+
+
+# Track Redfin real estate listings with ScrapeOps, Google Sheets, and Slack
+
+# 1. Workflow Overview
+
+This workflow monitors Redfin real estate listings on a recurring schedule, using ScrapeOps to fetch and parse listing pages, Google Sheets to store property rows, and Slack to send a completion message.
+
+Its main use case is automated property tracking for a specific Redfin search URL such as a city, ZIP code, or filtered results page. It is designed for users who want periodic snapshots of listings without manually browsing Redfin.
+
+The workflow is organized into four functional blocks:
+
+## 1.1 Trigger & Configuration
+The workflow starts on a 6-hour schedule and defines the Redfin search page to scrape.
+
+## 1.2 Fetch & Parse Listings
+It loads the Redfin page through ScrapeOps Proxy with JavaScript rendering enabled, then sends the resulting HTML to the ScrapeOps Parser API configured for the Redfin domain.
+
+## 1.3 Transform & Filter
+The parsed response is enriched with search metadata, split into one item per property, normalized into sheet-friendly fields, and filtered to keep only valid listings.
+
+## 1.4 Save & Notify
+Valid listings are appended to Google Sheets, and a Slack message is sent as a run summary.
+
+---
+
+# 2. Block-by-Block Analysis
+
+## 2.1 Trigger & Configuration
+
+### Overview
+This block defines when the workflow runs and which Redfin search page will be scraped. It acts as the entry point and runtime configuration layer.
+
+### Nodes Involved
+- ` Schedule Trigger`
+- `Set Search Parameters`
+
+### Node Details
+
+#### ` Schedule Trigger`
+- **Type and technical role:** `n8n-nodes-base.scheduleTrigger`  
+  Entry node that launches the workflow automatically at a fixed interval.
+- **Configuration choices:**
+  - Runs every 6 hours.
+- **Key expressions or variables used:**
+  - No custom expression in the node itself.
+  - Produces standard schedule metadata such as timestamp and readable date/time.
+- **Input and output connections:**
+  - No input, as it is a trigger.
+  - Outputs to `Set Search Parameters`.
+- **Version-specific requirements:**
+  - Uses type version `1.1`.
+- **Edge cases or potential failure types:**
+  - Workflow must be activated for the schedule to run.
+  - Server timezone may affect perceived execution timing.
+  - Missed executions can happen if the n8n instance is offline.
+- **Sub-workflow reference:**
+  - None.
+
+#### `Set Search Parameters`
+- **Type and technical role:** `n8n-nodes-base.set`  
+  Defines the Redfin URL that downstream nodes use for scraping and parsing.
+- **Configuration choices:**
+  - Creates a single field:
+    - `redfin_url = https://www.redfin.com/city/21853/MD/California`
+- **Key expressions or variables used:**
+  - Static string value for `redfin_url`.
+- **Input and output connections:**
+  - Input from ` Schedule Trigger`
+  - Output to `ScrapeOps: Fetch Redfin Page (Proxy)`
+- **Version-specific requirements:**
+  - Uses type version `3.2`.
+- **Edge cases or potential failure types:**
+  - If the Redfin URL is invalid, changed, blocked, or points to an empty page, downstream scraping/parsing may fail or return no results.
+  - If Redfin page structure changes significantly, parser output may degrade.
+- **Sub-workflow reference:**
+  - None.
+
+---
+
+## 2.2 Fetch & Parse Listings
+
+### Overview
+This block retrieves the target Redfin page with browser-like rendering and then extracts structured listing data using ScrapeOps parsing specialized for Redfin.
+
+### Nodes Involved
+- `ScrapeOps: Fetch Redfin Page (Proxy)`
+- `ScrapeOps: Parse Redfin Listings`
+
+### Node Details
+
+#### `ScrapeOps: Fetch Redfin Page (Proxy)`
+- **Type and technical role:** `@scrapeops/n8n-nodes-scrapeops.ScrapeOps`  
+  Uses ScrapeOps Proxy API to request the Redfin page with anti-bot and rendering options.
