This article provides a complete, practical walkthrough of the Manual Stickynote Automation Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Expert setup in 2-4 hours. One‑time purchase: €149.

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.

   How to Automate PDF Merging in n8n Using ConvertAPI
   
   In today’s digital workflows, handling documents efficiently is crucial — especially when it comes to merging PDFs for reporting, archiving, or sharing information. Manually downloading and combining PDFs can be tedious and error-prone. Luckily, with n8n — a robust, open-source workflow automation platform — such tasks can be streamlined effortlessly. This article walks you through how to create a simple yet powerful workflow in n8n that automatically downloads two PDF files, merges them using ConvertAPI, and writes the final document to your local storage.
   
   🧠 Workflow Overview
   
   Here’s a quick breakdown of what this n8n workflow does:
   
   - Uses a manual trigger to start the workflow.
   - Downloads two remote PDF files.
   - Sends both files to the ConvertAPI merge endpoint.
   - Receives the merged PDF.
   - Writes the merged document to a local file (document.pdf).
   
   Let’s dive into how each step works.
   
   🔁 Step 1: Start with Manual Trigger
   
   The workflow begins with the "When clicking ‘Test workflow’" node. This manual trigger allows testing the workflow directly from the n8n editor. It’s ideal during development or for processes that don’t require scheduling or external event triggers.
   
   🧾 Step 2: Download PDFs from Remote URLs
   
   The workflow then proceeds to two HTTP Request nodes:
   
   - “Download first remote PDF File” — Retrieves a sample file from: https://cdn.convertapi.com/public/files/demo.pdf
   - “Download second PDF File” — Retrieves a second file from: https://cdn.convertapi.com/public/files/demo2.pdf
   
   Both nodes use the HTTP Request node configured to receive a file response and store the binary data as data1 and data2 respectively. These outputs are essential for the next step — merging.
   
   🚀 Step 3: Merge Files via ConvertAPI
   
   The "PDF merge API HTTP Request" node bridges the downloaded files with the ConvertAPI’s PDF merging endpoint: https://v2.convertapi.com/convert/pdf/to/merge
   
   Key configurations include:
   
   - HTTP Method: POST
   - Content-Type: multipart/form-data
   - Body Parameters: files[0] and files[1], set to data1 and data2, respectively
   - Authentication: Query parameter-based, using your ConvertAPI secret token
   - Header: Accept: application/octet-stream to indicate that we are expecting a binary file in return
   
   This node sends both downloaded files to ConvertAPI, which processes and returns a single merged PDF. To use this, you must sign up for a ConvertAPI account and obtain your API secret key for authentication.
   
   💾 Step 4: Save the Merged PDF Locally
   
   Finally, the merged file is written to the disk using the "Write Result File to Disk" node. This node takes the binary file exported from the previous API request and writes it under the filename document.pdf. The file is saved on the server or local environment where n8n is hosted.
   
   📝 Additional Notes
   
   There’s also a Sticky Note node with a helpful reminder about authentication:
   
   “Authentication: Conversion requests must be authenticated. Please create a ConvertAPI account to get authentication secret.”
   
   ✨ Why Use This Workflow?
   
   This workflow is useful for developers, marketers, legal professionals, or anyone dealing with document automation. Use cases include:
   
   - Generating PDF reports from multiple file sources automatically
   - Weekly or monthly document consolidation workflows
   - Single-click PDF merging from predefined URLs
   
   🔐 API Authentication Reminder
   
   Don’t forget that ConvertAPI requires authentication. Make sure to set up your Query Auth credentials in n8n using your API secret key from ConvertAPI.
   
   📦 Reusability and Scalability
   
   This workflow is modular, allowing you to:
   
   - Add more file downloads
   - Merge additional PDFs by extending the files[] body parameter list
   - Schedule it with Cron or webhook triggers
   - Integrate with services like Google Drive, Dropbox, or Email to automate further steps

   Conclusion
   
   n8n makes automating repetitive processes like PDF file merging both intuitive and powerful. By combining simple HTTP Request nodes with the ConvertAPI service, users can merge multiple PDF files on-demand or on a schedule. Whether you're building an internal document flow or a client-facing automation, this workflow provides a reliable foundation with minimal setup.
   
   Don't wait to streamline your processes — grab your ConvertAPI key, import this n8n workflow, and let the automation begin!

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.
