This article provides a complete, practical walkthrough of the Splitout Filter 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.

   # Automate Your Accounting: Save Paddle Invoices to Google Drive with n8n
   
   Managing monthly invoices can quickly become tedious—especially if you rely on email notifications and have to manually download, rename, convert, and organize documents. But with n8n, a powerful open-source workflow automation tool, you can fully automate this process. In this guide, we'll walk through a real-world n8n workflow that takes Paddle invoice emails from your Gmail, converts them into PDFs, and neatly stores them into a specified Google Drive folder.
   
   ## The Challenge
   
   Every month, businesses receive invoice emails from billing platforms like Paddle. While the invoices are easy to retrieve, the process of opening each email, clicking the link, downloading the receipt, converting it to a PDF (if needed), renaming the file, and uploading it to the correct Google Drive folder is a repetitive time sink. Automating this task saves time, reduces errors, and ensures consistent archival of financial documents.
   
   ## The Solution
   
   Using n8n, we've built an automated workflow to handle all of this. Here's what it does:
   
   1. Monitors your Gmail inbox for new messages.
   2. Filters only emails from help@paddle.com with the subject line containing "Your invoice".
   3. Extracts the receipt link from the HTML content of the email.
   4. Downloads the invoice as a PDF using pdflayer.
   5. Uploads the PDF to Google Drive.
   6. Renames the file in a consistent format.
   7. Moves the file to a specified folder in your Google Drive.
   
   Let’s break down the core components of the workflow.
   
   ## Step-by-Step Workflow Breakdown
   
   ### 1. Gmail Trigger
   
   The workflow begins with a Gmail Trigger node set to check for new emails every minute. It connects to your Gmail account using OAuth2 credentials. It listens for any new incoming messages.
   
   ### 2. Setup Configuration
   
   The Setup node stores two key configuration values:
   - `api_key`: Your pdflayer API key.
   - `url_to_drive_folder`: The folder URL in Google Drive where the invoices will be stored.
   
   ### 3. Email Filtering
   
   The "Only n8n Paddle invoice mails" node acts as a gatekeeper. It allows the workflow to proceed only if:
   - The email is from help@paddle.com.
   - The subject line contains the phrase "Your invoice".
   
   Other emails are ignored via a NoOp node, effectively bypassing unnecessary processing.
   
   ### 4. HTML Link Extraction
   
   The email body often contains multiple links, so it's important to extract the correct one. The workflow uses the "Extract 'a-tags' from email" node to extract all hyperlinks (href attributes of anchor tags) using a CSS selector. These are then split into individual items for further evaluation.
   
   ### 5. Link Filtering
   
   From the list of extracted links, the “Only keep invoice link” node filters out links containing the word "/receipt/", identifying the correct invoice link.
   
   ### 6. Invoice PDF Conversion
   
   Using the pdflayer API, the workflow then converts the invoice's URL to a PDF. The "Download Invoice PDF from URL" node sends an HTTP GET request with your API key and the invoice URL to pdflayer, specifying the standard A4 page size.
   
   ### 7. Upload to Google Drive
   
   Once the PDF is generated, the HTTP Request node “Upload PDF to Drive” uploads it to Google Drive using the Drive API with binary file support.
   
   ### 8. File Renaming
   
   To keep files consistent and searchable, the “Rename file” node renames the uploaded file to a format like: 
   ```
   n8n_cloud_invoice_YYYY-MM-DD.pdf
   ```
   The date format is dynamically set using the current timestamp.
   
   ### 9. Move to Final Folder
   
   Finally, the file is moved into the intended Google Drive folder specified in the setup node. This consolidates all invoices into one reliable storage location.
   
   ## Why This Workflow Matters
   
   This automation not only saves time but provides peace of mind. Any business handling frequent transactions with Paddle no longer has to worry about tracking, renaming, or organizing its invoices. The workflow scales effortlessly—once running, it diligently performs these steps without human involvement.
   
   This n8n setup also demonstrates the power of combining multiple services through low-code automation. With built-in customization points, users can extend the logic further: email the PDFs, store them in Dropbox, or send Slack notifications upon successful uploads.
   
   ## APIs in Use
   
   This workflow leverages the following third-party APIs:
   
   | Service        | Purpose |
   |----------------|---------|
   | Gmail API (via n8n Gmail Trigger node) | Triggers the automation by detecting new emails |
   | HTML Parsing (n8n HTML node) | Extracts anchor links from the email body |
   | pdflayer API | Converts the invoice URL into a PDF |
   | Google Drive API (via multiple Google Drive nodes) | Uploads, renames, and moves the PDF files |
   
   ## Conclusion
   
   With just a few clicks and configurations, you can set up a robust automation system using n8n that handles invoice management end-to-end. By integrating Gmail, pdflayer, and Google Drive, this workflow smartly extracts, converts, and saves all Paddle invoices—helping you focus on your business instead of your inbox.
   
   If you’re tired of repetitive invoice-handling tasks, now’s the time to automate them with n8n.

   **Third-Party APIs Used:**
   
   1. Gmail API (via n8n Gmail Trigger)
   2. pdflayer API (https://pdflayer.com) – for generating PDFs from URLs
   3. Google Drive API (for uploading, renaming, and moving files)

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.