+- **Configuration choices:**
+  - URL comes from `{{$json.redfin_url}}`
+  - Advanced options:
+    - `wait: 5000`
+    - `scroll: 2000`
+    - `country: us`
+    - `render_js: true`
+    - `device_type: desktop`
+    - `residential_proxy: true`
+- **Key expressions or variables used:**
+  - `={{ $json.redfin_url }}`
+- **Input and output connections:**
+  - Input from `Set Search Parameters`
+  - Output to `ScrapeOps: Parse Redfin Listings`
+- **Version-specific requirements:**
+  - Uses type version `1`.
+  - Requires the ScrapeOps n8n node package to be installed in the environment.
+  - Requires ScrapeOps credentials configured in n8n.
+- **Edge cases or potential failure types:**
+  - ScrapeOps authentication failure or missing API key.
+  - Redfin anti-bot response despite proxy usage.
+  - Rendering timeout or incomplete page load.
+  - Empty results if wait/scroll settings are insufficient.
+  - Network errors, quota limits, or provider-side outage.
+- **Sub-workflow reference:**
+  - None.
+
+#### `ScrapeOps: Parse Redfin Listings`
+- **Type and technical role:** `@scrapeops/n8n-nodes-scrapeops.ScrapeOps`  
+  Sends fetched page HTML to the ScrapeOps Parser API and requests structured extraction for the Redfin domain.
+- **Configuration choices:**
+  - `apiType = parserApi`
+  - `parserUrl` uses the original search URL from `Set Search Parameters`
+  - `parserHtml` uses the upstream fetched content
+  - `parserDomain = redfin`
+- **Key expressions or variables used:**
+  - `={{ $('Set Search Parameters').item.json.redfin_url }}`
+  - `={{ $json }}`
+- **Input and output connections:**
+  - Input from `ScrapeOps: Fetch Redfin Page (Proxy)`
+  - Output to `Add Search Metadata`
+- **Version-specific requirements:**
+  - Uses type version `1`.
+  - Also depends on the ScrapeOps node package and credentials.
+- **Edge cases or potential failure types:**
+  - Parser may fail if the upstream node does not return expected HTML/body format.
+  - Parser output structure may change if ScrapeOps updates Redfin parsing schema.
+  - Invalid parser domain or malformed HTML can produce empty `data.search_results`.
+- **Sub-workflow reference:**
+  - None.
+
+---
+
+## 2.3 Transform & Filter
+
+### Overview
+This block converts parser output into operational records. It extracts search-level metadata, splits the listing array into separate items, maps listing fields into normalized columns, and filters out unusable properties.
+
+### Nodes Involved
+- `Add Search Metadata`
+- `Split Properties Into Items`
+- `Format Property Fields`
+- `Filter Valid Properties`
+
+### Node Details
+
+#### `Add Search Metadata`
+- **Type and technical role:** `n8n-nodes-base.set`  
+  Adds summary data from the parsed Redfin response, including timestamps and search context.
+- **Configuration choices:**
+  - Creates fields intended to include:
+    - `timestamp`
+    - `search_title`
+    - `search_type`
+    - `total_properties`
+    - region information
+    - price range
+    - average price
+    - source URL
+    - `search_results`
+- **Key expressions or variables used:**
+  - `={{ new Date().toISOString() }}`
+  - `={{ $json.data.search_information.search_title || 'N/A' }}`
+  - `={{ $json.data.search_information.search_type || 'N/A' }}`
+  - `={{ $json.data.search_information.total_count || 0 }}`
+  - `={{ $json.data.search_information.region.name + ', ' + $json.data.search_information.region.state || 'N/A' }}`
+  - `={{ ($json.data.search_information.min_price || 0) + ' - ' + ($json.data.search_information.max_price || 0) }}`
+  - `={{ $json.data.search_information.average_price || 0 }}`
+  - `={{ $json.url || 'N/A' }}`
+  - `={{ $json.data.search_results }}`
+- **Input and output connections:**
+  - Input from `ScrapeOps: Parse Redfin Listings`
+  - Output to `Split Properties Into Items`
+- **Version-specific requirements:**
+  - Uses type version `3.2`.
+- **Edge cases or potential failure types:**
+  - Several field names appear malformed in the configuration, with names starting with `=` or containing full expressions. This may create unexpected output keys in n8n.
+  - The expression for region concatenation can error if `region` is missing, because `.name` and `.state` are accessed before fallback handling.
+  - If `search_results` is missing or not valid JSON/array, the next node fails.
+- **Sub-workflow reference:**
+  - None.
