A Developer's Guide to the AliExpress API

by Adrian Machado

The AliExpress API opens up a world of opportunities for e-commerce businesses, retailers, and affiliates. This powerful tool automates various processes, from product information retrieval to order management, streamlining operations for those leveraging the AliExpress platform. This guide explores the intricacies of this API, examines its capabilities, and discovers alternatives for those seeking different solutions.

AliExpress API: Features, Limitations, and Access#

The AliExpress API boasts an array of features to improve e-commerce operations. It allows users to fetch detailed product information, including IDs, images, variants, and prices. For retailers, the API provides tools to manage product information and facilitate online retail operations. Price management is another key feature, enabling users to update product prices via the Feed API or through batch updates.

One of the API's standout features is its order management capabilities. Users can seamlessly place orders and manage other e-commerce operations directly from their websites. The API's automation prowess extends to integrating AliExpress content into various content management systems or website builders, offering high customization options for displaying reviews, ratings, and other product information.

However, the API does come with certain limitations. Access is restricted and requires approval, involving a process where businesses must submit their requirements and integration goals. Geographic restrictions also apply to seller accounts. Additionally, there's no clear method to obtain product descriptions directly through the API.

What APIs does AliExpress Offer#

AliExpress offers APIs for the following actions on their platform:

Does AliExpress offer an OpenAPI/Swagger Specification?#

Unfortunately, AliExpress does not offer an OpenAPI spec. I always find this frustrating so I snooped around their network requests and found a proprietary format they use to document their endpoints. Using some AI, Typescript, and Zuplo - I quickly created an API that will convert this format to OpenAPI for you!

How to Get an API Key#

To gain access to the AliExpress API, users must follow several steps. Here is a detailed guide:

1. Create a Seller's Account:

   • Register at the AliExpress Seller Center by selecting your country and filling out the necessary form.
   • A verification code will be sent to your email for account activation.

2. Create a Developer Account:

   • Visit the AliExpress Developers Portal and sign in with your Seller's account credentials.
   • Read and agree to the Open Platform Agreement.

3. Submit Developer Information:

   • Fill out a form with your developer's information, including contact details and company information.

4. Apply for an Application:

   • Go to the "App Management" tab on the Console.
   • Create an app, select 'Self Developer' as the app type, and provide the required company and app-specific details.

After submission, AliExpress will process the application within 1-2 business days, and decisions will be communicated via email. Once approved, developers receive an App Key and secret key necessary for further integration and development.

Understanding AliExpress: more than just an e-commerce platform#

AliExpress has established itself as a global online retail powerhouse since its launch in 2010. As a subsidiary of the Alibaba Group, it serves as a marketplace connecting buyers worldwide with Chinese sellers, focusing primarily on business-to-consumer (B2C) transactions.

Unlike traditional retailers, AliExpress doesn't sell products directly. Instead, it provides a platform for independent sellers to list and sell their goods, similar to eBay or Amazon, but with a focus on Chinese merchants. The platform offers an extensive range of products, from clothing and electronics to home décor and sporting goods.

AliExpress caters to an international audience, with a strong presence in countries like Russia, Brazil, the United States, and various European nations. It supports multiple payment methods and shipping options, though shipments from China can take several weeks and may incur import duties.

The platform has gained particular popularity in the dropshipping community. It allows sellers to list AliExpress products in their stores and have items shipped directly to customers without holding inventory. While AliExpress is considered a legitimate and safe platform offering buyer protection, users should remain cautious of potential low-quality or replica products.

Leveraging the AliExpress API: Benefits and use cases#

The AliExpress API offers many advantages that can improve various aspects of e-commerce operations. It enables efficient data extraction, providing real-time access to product information, pricing, and inventory updates. This capability streamlines market research, allowing for effective competitor analysis and price comparisons.

The API automated order management feature is particularly valuable for businesses involved in drop shipping. It simplifies order processing, syncing orders, and tracking updates, reducing manual work and potential errors.

Several use cases highlight the API versatility. Price comparison and monitoring become effortless, allowing businesses to stay competitive. Inventory management is streamlined through synchronization between systems and AliExpress. The API also facilitates in-depth competitor analysis and market research, providing insights into consumer trends and preferences.

For affiliate marketers, the API grants access to AliExpress's extensive product catalog, enabling effective product promotion. Geo-location based pricing becomes possible, allowing businesses to adjust prices based on regional factors. The API also simplifies product listing and integration, making it easier for e-commerce platforms to incorporate AliExpress's extensive product offerings.

Implementing the AliExpress API: A Practical Guide#

Implementing the AliExpress API requires careful attention to detail. Here's a step-by-step guide using JavaScript and curl examples:

const crypto = require("crypto");

const API_SECRET = "YOUR_API_SECRET";
const API_KEY = "YOUR_API_KEY";

const signRequest = (parameters) => {
  const sortedParams = Object.keys(parameters)
    .sort()
    .reduce((acc, key) => {
      acc[key] = parameters[key];
      return acc;
    }, {});

  const sortedString = Object.keys(sortedParams).reduce((acc, key) => {
    return `${acc}${key}${sortedParams[key]}`;
  }, "");

  const bookstandString = `${API_SECRET}${sortedString}${API_SECRET}`;
  const signedString = crypto
    .createHash("md5")
    .update(bookstandString, "utf8")
    .digest("hex")
    .toUpperCase();
  return signedString;
};

const timestamp = new Date()
  .toISOString()
  .replace(/T|Z/g, " ")
  .replace(/\..+/g, "");
const payload = {
  method: "aliexpress.affiliate.productdetail.get",
  app_key: API_KEY,
  sign_method: "md5",
  timestamp,
  format: "json",
  v: "2.0",
  product_ids: "4000669887458", // Example product ID
  target_currency: "USD",
  target_language: "EN",
};

const sign = signRequest(payload);
const allParams = { ...payload, sign };

fetch("http://gw.api.taobao.com/router/rest", {
  method: "POST",
  headers: {
    "Content-Type": "application/x-www-form-urlencoded;charset=utf-8",
  },
  body: new URLSearchParams(allParams),
})
  .then((response) => response.json())
  .then((data) => console.log(data))
  .catch((error) => console.error("Error:", error));

For those preferring to use curl:

curl -X POST \
  http://gw.api.taobao.com/router/rest \
  -H 'Content-Type: application/x-www-form-urlencoded;charset=utf-8' \
  -d 'app_key=YOUR_API_KEY&method=aliexpress.affiliate.productdetail.get&sign_method=md5&timestamp=2024-10-02%2014:30:00&format=json&v=2.0&product_ids=4000669887458&target_currency=USD&target_language=EN&sign=GENERATED_SIGNATURE'

Remember to generate the sign parameter using the same signing process as in the JavaScript example. If authentication is required, include the appropriate headers in your requests.

Alternatives to the AliExpress API#

While the AliExpress API is powerful, it may not suit everyone's needs. Several alternatives offer similar functionalities:
