Exploring Walmart API Core Endpoints: Unlocking the Secret Channel of Retail Data

2025-04-02

What is an API? What can Walmart API do?

In daily life, when we go to a restaurant to order food, the waiter communicates with the kitchen to bring us the dishes we need. An API (Application Programming Interface) is like this waiter, helping different software systems exchange information. For example, a weather app on your phone uses an API to fetch the latest weather data from a remote server.

So, what is Walmart API? It is an interface provided by Walmart that allows developers, merchants, and data analysts to access its product, inventory, order, and other data. For example, merchants can use the API to check the stock levels of a product to avoid overselling or stockouts, and data analysts can collect product prices for market trend analysis.

Additionally, third-party Walmart API services, such as Luckdata’s Walmart API, offer more flexible access and different pricing plans. It supports API calls in various programming languages like Python, CURL, Java, C#, JavaScript, PHP, Go, etc., making it easier for developers to obtain Walmart’s data.

Basics of Getting Started with Walmart API

Before using the Walmart API, you need to obtain an API key, which acts as a pass to access Walmart's data. The Walmart API key can be obtained by registering at the Walmart Developer Portal, while Luckdata API also provides different levels of access, including:

Free Version: 100 credits/month, 1 request per second
Basic Version ($87/month): 58,000 credits/month, 5 requests per second
Pro Version ($299/month): 230,000 credits/month, 10 requests per second
Ultra Version ($825/month): 750,000 credits/month, 15 requests per second

All API versions provide the same functionality, but different levels of access cater to different needs of developers.

Basic API Request Structure:

URL: The endpoint URL for API access, such as https://api.walmart.com/v3/items or Luckdata's https://luckdata.io/api/walmart-API/get_vwzq
HTTP Method: GET (retrieve data), POST (submit data), PUT (update data), DELETE (delete data)
Request Headers: Authentication (API key), data format (JSON), etc.
Request Parameters: For querying specific products, you may need parameters like productId or sku

Luckdata API Example (Product Details Query):

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

API responses are typically in JSON format, like this:

{ "productId": "123456", "name": "Wireless Headphones", "price": 29.99, "stock": 50 }

Overview of Walmart API Core Endpoints

Walmart API offers several core endpoints, each with different purposes:

1. Product API

Used to retrieve product information from Walmart's platform, such as name, price, inventory status, description, etc. It’s suitable for e-commerce sites, price comparison tools, and market analysis applications.

2. Inventory API

Used to retrieve and update inventory data, helping merchants manage stock levels and prevent overselling or stockouts. For example, merchants can use the API to query real-time stock of a popular product and restock accordingly.

3. Order API

Used for managing orders, including checking order status, creating orders, and updating order information. It’s suitable for logistics systems and e-commerce back-end management systems.

4. Search API (Provided by Luckdata)

Luckdata API offers a search feature, allowing users to search for products on Walmart by keywords and retrieve a list of matching products.

5. Review API (Provided by Luckdata)

Luckdata API supports retrieving product reviews, helping merchants analyze customer feedback and optimize product strategies.

Luckdata API Example (Search for "computer" related products):

import requests
headers = {
'X-Luckdata-Api-Key': 'your luckdata key'
}
response = requests.get(
'https://luckdata.io/api/walmart-API/get_hugc?url={url}?page=1&keyword=computer',
headers=headers,
)
print(response.json())

Detailed Explanation of Core Endpoints with Practical Examples

1. Product API: Opening the Gateway to Product Information

Function: Retrieve product details on Walmart’s platform, such as name, price, and stock status.
Target Audience: E-commerce developers, market analysts, price comparison tool developers.

Walmart API Example (Retrieve Product Info):

curl -X GET "https://api.walmart.com/v3/items/123456" \ -H "Authorization: Bearer YOUR_API_KEY"

Luckdata API Example (Retrieve Product Info):

response = requests.get(
'https://luckdata.io/api/walmart-API/get_vwzq?url={url}?classType=VARIANT',
headers=headers,
)

2. Inventory API: Keep Track of Stock in Real-Time

Function: View and update product inventory information.
Target Audience: Merchants, inventory management system developers.

Walmart API Example (Check Inventory):

curl -X GET "https://api.walmart.com/v3/inventory/123456" \ -H "Authorization: Bearer YOUR_API_KEY"

The Inventory API is critical for merchants to adjust stock levels in real-time and avoid sales disruptions or stockpiling.

3. Order API: The Powerful Assistant for Order Management

Function: Create, query, and update order statuses.
Target Audience: Merchants, logistics management system developers.

Walmart API Example (Check Order Status):

curl -X GET "https://api.walmart.com/v3/orders/789012" \ -H "Authorization: Bearer YOUR_API_KEY"

With the Order API, merchants can automate order processing, reducing manual intervention and improving efficiency.

4. Review API: Analyze Customer Feedback (Provided by Luckdata)

Function: Retrieve user reviews for products, helping merchants optimize product offerings and marketing strategies.

Luckdata API Example (Retrieve Product Reviews):

response = requests.get(
'https://luckdata.io/api/walmart-API/get_v1me?url={url}?sku={ID}&page=1',
headers=headers,
)

The Review API is essential for merchants to analyze customer satisfaction and improve sales strategies.

Error Handling and Best Practices

Status Code	Meaning	Solution
200	Request Successful	Normal data response
400	Bad Request	Check parameter format, spelling errors
401	Unauthorized	Ensure API key is correct and valid
403	Forbidden	Make sure API permissions allow access to the endpoint
404	Not Found	Ensure requested product ID, order number, etc., is correct
429	Rate Limit Exceeded	Reduce request frequency, control API calls
500	Server Error	Could be a Walmart server issue, try again later

try:
response = requests.get('https://api.walmart.com/v3/items/123456', headers=headers)
response.raise_for_status()
print(response.json())
except requests.exceptions.RequestException as err:
print("Request Exception:", err)

Why These Core Endpoints Matter?

Developers: Can use the Automation of e-commerce systems, price comparison tools, inventory management systems.
Merchants: Monitor stock levels using the Inventory API, avoid stockouts; optimize order processing with the Order API.
Market Analysts: Collect Walmart product data using the Product API and Search API for market trend analysis.