+
+#### `Split Properties Into Items`
+- **Type and technical role:** `n8n-nodes-base.code`  
+  Converts the search results payload into one n8n item per property.
+- **Configuration choices:**
+  - JavaScript logic:
+    - Reads `search_results` from the first input item.
+    - If it is a string, parses it with `JSON.parse`.
+    - Verifies the result is an array.
+    - Returns each property as its own item.
+- **Key expressions or variables used:**
+  - `const searchResults = $input.first().json.search_results;`
+  - `JSON.parse(searchResults)`
+  - Throws `new Error('search_results is not an array')` if validation fails.
+- **Input and output connections:**
+  - Input from `Add Search Metadata`
+  - Output to `Format Property Fields`
+- **Version-specific requirements:**
+  - Uses type version `2`.
+- **Edge cases or potential failure types:**
+  - Invalid JSON string in `search_results`.
+  - `search_results` missing or null.
+  - Non-array payload causes explicit node failure.
+  - Large result sets may increase execution time and memory usage.
+- **Sub-workflow reference:**
+  - None.
+
+#### `Format Property Fields`
+- **Type and technical role:** `n8n-nodes-base.set`  
+  Normalizes raw property objects into consistent fields for later filtering and storage.
+- **Configuration choices:**
+  - Produces fields such as:
+    - `property_address`
+    - `property_price`
+    - `property_type`
+    - `bedrooms`
+    - `bathrooms`
+    - `bathrooms_full`
+    - `bathrooms_half`
+    - `square_footage`
+    - `lot_area`
+    - `year_built`
+    - `listing_status`
+    - `days_on_market`
+    - `mls_id`
+    - `property_url`
+    - `photo_url`
+    - `location`
+    - `description`
+    - `hoa_fee`
+    - `price_per_sqft`
+    - `sold_date`
+    - `time_zone`
+    - `country`
+    - `badges`
+    - `latitude`
+    - `longitude`
+- **Key expressions or variables used:**
+  - `={{ $json.address || $json.title || 'N/A' }}`
+  - `={{ $json.price || 0 }}`
+  - `={{ $json.property_type || 'N/A' }}`
+  - `={{ ($json.description || '').substring(0, 200) + '...' }}`
+  - `={{ ($json.badges || []).join(', ') || 'None' }}`
+  - `={{ $json.lat_long?.latitude || 0 }}`
+  - `={{ $json.lat_long?.longitude || 0 }}`
+- **Input and output connections:**
+  - Input from `Split Properties Into Items`
+  - Output to `Filter Valid Properties`
+- **Version-specific requirements:**
+  - Uses type version `3.2`.
+- **Edge cases or potential failure types:**
+  - Several configured field names again start with `=` or appear malformed.
+  - There is an empty object in the field list, which may indicate an accidental blank field entry.
+  - `price_per_sqft` uses `price_per_sqrf`, which may be a typo and produce zeros/undefined values.
+  - This node creates `property_price`, but the filter node checks `price`, not `property_price`.
+  - Original fields may or may not still be present depending on Set-node behavior and n8n settings; this affects downstream consistency.
+- **Sub-workflow reference:**
+  - None.
+
+#### `Filter Valid Properties`
+- **Type and technical role:** `n8n-nodes-base.if`  
+  Filters items to retain only listings with a non-placeholder address and a non-zero price.
+- **Configuration choices:**
+  - Conditions are combined with `AND`.
+  - Condition 1: `property_address != 'N/A'`
+  - Condition 2: numeric `price != 0`
+- **Key expressions or variables used:**
+  - `={{ $json.property_address }}`
+  - `={{ $json.price }}`
+- **Input and output connections:**
+  - Input from `Format Property Fields`
+  - True output goes to:
+    - `Save Listings to Google Sheets`
+    - `Send Slack Summary`
+  - False branch is unused.
+- **Version-specific requirements:**
+  - Uses type version `2`.
+- **Edge cases or potential failure types:**
+  - Likely logic inconsistency: upstream formatting creates `property_price`, but this node validates `price`.
+  - Because of that mismatch, valid properties could be rejected if `price` no longer exists.
+  - Strict type validation may fail if values are strings instead of numbers.
+- **Sub-workflow reference:**
+  - None.
