Interact with Outscraper API

Actions49

Overview

The Walmart Review - Reviews operation node interacts with the Outscraper API to retrieve product reviews from Walmart product pages. It is designed to extract customer feedback and ratings for Walmart products by specifying product URLs.

This node is beneficial in scenarios such as:

  • Market research: Analyzing customer sentiment and product reception on Walmart.
  • Competitive analysis: Comparing reviews of similar products.
  • Customer service automation: Monitoring new reviews for timely responses.
  • Data aggregation: Collecting review data for dashboards or reports.

For example, a user can input a Walmart product URL and request up to 50 reviews sorted by helpfulness to understand what customers appreciate or dislike about the product.

Properties

Name Meaning
Query Links to Walmart products (e.g., https://www.walmart.com/ip/...). Required to specify which product(s) to fetch reviews for.
Limit Max number of review results to return. Must be at least 1. Default is 50.
Sort Sort order for reviews. Options: Helpful, Rating Ascending, Rating Descending, Relevancy, Submission Ascending, Submission Descending. Default is Helpful.
Cutoff Oldest timestamp value for items; filters out reviews older than this timestamp. Overrides sort to newest first if set. Default is 0 (no cutoff).
Async Request Whether to make an asynchronous request. If true, the task runs asynchronously and may use webhook callback. Default is false.
Webhook URL address to which Outscraper will send a POST request once the asynchronous task is finished. Used only if Async Request is true.
Additional Fields Collection of optional parameters:
• Fields: Specific fields to return (comma-separated list).
• UI: Whether to execute the request as a UI task (boolean).

Output

The node outputs JSON data containing the retrieved Walmart product reviews. Each item typically includes details such as reviewer name, rating, review text, submission date, helpful votes, and other metadata depending on requested fields.

If asynchronous mode is enabled, the output may initially contain task status information, and the final review data will be sent to the specified webhook URL upon completion.

No binary data output is involved.

Dependencies

  • Requires an active Outscraper API key credential configured in n8n.
  • The node sends HTTP requests to the Outscraper API endpoint defined by the user's credentials.
  • For asynchronous requests, a publicly accessible webhook URL must be provided to receive callbacks.

Troubleshooting

  • Common issues:

    • Invalid or missing Walmart product URLs in the Query property will result in no data or errors.
    • Exceeding API rate limits or quota may cause request failures.
    • Incorrect API key or misconfigured credentials will lead to authentication errors.
    • Using asynchronous mode without a valid webhook URL will prevent receiving results.

  • Error messages:

    • Authentication errors indicate invalid or missing API keys; verify credentials.
    • "Invalid query" or "No results found" suggests malformed or unsupported product URLs.
    • Network or timeout errors may require checking connectivity or increasing timeouts.
    • Webhook delivery failures occur if the webhook URL is unreachable or rejects POST requests.
