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

   In the world of eCommerce, seamless logistics and accurate delivery addresses can make or break the customer experience. Mistyped house numbers, misspellings, or incomplete street information not only delay shipments but also increase costs and impact customer satisfaction. Enter automation — and more specifically, a clever use of the n8n workflow automation platform, with integrations to Billbee and Endereco APIs.
   
   This article explores a robust n8n workflow designed to automatically validate shipping addresses from Billbee orders using the Endereco Address API. The solution reduces manual effort, prevents shipping errors, and helps warehouse teams operate more efficiently.
   
   From Order Import to Address Correction — An End-to-End Flow
   
   This workflow kicks off the moment a new order hits Billbee. A webhook — configured inside Billbee’s rule engine — sends an HTTP request to your hosted n8n instance, triggering the automation.
   
   Here are the steps that follow:
   
   1. Webhook Trigger from Billbee  
   A webhook passes the order ID to the n8n workflow. Billbee’s rule can be configured to send this webhook whenever a new order is imported or a specific order status is reached (e.g., "packed" or "in fulfillment").
   
   2. Fetch Order Data  
   Using the order ID, the workflow fetches the complete order details from the Billbee API, focusing specifically on the shipping address of the customer.
   
   3. Map Address Fields  
   The next step parses out individual components of the shipping address—like street name, house number, ZIP code, city, and so on. The workflow accommodates nuances, such as cleaning the house number field by removing extra characters like “/”.
   
   House Number Validation: Special Handling  
   One of the most common problems in address validation is the absence or incorrect placement of a house number. The workflow smartly checks if this field is empty or improperly merged into another field.
   
   If the house number is missing, it checks the ‘AddressLine2’ field for numeric values or combinations of numbers and letters:
   - If AddressLine2 is purely numeric, it assumes it was mistakenly filled as the house number.
   - If it contains both digits and letters (e.g., “12A”), it confirms it might be a valid house number.
   - If neither condition is met, the order is tagged for manual review.
   
   4. Filter Out Pickup Stations  
   Certain street entries like “Paketstation”, “Postfiliale”, or “Paketshop” (common in the German logistics landscape) are filtered out, as these require different handling outside the scope of the standard address validation.
   
   5. Call Endereco Address Validation API  
   Once the address is deemed ready, the workflow packages it into a JSON-RPC request and sends it to the Endereco API. Endereco checks the address against postal databases and suggests corrections if needed.
   
   6. Handle API Response  
   If Endereco returns a valid, corrected address, the workflow updates the shipping address within Billbee using a PATCH request. If the API fails to return a suitable address (for example, due to severely malformed input), the workflow tags the order in Billbee with “endereco_address_failed”.
   
   7. Tagging for Transparency  
   All outcomes are tagged in Billbee for full transparency:
   - “endereco_address_validated”: The address was validated successfully and updated.
   - “manual_address_check”: The address needs a human review due to ambiguous or empty fields.
   - “endereco_address_failed”: The Endereco API couldn’t validate the address.
   
   These tags help customer service and fulfillment teams quickly identify problematic orders and act accordingly.
   
   Why This Workflow Matters
   
   eCommerce businesses typically deal with hundreds or thousands of orders daily. Manual address validation is neither scalable nor foolproof. By automating this task in n8n, businesses can:
   - Reduce failed deliveries and costly returns
   - Save time for customer service and warehouse staff
   - Improve the quality of customer data
   - Create a seamless operational experience
   
   Prerequisites
   
   To use this workflow, you’ll need:
   - A Billbee Developer API Key (available from Billbee support)
   - A Billbee User API Key (found in your Billbee account settings)
   - An Endereco API Key (signup available with a 30-day free trial)
   
   Conclusion
   
   This n8n workflow elegantly bridges two powerful services—Billbee for order management and Endereco for address verification—creating an automation that improves data quality and customer satisfaction. If you're running a growing eCommerce operation, this is the kind of automation that delivers immediate ROI and builds a foundation for scale.
   
   Whether you’re a developer, operations manager, or just someone who appreciates well-built workflow automation, this is a powerful example of how APIs and tools like n8n can work together to solve very human problems in very smart ways.

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.