+

+
+## 2.4 Save & Notify
+
+### Overview
+This block persists filtered properties to Google Sheets and sends a Slack message after or during processing. It is the output layer of the workflow.
+
+### Nodes Involved
+- `Save Listings to Google Sheets`
+- `Send Slack Summary`
+
+### Node Details
+
+#### `Save Listings to Google Sheets`
+- **Type and technical role:** `n8n-nodes-base.googleSheets`  
+  Appends property data as rows into a specific spreadsheet tab.
+- **Configuration choices:**
+  - Operation: `append`
+  - Spreadsheet ID: `1FYbt_m8nUdlkSmCzwZeBjgp4js6sdIKpiyyTIPBsigQ`
+  - Sheet: `gid=0` / cached as `Sheet1`
+  - Mapping mode: define fields manually
+  - Type conversion disabled
+  - Uses a fixed schema including columns such as Address, Price, Bedrooms, Bathrooms, Photo_URL, Property_URL, Coordinates, etc.
+- **Key expressions or variables used:**
+  - `Price = {{ $('Filter Valid Properties').item.json.price }}`
+  - `Badges = {{ $json.badges }}`
+  - `MLS_ID = {{ $json.mls_id }}`
+  - `Status = {{ $json.listing_status }}`
+  - `Address = {{ $json.address }}`
+  - `HOA_Fee = {{ $json.hoa_fee }}`
+  - `Has_HOA = {{ $json.hoa }}`
+  - `Bedrooms = {{ $json.bedrooms }}`
+  - `Location = {{ $json.property_address }}`
+  - `Bathrooms = {{ $json.bathrooms }}`
+  - `Lot_Acres = {{ $json.lot_area }}`
+  - `Photo_URL = {{ $json.photo }}`
+  - `Scraped_At = {{ new Date().toISOString() }}`
+  - `Year_Built = {{ $json.year_built }}`
+  - `Coordinates = {{ $json.lat_long.latitude }}, {{ $json.lat_long.longitude }}`
+  - `Description = {{ $json.description }}`
+  - `Square_Feet = {{ $json.square_footage }}`
+  - `Property_URL = {{ $json.property_url }}`
+  - `Property_Type = {{ $('Filter Valid Properties').item.json.property_type }}`
+  - `Price_Per_SqFt = {{ $json.price_per_sqrf }}`
+- **Input and output connections:**
+  - Input from `Filter Valid Properties`
+  - Output to `Send Slack Summary`
+- **Version-specific requirements:**
+  - Uses type version `4.4`.
+  - Requires Google Sheets OAuth2 credentials.
+- **Edge cases or potential failure types:**
+  - There are multiple field mismatches:
+    - `Address` maps from `$json.address`, while normalized field is `property_address`.
+    - `Photo_URL` maps from `$json.photo`, while normalized field appears to be `photo_url`.
+    - `Coordinates` expects `$json.lat_long.*`, while normalized fields are `latitude` and `longitude`.
+    - `Price_Per_SqFt` again references `price_per_sqrf`.
+  - If the Google Sheet columns do not match exactly, append may fail or create incomplete rows.
+  - Spreadsheet permissions, expired OAuth token, or wrong document ID can break execution.
+  - Concurrent high-volume appends may hit API quotas.
+- **Sub-workflow reference:**
+  - None.
+
+#### `Send Slack Summary`
+- **Type and technical role:** `n8n-nodes-base.slack`  
+  Posts a message to a Slack channel indicating scrape completion.
+- **Configuration choices:**
+  - Sends a fixed text message:
+    - `🏠 Redfin Scrape Complete! | Sheet: https://docs.google.com/spreadsheets/d/1FYbt_m8nUdlkSmCzwZeBjgp4js6sdIKpiyyTIPBsigQ`
+  - Target is a selected Slack channel.
+  - `executeOnce = true`, so the message should be sent once per execution rather than once per item.
+- **Key expressions or variables used:**
+  - No dynamic count expression is included, despite the sticky note mentioning listing count.
+- **Input and output connections:**
+  - Inputs from:
+    - `Filter Valid Properties`
+    - `Save Listings to Google Sheets`
+  - No downstream output.
+- **Version-specific requirements:**
+  - Uses type version `2.1`.
+  - Requires Slack API credentials.
+- **Edge cases or potential failure types:**
+  - Slack auth/permission issues.
