Http Schedule Create Webhook – Web Scraping & Data Extraction | Complete n8n Webhook Guide (Intermediate)
This article provides a complete, practical walkthrough of the Http Schedule Create 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.

Title: How to Relay Public Webhooks to Your Local n8n Workflow Using webhook.site Meta Description: Learn how to configure an n8n workflow that uses webhook.site and a key-value store to relay public webhook POST requests into a locally running n8n instance. Ideal for local development and debugging. Keywords: n8n, n8n workflow, webhook.site, n8n automation, public webhook relay, webhook proxy, local development, n8n Webhook Trigger, key-value store, n8n storage, automation, no-code Third-Party APIs Used: - Webhook.site API (https://webhook.site) Article: Relaying Public Webhooks to Your Local n8n Workflow Using webhook.site If you've ever faced the challenge of testing webhooks from external services while developing locally, you know it can be tricky. Services like Stripe, GitHub, or custom APIs send webhook payloads to publicly accessible URLs—something your localhost just doesn’t offer by default. Enter this n8n workflow, which bridges that gap using webhook.site as a temporary external endpoint. This clever setup polls webhook.site for new incoming POST requests, filters them, and forwards them to a running n8n instance on your local machine. It uses a key-value store for persistent state between intervals and provides a clean, no-code/low-code approach to solving an age-old developer dilemma. Let’s explore how it works. Overview of the Workflow This workflow orchestrates five key stages: 1. Scheduling Polls 2. Retrieving & Storing webhook.site Auth Key 3. Polling for New Requests 4. Filtering & Relaying Only Unprocessed POSTs 5. Sending the Data to Your Local n8n Workflow Step 1: Schedule Trigger The workflow is initiated by a Schedule Trigger Node configured to run every 10 seconds. This polling interval is adjustable depending on how often you expect new data. Step 2: Retrieve or Create an Auth Token webhook.site provides unique temporary endpoints using what it calls an "auth token" (UUID). The workflow first checks if a token already exists in persistent storage using a key-value store (@horka.tv/n8n-nodes-storage-kv). If not, it requests a new token from webhook.site via a POST request and stores that value for reuse in future polls. Step 3: Get Latest Requests Once the auth token is available, the workflow sends a GET request to https://webhook.site/token/{uuid}/requests to retrieve all past incoming requests that token has collected. That includes any webhook data forwarded from external services. Step 4: Filter Unprocessed POST Requests Here's where things get smart. Using a JavaScript code node ("Unprocessed Requests"), the workflow filters out any webhook request that: - Has already been processed (compared using timestamp) - Is not a POST request This ensures that the workflow doesn't forward duplicate or irrelevant data. The node transforms date strings into Unix timestamps and evaluates whether the request came after the last processed time (also stored in key-value storage). Step 5: Send Request to Local n8n Workflow Any newly detected, unprocessed POST requests are sent to a predefined local URL set in the "Local Webhook Address" node (e.g., http://localhost:5678/webhook/xyz). The workflow uses a raw HTTP POST to forward the original request body as-is. Finally, the system updates the "last processed time" in persistent storage, so that next time it polls, it only considers newer requests. Use Cases - Develop and test Stripe, GitHub, or 3rd-party service webhooks without deploying your n8n workflows publicly. - Act as a public-to-local relay in development environments. - Build debugging tools that simulate how your local workflows respond to production webhooks. How to Set It Up 1. Install the key-value storage community node: @horka.tv/n8n-nodes-storage-kv. 2. Set your local listening endpoint in the “Local Webhook Address” node. 3. Activate the workflow and wait for the first polling interval. 4. Grab the auth token shown in the “Get Latest Requests” input. 5. Simulate a webhook: curl -X POST -H "Content-Type: application/json" -d '{"foo":"bar"}' https://webhook.site/[auth_token] 6. Watch your downstream local n8n webhook receive the payload. Caveats - Only POST requests with JSON/form data are supported out-of-the-box. - To relay GET or URL-encoded requests or raw text payloads, you’ll need to customize the “Unprocessed Requests” and “POST to n8n” nodes to suit your needs. - The public webhook relies on webhook.site, which is a third-party tool great for prototyping but not ideal for production. Conclusion This n8n workflow showcases the power of no-code/low-code automation for developers. By combining webhook.site with n8n and a smart key-value store, you can easily debug and test public-facing webhooks even when your workflow lives purely on localhost. It's a powerful tool that saves time, reduces complexity, and gives you seamless visibility into every incoming request before it ever touches your real systems. Feel free to fork, modify, and enhance this setup for your own workflow packages or debugging needs.
- Set credentials for each API node (keys, OAuth) in Credentials.
- Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
- 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.
