ShoppingExploring WalmartLabs' Public API Docs
WalmartLabs provides a set of public APIs that developers can use to build applications that leverage Walmart's vast product catalog and search capabilities. The API documentation can be found at https://developer.walmartlabs.com/docs.
Getting Started
Before you can use the WalmartLabs API, you will need to sign up for a developer account and obtain an API key. Once you have your API key, you can start making API requests.
Let's start with a simple example of using the Walmart Search API to search for a product:
const API_KEY = 'your_api_key';
const searchUrl = `https://api.walmartlabs.com/v1/search?query=iphone&apiKey=${API_KEY}`;
fetch(searchUrl)
.then(response => response.json())
.then(data => console.log(data));
In this example, we're using the fetch function to send a GET request to the Walmart Search API with a search query for "iphone". We're passing our API key as a query parameter. When we receive the response, we're logging the JSON data to the console.
Product Lookup
Another useful API endpoint is the Product Lookup API, which allows you to retrieve information about a specific product by its Walmart ID:
const API_KEY = 'your_api_key';
const productId = '10753272';
const lookupUrl = `https://api.walmartlabs.com/v1/items/${productId}?apiKey=${API_KEY}`;
fetch(lookupUrl)
.then(response => response.json())
.then(data => console.log(data));
In this example, we're using the fetch function to send a GET request to the Product Lookup API with the Walmart ID of a product (in this case, an iPhone). We're passing our API key as a query parameter. When we receive the response, we're logging the JSON data to the console.
Recommendations
One of the more advanced features of the Walmart API is the ability to retrieve product recommendations based on a user's purchase history. To use this feature, you'll need to authenticate the user and retrieve their purchase history. Then, you can send a GET request to the Product Recommendations API:
const API_KEY = 'your_api_key';
const userId = '123456789';
const historyUrl = `https://api.walmartlabs.com/v1/users/${userId}/history?apiKey=${API_KEY}`;
fetch(historyUrl)
.then(response => response.json())
.then(data => {
const productIds = data.items.map(item => item.itemId).join(',');
const recommendUrl = `https://api.walmartlabs.com/v1/nbp?apiKey=${API_KEY}&itemId=${productIds}`;
fetch(recommendUrl)
.then(response => response.json())
.then(data => console.log(data));
});
In this example, we're using the fetch function to send a GET request to the User Purchase History API with a user ID. We're passing our API key as a query parameter. When we receive the response, we're extracting the product IDs from the purchase history and using them to send a GET request to the Product Recommendations API. When we receive the recommendations, we're logging the JSON data to the console.
Conclusion
The WalmartLabs Public API provides a powerful way to access Walmart's product catalog and search capabilities. By making use of the API endpoints, developers can build applications that are more intelligent and user-friendly. With the sample code provided above, you can get started with the API in no time.