+  - Channel not found or bot not invited.
+  - Because the node has two incoming branches, runtime behavior depends on item flow and execution semantics; `executeOnce` reduces duplicate posting but does not make this a true merge node.
+  - Message is static, so it does not confirm actual row count or success count.
+- **Sub-workflow reference:**
+  - None.

+# 4. Reproducing the Workflow from Scratch
+
+Below is a practical rebuild sequence in n8n. It mirrors the current workflow, while also noting places where the original configuration contains inconsistencies that you may want to correct during implementation.
+
+## Prerequisites
+1. Install or enable n8n.
+2. Install the ScrapeOps n8n node package if it is not already available in your instance.
+3. Prepare credentials:
+   - **ScrapeOps API credentials**
+   - **Google Sheets OAuth2 credentials**
+   - **Slack API credentials**
+4. Duplicate or create a Google Sheet with columns matching the intended schema.
+
+## Step-by-step build
+
+1. **Create a Schedule Trigger node**
+   - Type: `Schedule Trigger`
+   - Set interval to every `6 hours`.
+   - This is the workflow entry point.
+
+2. **Create a Set node named `Set Search Parameters`**
+   - Type: `Set`
+   - Add one field:
+     - `redfin_url` as string
+     - Example value: `https://www.redfin.com/city/21853/MD/California`
+   - Connect `Schedule Trigger` → `Set Search Parameters`.
+
+3. **Create a ScrapeOps node named `ScrapeOps: Fetch Redfin Page (Proxy)`**
+   - Type: `ScrapeOps`
+   - Use ScrapeOps credentials.
+   - Configure:
+     - URL: `{{$json.redfin_url}}`
+     - Wait: `5000`
+     - Scroll: `2000`
+     - Country: `us`
+     - Render JS: enabled
+     - Device type: `desktop`
+     - Residential proxy: enabled
+   - Connect `Set Search Parameters` → `ScrapeOps: Fetch Redfin Page (Proxy)`.
+
+4. **Create another ScrapeOps node named `ScrapeOps: Parse Redfin Listings`**
+   - Type: `ScrapeOps`
+   - Use the same ScrapeOps credentials.
+   - Configure:
+     - API Type: `Parser API`
+     - Parser Domain: `redfin`
+     - Parser URL: `{{ $('Set Search Parameters').item.json.redfin_url }}`
+     - Parser HTML: `{{ $json }}`
+   - Connect `ScrapeOps: Fetch Redfin Page (Proxy)` → `ScrapeOps: Parse Redfin Listings`.
+
+5. **Create a Set node named `Add Search Metadata`**
+   - Type: `Set`
+   - Add fields for search metadata. To reproduce the workflow cleanly, use these recommended field names:
+     - `timestamp` → `{{ new Date().toISOString() }}`
+     - `search_title` → `{{ $json.data.search_information.search_title || 'N/A' }}`
+     - `search_type` → `{{ $json.data.search_information.search_type || 'N/A' }}`

+     const searchResults = $input.first().json.search_results;
+
+     const propertiesArray = typeof searchResults === 'string'
+       ? JSON.parse(searchResults)
+       : searchResults;
+
+     if (!Array.isArray(propertiesArray)) {
+       throw new Error('search_results is not an array');
+     }
+
+     return propertiesArray.map((property, index) => ({
+       json: property,
+       pairedItem: { item: 0 }
+     }));
+     ```
+   - Connect `Add Search Metadata` → `Split Properties Into Items`.
+
+7. **Create a Set node named `Format Property Fields`**

+   - Type: `If`
+   - Set `AND` logic.
+   - Conditions:
+     - `{{$json.property_address}}` is not equal to `N/A`
+     - `{{$json.property_price}}` is not equal to `0`
+   - Important: use `property_price`, not `price`, if you want this block to align with the formatting node.
+   - Connect `Format Property Fields` → `Filter Valid Properties`.
+
+9. **Create a Google Sheets node named `Save Listings to Google Sheets`**
+   - Type: `Google Sheets`
+   - Credentials: Google Sheets OAuth2.
+   - Operation: `Append`
+   - Select your spreadsheet.
+   - Select target sheet/tab.
+   - Enable manual field mapping.
