a common eCommerce pain point — poor visibility into inventory health. With this solution, businesses get:
   
   - Real-time inventory alerts
   - Fewer missed sales due to out-of-stock products
   - Platform flexibility (easily adapted to Slack, Teams, email, etc.)
   - Visual-rich notifications that provide immediate context
   
   Adaptability & Customization
   
   - Thresholds: You can adjust the number used to define “low stock” by updating the code in the Code node.
   - Notification Channels: Although this demo uses Discord, any other API-capable platform can be substituted.
   - Product Details: Modify the GraphQL query to retrieve more or fewer fields as needed.
   
   Important Setup Notes
   
   - Shopify Authentication: You will need to authorize the GraphQL requests to Shopify using appropriate API credentials via header authentication.
   - n8n Hosting: This workflow assumes self-hosted or cloud-hosted n8n with public accessibility to receive Shopify webhook payloads.
   - Replace Placeholder URLs: Ensure you replace https://store.myshopify.com with your actual Shopify store’s endpoint.
   
   Final Thoughts
   
   By pairing Shopify’s robust API with n8n’s visual automation editor and Discord’s messaging platform, this workflow provides a reliable, hands-off way to watch inventory levels. It empowers eCommerce teams to respond faster and more proactively to stock-related issues — driving better customer experience and sales outcomes.
   
   If you’re looking to minimize manual inventory checks and maximize automation, this n8n workflow is an excellent place to start.
   
   

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
