How to scrape More Seller Options for Walmart Products

Introduction

Walmart offers a massive number of different products that range from food, camping gear to all sorts of electronics, like TVs, laptops and even Air Fryers. With a catalog of items this huge and diverse, there's a lot of value from being able to scrape Walmart products, such as researching and comparing product prices, sizes, quality, and also checking how the different sellers are pricing the same product.

How to know which Walmart products are sold by multiple sellers

When browsing products on Walmart, we can easily see when a product has multiple sellers by checking if the product has the "More Seller Options" box on its product page:

When scraping Walmart Products using SerpApi, we can know when a product has more sellers when we can find the field response[:product_result][:seller_options] in the response:

How to scrape Walmart Product Sellers

There are two options to scrape Walmart Product Sellers:

1. The first one is by using SerpApi's Walmart Product API, and when a product we're scraping has "More Seller Options" we can get the direct link to scrape the product's additional sellers using SerpApi's Walmart Product Sellers API in response[:product_result][:seller_options][:serpapi_product_sellers_link] which returns the Walmart Product Seller results using SerpApi's Walmart Product Sellers API.
2. The second one is by using SerpApi's Walmart Product Sellers API directly, providing the product_id for the product that we want to know about to scrape its "More Seller Options" page.

What is available on Walmart Product Sellers API

Besides information about product sellers, we also get some data about the product itself, for example, the product's name, thumbnail and url. As for the sellers, we get information about their offering related to the product, such as us_item_id, offer_id, offer_type, availability_status, seller_id, seller_name, seller_display_name, seller_type, price, extracted_price and return_policy_text.

Let's create a SerpApi account so we can tap into all the potential Walmart Product Sellers API has to offer.

Setting Up a SerpApi Account

First, we need to create a SerpApi account. SerpApi has a Free tier that offers up to 250 searches per month.
Let's head to the sign-up page to create an account. Provide a valid email and a valid phone number in order to access your account's dashboard.

Exploring Walmart Product Sellers API

Now that we have an account, we can sign in and use SerpApi's Playground technology to explore all the information we can get from Walmart Product Sellers API.
For this example, we're scraping Walmart Product Sellers (engine: walmart_product_sellers) for the product Tajin Clasic Seasoning 14oz (product_id: 138762768). This is a good example product because it has many offerings by several sellers, with different prices and return policies.
Let's see how that looks like:

Integrating SerpApi with your application

Exploring SerpApi's vast diversity of Search APIs using Playground is a lot of fun, but to get the most out of SerpApi's services it's best to use the results from Search Engines directly in your application programmatically.

In order to send requests to SerpApi, we will need your unique secret API key that can be copied right from your dashboard:

Your API key is unique to you and you should never share it anywhere to avoid other people using your account, but in case you accidentally expose your API key, you can easily generate a new one from the Manage API key page (if you generate a new API key, don't forget to update your application code with the newly generated API key).

Check out the documentation for SerpApi libraries based on the programming language you use:

• Ruby
• Python
• JavaScript
• PHP
• Go
• Java
• Dotnet

To demonstrate how simple it is to use SerpApi in your code, here's all you'd need to do to retrieve Walmart Product Sellers API results from your application using the Ruby language, as you can also see in SerpApi's Walmart Product Sellers API documentation page:

require "serpapi" 

client = SerpApi::Client.new(
  engine: "walmart_product_sellers",
  product_id: "138762768",
  api_key: "YOUR_SECRET_API_KEY"
)

results = client.search
full_menu_results = results[:sellers_results]

That's all there is to it. Integrating SerpApi is extremely simple and straightforward. You can explore how to use all other Search Engine APIs offered by SerpApi at our documentation page, and play around with each of them using SerpApi's Playground feature.

Have fun! 😃

In my previous blog post, we could scrape all product listings from Walmart. We have enough data to do market research, price analysis, and more! But it’s missing a lot of information like manufacturer, product type, full product description... This rich data content will be available on Walmart product detail