+   - Map columns such as:
+     - `Address` → `{{ $json.property_address }}`
+     - `Price` → `{{ $json.property_price }}`
+     - `Property_Type` → `{{ $json.property_type }}`
+     - `Bedrooms` → `{{ $json.bedrooms }}`
+     - `Bathrooms` → `{{ $json.bathrooms }}`
+     - `Square_Feet` → `{{ $json.square_footage }}`
+     - `Lot_Acres` → `{{ $json.lot_area }}`
+     - `Year_Built` → `{{ $json.year_built }}`
+     - `Status` → `{{ $json.listing_status }}`
+     - `MLS_ID` → `{{ $json.mls_id }}`
+     - `Price_Per_SqFt` → `{{ $json.price_per_sqft }}`
+     - `HOA_Fee` → `{{ $json.hoa_fee }}`
+     - `Location` → `{{ $json.location }}`
+     - `Description` → `{{ $json.description }}`
+     - `Photo_URL` → `{{ $json.photo_url }}`
+     - `Property_URL` → `{{ $json.property_url }}`
+     - `Coordinates` → `{{ $json.latitude }}, {{ $json.longitude }}`
+     - `Scraped_At` → `{{ new Date().toISOString() }}`
+     - `Badges` → `{{ $json.badges }}`
+   - Connect the **true** output of `Filter Valid Properties` → `Save Listings to Google Sheets`.
+
+10. **Prepare the spreadsheet columns**
+    - Ensure your Google Sheet contains the same column names used in the node mapping.
+    - The original workflow references:
+      - Address
+      - Price
+      - Property_Type
+      - Bedrooms
+      - Bathrooms
+      - Square_Feet
+      - Lot_Acres
+      - Year_Built
+      - Status
+      - MLS_ID
+      - Price_Per_SqFt
+      - HOA_Fee
+      - Has_HOA
+      - Location
+      - Description
+      - Photo_URL
+      - Property_URL
+      - Coordinates
+      - Scraped_At
+      - Badges
+
+11. **Create a Slack node named `Send Slack Summary`**
+    - Type: `Slack`
+    - Credentials: Slack API.
+    - Action: send message to channel.
+    - Select the target channel.
+    - Message example:
+      - `🏠 Redfin Scrape Complete! | Sheet: https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID`
+    - Enable `Execute Once`.
+   - To match the original workflow, connect:
+     - `Filter Valid Properties` → `Send Slack Summary`
+     - `Save Listings to Google Sheets` → `Send Slack Summary`
+   - For a cleaner design, many builders would instead use a Merge or summary node before Slack, but that is not how the provided workflow is wired.
+
+12. **Optionally add sticky notes**
+    - Add documentation notes for each major block:
+      - Trigger & Configuration
+      - Fetch & Parse Listings
+      - Transform & Filter
+      - Save & Notify
+
+13. **Activate and test**
+    - Run manually first.
+    - Check:
+      - ScrapeOps returns rendered HTML
+      - Parser returns `data.search_results`
+      - Code node splits items correctly
+      - Google Sheets receives rows
+      - Slack receives one message
+
+## Credential setup details
+
+### ScrapeOps
+- Create a ScrapeOps account: https://scrapeops.io/app/register/n8n
+- Add ScrapeOps credentials in n8n.
+- Assign the same credential to both ScrapeOps nodes.
+
+### Google Sheets
+- Create OAuth2 credentials in n8n for Google Sheets.
+- Share the target spreadsheet with the authenticated Google account if needed.
+- Use the correct spreadsheet ID and sheet tab.
+
+### Slack
+- Create/connect a Slack app or bot credential in n8n.
+- Ensure the bot can post to the target channel.
+- Invite the bot to the channel if necessary.
+
+## Important implementation cautions
+To reproduce the workflow exactly, you could keep the original field mismatches. To reproduce it reliably, correct the following:
+1. Use `property_price` consistently instead of switching between `price` and `property_price`.
+2. Use `property_address` consistently instead of switching between `address` and `property_address`.
+3. Use `photo_url` consistently instead of `photo`.
+4. Use `latitude`/`longitude` consistently instead of later referencing `lat_long`.
+5. Replace `price_per_sqrf` with `price_per_sqft` if that is the intended source field.
+6. Remove malformed Set field names that start with `=` unless intentionally required.
+7. Remove the blank field entry in `Format Property Fields`.
