Automate Product Data Enrichment with n8n and AI Tools

1. Opening Problem Statement

Meet Sarah, a dedicated building surveyor working against a tight deadline to catalog hundreds of products for a large property inventory. Each item has a photograph and some manual notes, but much of the product information is incomplete or inconsistent. Sarah spends countless hours manually researching products, typing in descriptions, models, materials, and conditions to complete the records. This tedious process not only wastes Sarah’s valuable time but also introduces errors and delays in delivering the final report.

For Sarah, manually enriching product data from survey photos can easily consume 10+ hours per week—time that could be better spent on deeper analysis or client consultations. Misidentifications cause costly revisions, and the back-and-forth searching online for product details becomes a huge bottleneck.

2. What This Automation Does

This n8n workflow is designed specifically for surveyors like Sarah, who need to automate the enrichment of product data directly from survey photos stored in Airtable. When this workflow is triggered, it performs several well-coordinated actions, including AI-powered image analysis and intelligent internet research:

• Automatically scans Airtable rows to identify product photos needing AI analysis.
• Uses OpenAI’s vision model to analyze images and extract initial product descriptors like description, model, material, color, and condition.
• Runs an AI Agent that leverages custom tools to:
• Perform reverse image searches via SERP API for matching products online.
• Scrape relevant webpages using Firecrawl’s web scraper to gather additional product information in markdown format.
• Parses and refines AI outputs into structured product data.
• Automatically updates Airtable rows with enriched product data, marking them as processed.
• Failsafe and routing mechanisms ensure robust handling of tool unavailability or errors.

Benefits: Sarah can save upwards of 8-12 hours per week on manual data entry. The workflow improves data accuracy by leveraging real-time internet research and AI vision, reducing errors and the need for manual intervention drastically.

3. Prerequisites ⚙️

• Airtable account with your database and table ready containing product photos.
• OpenAI account with API access configured for vision and GPT-4o chat model.
• SerpAPI account for reverse image search API access.
• Firecrawl.dev API account for web scraping capabilities.
• n8n cloud or self-hosted instance with API credentials for all above services properly set.

Optional: If you prefer self-hosting n8n, services like Hostinger provide reliable hosting environments for automation workflows.

4. Step-by-Step Guide ✏️

Step 1: Set up Airtable Base & Table IDs

In the Get Applicable Rows node, click the node and set your Airtable Base ID and Table ID that contains your product photo records. Make sure your Airtable has columns for Image and a boolean AI_status.

Expected outcome: When triggered, this node fetches rows with photos where AI_status is false.

Common mistake: Using incorrect IDs or not enabling API permissions can result in no data fetched.

Step 2: Configure OpenAI Vision Model to Analyze Photos

Locate the Analyse Image node (type: OpenAI Image Analysis). Enter a prompt focusing on the product in the photo to identify description, model, materials, colors, and condition. Use the expression {{ $json.Image[0].thumbnails.large.url }} for the image URL parameter.

Expected outcome: You receive a descriptive analysis extracted from the image.

Common mistake: Forgetting to use the correct image URL format or misconfiguring API credentials.

Step 3: Set Up the AI Agent for Product Attribute Enrichment

The Object Identifier Agent node uses GPT-4 functions with defined tools to automatically perform further research. Check the system prompt that instructs the agent to use tools for reverse image search and webpage scraping if initial data is insufficient.

Expected outcome: Enriched product attributes structured as title, description, model, material, color, and condition.

Common mistake: Not connecting tool workflows properly or incorrect prompt frameworks can cause incomplete data output.

Step 4: Configure the Reverse Image Search Tool

This tool uses SERP API’s Google Reverse Image endpoint. In the SERP Google Reverse Image API node, ensure the URL and query parameters are set as:

{
  engine: "google_reverse_image",
  image_url: "={{ $json.query }}"
}

Credentials must be valid for SerpAPI.

Expected outcome: JSON response with URLs pointing to similar images/products online.

Common mistake: Using the generic SERP node instead of custom HTTP request with proper query parameters.

Step 5: Set Up the Firecrawl Web Scraper Tool

Configure the Firecrawl Scrape API node to POST to https://api.firecrawl.dev/v0/scrape with the body containing the URL to scrape. Use header authentication with your Firecrawl API key.

Expected outcome: Markdown content and metadata from the target pages to supplement product info.

Common mistake: Missing Content-Type header or invalid API keys lead to request failures.

