Walmart Product API: Does It Exist?

Walmart does not offer a standalone Walmart Product API for public use. A true product API would allow developers to access product details like descriptions, prices, and stock levels programmatically. While Walmart provides APIs for partners and sellers, such as the Marketplace API, these are meant for managing product listings and orders, not for public product data access.

Without a dedicated product API, businesses often resort to web scraping for data. This presents challenges like compliance with terms of service, handling dynamic content, and bypassing anti-bot measures.

Get Access to Walmart APIs

Unfortunately all of the Walmart APIs are not public and require you to be a partner or supplier to get access to them. Here are the steps required to get access to Walmart APIs:

For Marketplace API:

1. If you're an existing Walmart Seller you can login to Walmart Developer Portal and generate your API kes there
2. If you're not a seller you can still get access as solution provider by filling out an solution provider application form. Then proceed to the developer portal to generate your API keys.

For Walmart 1P Suppliers:

1. Apply to become a supplier on Walmart's supplier network through the Walmart supplier application form
2. Complete supplier registration & onboarding process to receive Walmart Retail-Link credentials.
3. Use Retail-Link credentials to access Walmart APIs through the Walmart Developer Portal.

For remaining APIs like Advertising API, GoLocal APIs and Transportation Carrier APIs you need to be Walmart's partner directly and there are no public application forms.

If you do not fall into any of the above categories, you can still access public Walmart data through web scraping. Let's take a look at that next!

Web Scraping Walmart: An Alternative Approach

In the absence of a public product API, web scraping becomes a practical way to collect product data from Walmart.com. This method involves programmatically navigating and extracting information from web pages while adhering to ethical guidelines and Walmart's terms of service.

Scrape Walmart with Scrapfly

For those seeking efficient solutions, Scrapfly offers advanced tools for web scraping, tackling challenges like IP blocking, CAPTCHA, and dynamic content. Scrapfly’s Walmart scraper code provides a practical example of scraping using Python.

Below are key excerpts from walmart.py, demonstrating how Scrapfly simplifies the process of web scraping Walmart's product data using Python:

import os
import json
from scrapfly import ScrapeConfig, ScrapflyClient

# Initialize Scrapfly client with API key
SCRAPFLY = ScrapflyClient(key=os.environ["SCRAPFLY_KEY"])

# Base configuration to handle Walmart's anti-scraping measures
BASE_CONFIG = {
    "asp": True,  # Anti-scraping protection bypass
    "country": "US",  # Set proxy country
}

# Function to parse product data from a product page response
def parse_product(response):
    sel = response.selector
    data = json.loads(sel.xpath('//script[@id="__NEXT_DATA__"]/text()').get())
    product_data = data["props"]["pageProps"]["initialData"]["data"]["product"]
    # Extract only the necessary fields
    product = {k: v for k, v in product_data.items() if k in ["name", "priceInfo", "brand"]}
    return product

# Function to scrape multiple product URLs concurrently
async def scrape_products(urls):
    to_scrape = [ScrapeConfig(url, **BASE_CONFIG) for url in urls]
    results = []
    async for response in SCRAPFLY.concurrent_scrape(to_scrape):
        results.append(parse_product(response))
    return results

This example highlights how Scrapfly's tools facilitate seamless web scraping by handling anti-scraping mechanisms, enabling efficient data extraction, and supporting concurrent scraping for faster processing.
