How to Get Walmart API for Free? A Complete Guide with Implementation

Walmart API provides access to extensive data on products, orders, prices, and inventory, making it a powerful tool for developers. However, the official API requires a Walmart Marketplace seller account to obtain access to the production environment. So, how can you access Walmart API for free?

1. Apply for the Official Walmart API

Walmart offers an official API, but full production access requires seller credentials. However, developers can apply for Sandbox (testing) API access for free.

Steps to Apply

1. Register a Walmart Developer Account

   • Visit Walmart Developer Portal and sign up.

2. Obtain API Key

   • Log in, go to API Key Management, and apply for Sandbox API Key (free).

3. Use API for Testing

   • The Sandbox API provides simulated data for development and testing.

Official API Example (Python)

The following Python code retrieves item data from Walmart's Sandbox API:

import requests
headers = {
"WM_SVC.NAME": "Walmart Marketplace",
"WM_QOS.CORRELATION_ID": "your_correlation_id",
"Authorization": "Basic your_encoded_credentials",
"Accept": "application/json"
}
response = requests.get(
"https://sandbox.walmartapis.com/v3/items?limit=10",
headers=headers
)
print(response.json())

Replace "your_encoded_credentials" with your actual API key.

2. Use Walmart's Free Public Data Sources

Even without an API account, you can still access some Walmart data through public RSS feeds.

Retrieve Walmart Product Data via RSS Feeds

Python Example: Parsing Walmart RSS

import feedparser
url = "https://www.walmart.com/rss/browse/bestsellers"
feed = feedparser.parse(url)
for entry in feed.entries:
print(entry.title, entry.link)

This script extracts bestselling items from Walmart's public RSS feed, displaying product titles and URLs.

3. Use Web Scraping to Extract Walmart Data

If API access is restricted, another way to obtain Walmart data is through web scraping. However, be sure to comply with Walmart's robots.txt guidelines to avoid violating their policies.

Python Example: Scraping Walmart Product Data

import requests
from bs4 import BeautifulSoup
url = "https://www.walmart.com/search?q=laptop"
headers = {"User-Agent": "Mozilla/5.0"}
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, "html.parser")
for item in soup.select(".search-result-gridview-item"):
title = item.select_one(".product-title").text.strip()
print(title)

This script extracts product names from Walmart's search results page.

4. Use Luckdata Walmart API (No Official Credentials Required)

If you don’t want to register for Walmart’s developer account, you can use Luckdata’s Walmart API, which provides easy access without official verification.

Luckdata API Overview

Luckdata's Walmart API enables developers to access Walmart’s product catalog, supporting:

• Product search

• Detailed product information

• Customer reviews retrieval

Luckdata API Free Plan

• Free Plan: 100 requests/month, 1 request/second

• Basic Plan: $87.0/month, 58,000 requests/month, 5 requests/second

• Pro Plan: $299.0/month, 230,000 requests/month, 10 requests/second

• Ultra Plan: $825.0/month, 750,000 requests/month, 15 requests/second

Luckdata API Example

Python: Calling Luckdata Walmart API

import requests
headers = {
'X-Luckdata-Api-Key': 'your luckdata key'
}
response = requests.get(
'https://luckdata.io/api/walmart-API/get_vwzq?url=https://www.walmart.com/ip/439625664',
headers=headers
)
print(response.json())

Java: Calling Luckdata Walmart API

import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://luckdata.io/api/walmart-API/get_vwzq?url=https://www.walmart.com/ip/439625664"))
.GET()
.setHeader("X-Luckdata-Api-Key", "your luckdata key")
.build();
HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());

Luckdata API eliminates the need for official Walmart authentication, making it a great alternative for developers needing quick access.

5. Choosing the Best Approach

If you are a Walmart Marketplace seller, the official API is your best option. If you only need public product data, RSS feeds or Luckdata API may be the easiest solutions. For those unable to access API data, web scraping is an alternative, but it must be used responsibly.

By selecting the right approach, you can access Walmart’s data at minimal cost while ensuring compliance with Walmart’s policies.
