This article provides a complete, practical walkthrough of the Http Respondtowebhook 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.

   📧 Automating Fastmail Masked Email Creation with n8n and Webhooks
   
   In today's digital environment, maintaining privacy online is more important than ever. Masked (or disposable) email addresses provide a secure way to protect your primary inbox while signing up for services or testing new platforms. Fastmail, the privacy-focused email service, offers an API for creating these masked email addresses—but integrating this feature into your workflow manually can be cumbersome.
   
   Thanks to n8n, a powerful open-source automation platform, you can now easily automate the process of creating a Fastmail masked email address using a simple webhook.
   
   In this article, we'll explore an n8n workflow that enables you to generate masked email addresses dynamically through a single HTTP request. Let’s break down how it works and how you can use it in your own projects.
   
   🚀 Why Use n8n for Creating Masked Emails?
   
   Using n8n gives you significant advantages:
   - No need to write custom backend code.
   - Instant deployment of automation.
   - Flexibility to scale and extend across many services.
   - Modern visual nodes that make creating workflows intuitive.
   
   🛠️ Workflow Overview: What This Template Does
   
   This n8n workflow is designed to generate a random masked email address via the Fastmail API using a POST request to a webhook. Here’s what happens step-by-step:
   
   1. 🔗 Webhook Trigger  
      The automation starts when a POST request is made to a unique webhook URL (e.g., https://yourdomain.com/webhook/createMaskedEmail). The request body can include optional JSON fields like "description" and "state".
   
      Example payload:
      ```json
      {
        "description": "Temporary sign-up email",
        "state": "pending"
      }
      ```
   
   2. 🔐 Fetch Session Info from Fastmail  
      Upon receiving the request, the workflow initiates an HTTP Request node to Fastmail's `/jmap/session` endpoint. This fetches necessary session details, including account IDs required for further API calls. The session request uses HTTP Header Authentication via an API token stored in your n8n credentials.
   
   3. 🧠 Extract and Prepare Fields  
      A Set node processes the webhook input to extract or default the core fields: `state` (default: "pending") and `description` (default: "Test via N8n"). These parameters are then used in generating the masked email.
   
   4. 🏗️ Create the Masked Email Address  
      This is where the magic happens. Using Fastmail’s JMAP API (at /jmap/api/), the workflow triggers a "MaskedEmail/set" method call to create a new masked email address tied to your Fastmail account. 
   
   5. 📤 Prepare Response  
      Once the masked email is created, another Set node extracts the new address along with its description and stores them in a clean format.
   
   6. ✅ Respond to Webhook  
      Finally, the automation replies to the original POST request caller (be it curl, an app shortcut, or another tool) with the newly created masked email address and its associated description.
   
   🎯 Example curl Request
   
   Here’s a quick example of how you can trigger this automation manually:
   
   ```bash
   curl -X POST https://your-n8n-instance/webhook/createMaskedEmail \
     -H 'Content-Type: application/json' \
     -d '{"state": "pending", "description": "my mega fancy masked email"}'
   ```
   
   And you’ll get a JSON response like:
   
   ```json
   {
     "email": "random12345@masked.example.com",
     "description": "my mega fancy masked email"
   }
   ```
   
   🔑 Requirements Before You Start
   
   To make use of this automation, ensure the following:
   - You have an n8n instance running and publicly accessible.
   - You’ve configured HTTP Header Authentication in n8n using your Fastmail API key.
   - Your Fastmail account has masking enabled (available in most paid plans).
   
   🧩 Extending the Workflow
   
   This workflow is fully extensible. Here are a few ideas:
   - Log masked emails into a database (e.g. Google Sheets, Airtable).
   - Auto-generate a QR code or add to a notes app.
   - Set up email forwarding or filters based on the generated address.
   
   📚 About the APIs Used
   
   The workflow makes use of the Fastmail REST APIs:
   - /jmap/session – Retrieves session and account information.
   - /jmap/api/ – JMAP-compliant endpoint for masked email creation using `MaskedEmail/set`.
   
   These APIs are well-documented in Fastmail’s developer portal: https://www.fastmail.com/dev/
   
   🎉 Conclusion
   
   Fastmail's masked email service is a fantastic privacy tool, and with this n8n workflow, integrating it into your digital life has never been easier. Whether you're building a privacy-first sign-up system, automating testing environments, or simply streamlining personal email hygiene, this workflow template gives you full control—without writing a single line of backend code.
   
   Now it’s your turn to experiment! Spin up your own n8n instance, plug in your Fastmail key, and start creating masked email addresses with a simple POST. Privacy made programmable!

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.