Step 6: Use the Actions Router to Direct API Calls

The Actions Router switch node examines the tool routing indicated by route and decides which API to call (reverse image search or scraping). Confirm rules are appropriately defined for “serp.google_reverse_image” and “firecrawl.scrape” routes.

Expected outcome: Requests route correctly to the intended API.

Common mistake: Misconfigured route strings cause fallback errors.

Step 7: Parse and Set Responses

After APIs respond, use Set nodes like Reverse Image Search Response and Firecrawl Scrape Success Response to format the output for the AI agent’s consumption.

Expected outcome: Structured JSON or stringified markdown ready to feed back to the agent.

Common mistake: Incorrect JSON stringification syntax causes parsing errors downstream.

Step 8: Update Airtable Rows with Enriched Data

The Enrich Product Rows Airtable update node maps all AI extracted product attributes back into the Airtable record, including setting the AI_status flag to TRUE.

Expected outcome: Airtable is automatically updated with enriched product details, ready for reporting.

Common mistake: Mapping errors or missing record IDs will cause update failures.

Step 9: Run and Test the Workflow

Trigger the workflow manually using the When clicking “Test workflow” manual trigger node. Check logs and output at each step to validate data flow and API responses.

Expected outcome: Full end-to-end run with enriched data saved back to Airtable.

Common mistake: Forgetting to save before execution or using insufficient test data.

5. Customizations ✏️

• Adjust AI Vision prompt in Analyse Image node: Modify the text prompt to specify additional product attributes or tailor descriptions for your industry.
• Add new tools for the AI Agent: Integrate other custom workflow tools accessible via the tool workflow node to enhance research capabilities (e.g., competitor APIs or inventory databases).
• Filter Rows by Additional Conditions: In the Get Applicable Rows node, tweak Airtable filterByFormula to include criteria like product categories or dates.
• Change Airtable Base/Table IDs: Easily reconfigure which Airtable data source you use by updating those IDs in both the fetch and update nodes.
• Modify the AI Agent prompt: Add more detailed instructions or change the attribute list to match your specific project goals.

6. Troubleshooting 🔧

Problem:

“No applicable rows found when fetching from Airtable.”

Cause:

The filterByFormula or base/table IDs are misconfigured, or records do not meet filter criteria.

Solution:

Double-check your Airtable base and table IDs. Review the filter formula to ensure it correctly matches rows with images and AI_status set to false.

Problem:

“OpenAI API returns errors or no meaningful analysis.”

Cause:

Incorrect image URL path, missing or invalid API credentials, or prompt misconfiguration.

Solution:

Verify the image URL format uses the large thumbnail URL from Airtable images. Confirm your OpenAI API key under credentials. Refine the prompt to be clear and focused on product features.

Problem:

“Firecrawl API requests fail or timeout.”

Cause:

Missing authorization headers or invalid API key; incorrect POST body format.

Solution:

Ensure Content-Type header set to “application/json” is present. Check your API key and reapply credentials. Validate JSON body formatting for the URL parameter.

7. Pre-Production Checklist ✅

• Verify Airtable credentials and ensure API access for read/write operations.
• Confirm OpenAI API key has permissions for vision and chat models.
• Test SerpAPI and Firecrawl API credentials with manual requests.
• Verify correct JSON schema and prompt configuration in AI nodes.
• Run the workflow on a sample record with valid images and check the enriched output.
• Backup original Airtable data before running the workflow in production.

8. Deployment Guide

Once validated, activate the workflow by enabling it within your n8n instance. You can trigger automatically on schedule or via webhook integration (instead of manual trigger) depending on your survey data collection process.

Monitor workflow executions in the n8n dashboard, especially API request success rates and error logs. Set up notification nodes if needed for alerting failures.

9. FAQs

Q: Can I use other reverse image search providers instead of SERP API?

A: Yes, but you’ll need to configure a similar HTTP Request node with correct API endpoints and request formats. SERP API is chosen here for its robust Google reverse image features.

Q: Does this workflow consume a lot of API credits?

A: API usage depends on your volume. OpenAI vision and GPT calls plus API calls to SERP and Firecrawl can add up, so be mindful of your quota and optimize by filtering only necessary records.

Q: Is my data safe with these third-party APIs?

A: Yes, but be sure to review each service’s data security policies. Use encrypted credentials in n8n and avoid sending sensitive personal data if possible.

Q: Can this workflow handle hundreds of records?

A: Yes, but consider rate limits for each API and possibly implement batching or throttling via n8n settings.
