This article provides a complete, practical walkthrough of the Schedule Http Update Scheduled n8n agent. It connects Schedule Trigger, Google Sheets, If 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 Schedule Trigger, Google Sheets, If, 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 LinkedIn Contact Data Enrichment Using n8n and Prospeo API
   
   In today's data-driven sales and recruiting environments, having accurate and enriched lead data is critical for successful outreach. Manually searching, copying, and pasting LinkedIn contact details into spreadsheets is inefficient and error-prone. Fortunately, tools like n8n allow you to automate this workflow — saving hours of work and improving data accuracy.
   
   In this article, we’ll walk through a no-code/low-code automation that pulls LinkedIn profile URLs from a Google Sheet, enriches them using the Prospeo.io LinkedIn Email Finder API, and updates the same spreadsheet with key contact information like name, job title, location, skills, and email address.
   
   Let’s dive into how this process is implemented step-by-step inside n8n.
   
   ---
   
   ## 🛠️ The Workflow Overview
   
   The workflow is powered by n8n, an extendable workflow automation tool that allows you to connect APIs, applications, and data sources effortlessly. Here's what the workflow accomplishes:
   
   1. **Trigger the workflow on a schedule**
   2. **Read unfilled LinkedIn profile URLs from Google Sheets**
   3. **Verify if required fields (e.g., Name, Email, Gender) are empty**
   4. **Send the LinkedIn URL to Prospeo.io API for enrichment**
   5. **Extract and format response data**
   6. **Update the Google Sheet record with enriched data**
   
   Let’s explore each component in more detail.

   ## 🔁 1. Schedule Trigger
   
   The first node in the workflow is a Schedule Trigger. This ensures the workflow runs automatically at specified intervals (such as every X minutes). It eliminates the need for manual execution and ensures continuous real-time updates to your lead list.

   ---
   
   ## 📄 2. Read LinkedIn URLs from Google Sheets
   
   Next, the workflow connects to a predefined Google Sheet containing LinkedIn profile URLs, identified by a document ID and sheet name (or gid). n8n utilizes OAuth2 credentials to securely access and read rows from the sheet.

   ---
   
   ## ✅ 3. Conditional Check: Do We Need More Data?
   
   Before making an API request, the workflow evaluates each row to check for missing values. A Conditional Node ensures that requests are only made for entries where the following fields are still blank:
   
   - Name
   - Gender
   - Job Title
   - Summary
   
   Meanwhile, it ensures the "LinkedIn URL" field is populated before continuing.
   
   This approach optimizes API usage and ensures you only enrich rows that actually need more data.

   ---
   
   ## 🌐 4. Prospeo.io LinkedIn Email Finder API
   
   The star of the show here is the Prospeo.io LinkedIn Email Finder API. Once a row qualifies via the conditional check, the workflow sends an HTTP POST request to this API. The request includes the LinkedIn URL and a unique ID for each contact row.
   
   Prospeo’s API returns a JSON object containing valuable contact information, such as:
   
   - Full Name
   - Email Address
   - Gender
   - Job Title
   - Summary
   - Education
   - Skills
   - Profile Picture
   - Location

   ## 🔀 5. Data Merge & Field Formatting
   
   After receiving the API response, the workflow uses a Merge node followed by a Set node to structure the data correctly. Fields are extracted and renamed to match the schema of the Google Sheet, including:
   
   - Name
   - Email
   - Gender
   - Job Title
   - Summary
   - Education
   - Skills
   - Profile Picture URL
   - Location
   
   Merging and formatting is a crucial step in making sure the data aligns with the columns of your existing spreadsheet for smooth updating downstream.
   
   ---
   
   ## 📤 6. Update Your Google Sheet
   
   Lastly, the updated data is written back into the original Google Sheet. Using the row's unique ID as a match criterion, the workflow performs an "update" operation rather than inserting a new row.
   
   This ensures that data stays centralized and current without creating duplicates or overwriting unintended records.

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.
