Actor - Walmart Scraper

Walmart scraper

Since Walmart doesn't provide an API, this actor should help you to retrieve data from it.

Now with location support!

The Walmart data scraper supports the following features:

• Scrape product details - You can scrape attributes like images, seller information, photos, brands, variants, ID of the product, and many more. You can find details below.

• Get product reviews! - Now you can gather up all the reviews that has been submitted for a product. Blazing fast with no limitation!

• Scrape search results - You can scrape for a specific search result by keyword.

• Scrape using location - You can use a US postal code to set the location.

• Scrape and filter any categories - You can provide any category with any kind of filter that you want.

• Scrape a parent category and get all the items in its subcategory - You can provide any parent(big) category and let the actor to scrape its sub-categories

• Define the maximum number of pages that needs to be scraped - If you only want to scrape the first 3 pages, there is an option for that.

Walmart specific

Don't worry when you get a little bit different products than you saw on the browser page. Walmart is ordering products differently for each user.

Need to find product pairs between Walmart and another online shop?

Use the AI Product Matcher🔗. This AI model allows you to compare items from different web stores, identifying exact matches and comparing real-time data obtained via web scraping.

With the AI Product Matcher, you can use scraped product data to monitor product matches across the industry, implement dynamic pricing for your website, replace or complement manual mapping, and obtain realistic estimates against your competition for upcoming promo campaigns. Most importantly, it is relatively easy to get started with (just follow this guide) and can match thousands of product pairs.

Input Parameters

The input of this scraper should be JSON containing the list of pages on Walmart that should be visited. Possible fields are:

• search: (Optional) (String) Keyword that can be searched in Walmart search engine.

• postalCode: (Optional) (Number) The US postal code used to set the location. This field will be depreciated soon. Please use zipCode.

• zipCode: (Optional) (Number) The US postal code used to set the location.

• startUrls: (Optional) (Array) List of Walmart URLs. You should only provide category detail, product detail, or search URLs.

• endPage: (Optional) (Number) Final number of page that you want to scrape. The default is Infinite. This applies to all search requests and startUrls individually.

• maxItems: (Optional) (Number) You can limit scraped items. This should be useful when you search through the big lists or search results.

• includeReviews: (Optional) (Boolean) This option allows you to include all product reviews in the scraped data.

• onlyReviews: (Optional) (Boolean) Discards the product data and only retrieves the reviews when includeReviews is true.

• proxy: (Required) (Proxy Object) Proxy configuration.

• extendOutputFunction: (Optional) (String) Function that takes a JQuery handle ($) as an argument and returns an object with data.

• outputFilterFunction: (Optional) (String) Function that takes an output item as an argument and returns the mapped data.

This solution requires the use of Proxy servers, either your own proxy servers or you can use Apify Proxy.

Tip

Please keep in mind that for the sake of not losing any of the data, the actor returns all the possible output. That's it's suggested to use outputFilterFunction all the time.

When you want to have filtering over a category URL; go to Walmart, create filters over the category, and copy and paste the link as one of the startUrl.

If you would like to scrape only the first page of a search list or category list, then put the link for the page and have the endPage as 1.

With the last approach that is explained above you can also fetch any interval of pages. If you provide the 5th page of a category and define the endPage parameter as 6 then you'll have the 5th and 6th pages only.

Output Filter Function

This function is used for mapping the output data that the actor scrapes from the target. It has the following implementation:

data = eval(outputFilterFunction)(data);

So you can use this function to retrieve only the attributes you'd like to have. The following example is for retrieving only id and name attributes:

1(object) => ({
2    id: object.id,
3    name: object.name
4})

Compute Unit Consumption

The actor is optimized to run blazing fast and scrape many products as possible. Therefore, it forefronts all product detail requests. If the actor doesn't block very often it'll scrape 50 products in 2 minutes with ~0.3-0.5 compute units.

During the Run

During the run, the actor will output messages letting you know what is going on. Each message always contains a short label specifying which page from the provided list is currently specified.

When items are loaded from the page, you should see a message about this event with a loaded item count and total item count for each page.

If you provide incorrect input to the actor, it will immediately stop with a failure state and output an explanation of what is wrong.

Walmart Export

During the run, the actor stores results into a dataset. Each item is a separate item in the dataset.

You can manage the results in any language (Python, PHP, Node JS/NPM). See the FAQ or our API reference to learn more about getting results from this Walmart actor.
